TESTING YOUR BLOOD TYPE AT HOME TO PROVE YOU’RE NOT JUST LAZY, YOU’RE *SCIENTIFICALLY* LAZY.

My whole life I haven’t known my blood type and I’ve always kind of wondered about it.  Was I a glamorous and rare AB-?  A diverse and valuable O- ?  Or just some common type that probably ate plain toast for breakfast every day and had a favourite “I ❤️ cats tee shirt?”

The reason I don’t know my blood type is because in high school when we were all testing our blood in Science class, my friend fainted, and I took her to the bathroom to recuperate.  By the time we got back to class, the testing was done and I never learned if I was A, B, AB or O.  I did however learn that when you faint it’s possible you’ll pee a little in your pants and your contact lenses might pop right out of your head and land in a puddle of fainting urine on the floor.

When this spring a friend suggested he thought I was an O blood type based on my love of back breaking manual labour I started to become curious about both my blood type and his willingness to label me a type O based on how much I like to dig dirt.

It turns out there may (or may not of course) be a correlation between your general health, the foods you eat and your blood type.

Eat Right For Your Type is a diet book that was published 21 years ago.  When I say diet, I mean making the proper food choices to be the healthiest you can be, not necessarily to lose weight, although that is a possibility.  And the food choices you make should be based on your blood type.  The book goes into great detail and examples about how your blood type dictates what foods you should eat and how often to keep you at your healthiest.  It claims that your blood “reflects your internal chemistry … and actually determines the way you absorb nutrients”.*

Apparently, according the book, people who have type O blood are workhorses.  They love manual labour and their bodies thrive on it.  Blood type A on the other hand are a bit more delicate.  They’re the loungers and relaxers of the world because they’re easily agitated by stress.  And that’s how their body performs the best.  Their body actually thrives on their laziness, anything too physical or stressful is too much for their delicate little constitutions. So you blood Type As aren’t just lazy, you’re scientifically lazy, which lends a certain authority to your binge watching of Netflix shows.

Was my insatiable desire to constantly be doing stuff bred into me by my blood?? I needed to read this book.

But before I could get the book and determine whether I thought it was right or wrong I needed to find out my blood type.

My first plan was to give blood because they must have to determine your blood type if you do that.  I mean that’d be the professional thing to do, right?  Well they do, but it turned out there wasn’t a blood clinic happening near my house for another couple of months.

Plan 2.  Go to the doctor and have her schedule an appointment to have my blood tested at a clinic.  This seemed like a pain.  It involved making an actual phone call like some sort of person from the 1980’s and taking up her time on something that probably wasn’t life threatening.  At least at this point I didn’t think continuing to eat wrong for my blood type was life threatening.

I ended up going with Plan 3.

It turns out there are kits you can buy online for testing your blood type at home.  The kit includes everything you need like teeny tiny little sticks, an eyedropper, a finger poker,  and the most important thing, the Eldoncard.

An Eldoncard is a piece of paper that has been manufactured to react in certain ways to your blood.  You just drip your blood on it, swirl it around and voila.  You know your blood type. Kind of.

 

The kit costs a Canadian, $25 on Amazon, but if you’re in America, you of course, get it for about 1/3 the price.  $6.  

However, I actually found a package where you got the book Eat Right For Your Type and an Eldoncard on Amazon.ca which was just $20 for both the card and the book.  It makes no sense, but the Internet rarely does.

So you want to test your blood type at home because you’re curious and a DIYer and you love poking yourself with a sharp things.  Perfect.  You’ve come to the right post.

HOW TO TEST YOUR BLOOD TYPE AT HOME

  1.  Lay out all the components of the kit in front of you.
  2. Add a drop of water to each circle on the Eldoncard.
  3. Sterilize your finger with the alcohol wipe and then prick your finger with the lancet.
  4. Squeeze the tip of your finger to get a big drop of blood.  Using one of the plastic tools included in the kit, transfer a drop of blood to one of the card circles.
  5. Do this for each circle.
  6. Swirl the blood and water droplet together in each circle using the same plastic stick you used for gathering the blood.
  7. Tilt the card in each direction for 10 seconds.
  8. Now compare your circles of blood to determine which blood type you have.

A note about the lancet.  It doesn’t hurt at all so don’t sit there for 10 minutes putting it to your finger then taking it away, then putting it to your finger then taking it away. Then getting a drink of water.  Then coming back and putting it to your finger then taking it away.

Don’t worry.  It hurts so little you might not even be sure if it worked.

 

Keep your hand down if you can. This helps the blood rush to your fingertip if you have trouble massaging enough blood out.

Anyone pass out yet?  Are your contact lenses still in?

Remember to lay your plastic sticks with the same circle you used so you don’t cross contaminate once you have to swirl the blood and water together.

If I’m being perfectly honest with you, which I try to at least appear to be at most times, I screwed up my first kit.  I didn’t swirl the mixture around enough and I didn’t use enough blood.  Not to be beaten by a stupid paper card with circles on it, I ordered another kit and did it again with much better results.

Here’s a handy video of me making myself bleed so you can get a better idea of how to do this.

The only trouble is, after doing this test … twice … I still wasn’t really sure about what my blood type was.  I thought it looked like a B-.  Or it could be O.  But probably a B-.  Certain people have weak antigens or pathogens or anglicans or something, which would make my “Anti-B” circle hard to read.  Actually I think the word is Agglutinate.

This is the card they give you for reading your results.

 

It kind of helped, and I was pretty sure I was a B- but I wasn’t positive.  So I ended up booking an appointment at the next blood donor clinic to confirm that I was a B-.  More on that shitshow experience in a week.

And in Friday’s post you’ll learn why it is I can’t eat a good turtle burger this weekend.  So there’s that.

    I AM TOTALY SCIENTIFICALLY LAZY and to celebrate, I am gonna go eat my (ordered in) pizza in front of the tv instead of getting stuff done like I’d (not really) hoped to do. Thanks Karen for justifying this choice from now until forever.

  2. Robert says:

    Oh! Karen!

  3. Fonda says:

    I never considered myself lazy, but my mom, and subsequently my sister, called me that. It didn’t feel very good. Instead, I think I’m a contemplater — one who is a thinker. I may not be especially active, but there is much activity going on that one doesn’t see. I also proved my blood type A wrong. I was a manager in a retail store, and this required plenty of lifting, moving and thinking. I unloaded plenty of stuff from a semi truck in below-freezing temperatures. I was more physical then, but I’ve always been a thinker and had things on my mind. So, I’d rather not be called lazy, because that is only an outward appearance and has nothing to do with what is going on in the mind.

  4. Tina says:

    Are you aware that there’s a THREE MINUTE LONG ad before your video? I didn’t watch it. I hope you get paid for it anyway. I might watch a 15 second ad or even a 30 second ad. But THREE MINUTES? Wow.

    Anyway, I don’t know my blood type. I guess I could look at my last blood work but I decided I really don’t care that much. And actually I could do that in less than the 3 minute ad!

    But love you anyway!

  5. Alberta Karen says:

    Just go give blood. Helps lots’ of people. Finding out your own blood type is just an extra reward. (Besides the juice!)

  6. Elaine says:

    I just clicked on the video – haven’t watched you yet, Karen – but thought I’d let you know the ad (Airwick) that I saw was about 29 seconds.

    • Karen says:

      Thanks for letting me know Elaine. I actually have no control over those ads, they’re supplied by a company. Just like with Youtube. Sometimes they’re short, sometimes they’re long. ~ karen!

      • TucsonPatty says:

        And…I had to go back and watch the video, and I had no ad. on my iPad. Wonder if that is why? Different devices? I also am a “lazy A”, but to make up for it, I donate platelets every two weeks. When my daughter was born, I was so proud of her being an “A+” baby! It took me a minute to realize she had the same blood type as I! I still laugh when I think of it.

        • Karen says:

          No, it just depends. 🙂 Sometimes the ad space is filled and sometimes it isn’t, that’s all. Sometimes a long ad, sometimes a short one. 🙂 ~ k!

  7. MrsChrisSA says:

    Mmmmmmm – I am A+ so that makes me lazy…………………………….
    think my body is confused and not working in line with my blood!!

  8. Brenda says:

    But A+ that’s excellent if you’re going to school hi5

  9. Sherri says:

    Scientifically Lazy. Yeah, that’s about right. A-

  10. Leticia says:

    People still do blood tests in school in Canada and the US?

    Here in Brazil when it was time for me to take the test, around mid 80’s, HIV was already a thing and the schools stopped doing it. I was told it was too risky having kids messing around with blood, fear of contamination and such.

    I recently had a test done, I asked my doctor to include it in a batch of blood tests. I am A- and I am certainly lazy. Binge watching netflix is totally me.

  11. Sharon Dore says:

    Ask family members if they know their blood type – some are genetically dominant so if you know your parents or siblings, it will give you a clue

  12. Lynn says:

    My husband & I followed the suggestions in the Eat Right For Your Type book for quite awhile–a few years ago. He is A–I am O–a mixed marriage. Turns out, it isn’t that difficult to put together meals that worked for both of us. And we both felt better when we followed the eating plan–even lost a bit of weight. I am not sure why we stopped–probably some Christmas related chocolate binge that threw us off course. We are so easily tempted by the wrong things!! And I love to grub in the dirt and create things–so maybe the blood type thing really is a thing!

  13. dana says:

    Thats a cool at home kit. I have dealt w Crohns for 37 years since age 9. Theres been surgeries, many blood draws, and blood transfusions. Last October during a transfusion I finally found out Im A+. Thats probably tge only A+ I have ever received. ☺

  14. Barb says:

    I would not rely on this to determine how to best live. I am an A+ and I work my butt off at work, in the gym, and gardening. My ex-bestie is an O. And she is absolutely the most lazy self-centered person I have ever met. For that matter, the other ‘O’ I know is too. It’s all exercise and diet to be healthy, the magic formula is eat more vegies less junk, and we know it.

    • Karen says:

      You’d have to take a look at the book and read the examples. It isn’t a “diet” its about how people with different blood types are more prone to various diseases/conditions etc. I’m not fully endorsing it as a miracle plan but scientifically it made sense. ~ k!

  15. Debbie D says:

    Knew you had to be a B (my blood type although I am B*). I too am a workhorse in the garden, creative, love to plan things for my home, a doer. Yup. You are definately a B! Oh, and modest too!

    BTW, the medical industry will never take your word that you are a certain blood type. Each time you are hospitalized, give blood, etc., you will be typed again, just to make sure.

  16. Kelly says:

    Oh, that’s funny! My mother-in-law is definitely an A-something and I know I’m a common O+. I’d rather lift rocks than sit around and drink beer. It-all-makes-sense-now. 😉

  17. Paula Clark says:

    I am A- and was the work horse type person until I worked my entire back into a frenzy and have had to cut back on most work horse activities. I had 65 good working years so cutting back wasn’t as hard as I thought it would be. So no, the book is not accurate for me. My husband is an O person and truth be told, he can be lazy. Very lazy.

  18. marilyn meagher says:

    You can skip the ad 5 seconds into it …I’m b+ which matches my approach to life in general and I have 54 blood donations under my belt . Our family all donated regularly and some still do, inspired by our parents who donated all their lives ..it’s such a simple thing to do but saves so many lives. There is a chronic shortage so if you can donate please do!!

  19. Katie C. says:

    So I’m B+. What does being a B mean for our personalities?

  20. Darlene Meyers says:

    I am so surprised that so many do not know their blood type…

  21. Ha, I’m diverse and valuable. 😉
    How interesting that your blood type would be able to tell you things about yourself. I mean, it makes total sense,the thought had just never crossed my mind. Now, instead of, “What’s your sign?”, we can all start carrying lancets around in our purses.

  22. Joy says:

    No, please, don’t fall down the “blood type diet” rabbit hole. Blood type is based on a few (of many) types of proteins on the surfaces of red blood cells. Put the wrong type blood into a transfusion and it’s Clot City throughout your circulatory system. Trouble. That’s why we want to know blood type. There’s no evidence that your blood type determines the best kind of diet for you, or says anything at all about your personality. Here’s one analysis of 16 research studies, from the American Journal of Clinical Nutrition: http://ajcn.nutrition.org/content/98/1/99.full But, looking at your results, you are definitely a B negative and by definition, uncommon and valuable.

  23. Andrea Lanyi says:

    I read the book 20 yrs ago; if you read the entire thing, its full of discrepancies from blood type to blood type. My Japanese friends really liked the part where type B, (Which most of them are) should not eat soy products. Actually, the ‘latest’ info is that almost all lectins are bad for humans , so I’ve decided that it’s safer and healthier to not eat.

  24. Sabina says:

    I call BUNK! I’m an A+ and have always loved doing physical labor. My gardens are all planned, dug, installed and maintained by me and that’s just a small part of the “physical” stuff I do. I’ve been a single-mom-homeowner for 23 years now without unlimited funds so you can imagine my days are not unlike yours (which is why I took to your blog immediately and follow religiously)…(the only blog I follow by the way). To pay the bills (and to have money to buy more plants and dig more beds) I have a boring desk job which finds me gazing out the window daydreaming about all the more productive (aka fun) things to do outside of here. Like today… today I opened the email I’ve been waiting for telling me that peaches are ready to pick! I’ve got bourbon peach jam to make, I’ve got peach salsa to make and I’ve got peaches to can for that longed-for-taste-of-summer in January to savor! Damn desk job…I think I’ll leave early…

  25. Kelly H says:

    Congrats on being B-. You are one of the rare few. You should really seriously consider donating your blood. Your blood would be something special, and may actually be very needed.
    Most blood banks have mobile units that set up in out of way places, if you live in the boonies. Since you can only donate once every 2 months, it may be worth the drive knowing you are totally going to save a life. If you live closer to town, just make an appointment with your local blood bank.

  26. Linda in Illinois says:

    I have placed an order for the card and the book, I assume you will get credit for it. Thank you Karen, I always wanted to know what my blood type is. The only thing I know about my blood is that I carry the Spinabifida genes and my 41 year old daughter suffers for my bad blood. I have had many tests but no one ever told me type and I always forgot to ask. This will be a good chance to do it in the privacy of my own home.

  27. Jody says:

    I knew you were special. Only 2% of the population have B- blood type. Canadian Blood Services and people need your blood! It’s in you to give.

  28. Alena says:

    Thank you, Karen, for the scientific justification that I am not meant for manual labour. I am the delicate A-type, prone to stress, and there best to recline on a chaise lounge for the major part of the day. Something went wrong though and I ended up in a very stressful job where I feel like the donkey waiting for the last straw to break its (mine) back.
    I am not paying $25 to order a kit – I am pretty sure I am type A. I am interested to know, though, what I am supposed to eat to be healthy (I had a huge smoothie (750 ml) for lunch consisting of kale, dandelion, spinach, red beet, strawberries, red and black currant, and a piece of turmeric root (not in love with the last ingredient – that was the first time I tried it). That smoothie must be good for ANY blood type!

  29. Jennie Lee says:

    I’m O-. It’s frustrating, now that I’m 64, and have arthritis. I’ve always wanted to be doing and fixing and creating things, and now there are a lot of things I can’t do. All my walls and ceilings need to be painted, and it bugs me! By the way, it’s important for girls to know if they’re RH negative. If I’d known, MAYBE I could have avoided a miscarriage, long ago.

  30. Kelly says:

    I’m an A+ and in school that’s as good as it gets, so I guess I’m awesome. The Eat Right for Your Blood Type book I did not find to be awesome. Actually, I dropped it off in the church donation area last week. I have quite a few food intolerances and it recommended that I eat those, which isn’t going to happen. I didn’t find any of the information to be helpful at all.

  31. Peg says:

    You could have donated a pint to the red cross. Win/win. You’ve helped out someone and they will send or tell you your blood. O – here so I do a double red donation 2 pints at once a few times a year. I’ll have to check out book, I’m a workhorse I think.

    • Karen says:

      I am going to take a leap of judgement here and guess that you skimmed the post, lol. Near the beginning I said it was 2 months before there was a blood clinic in my neighbourhood, then in the later part of the post I talk about how I did indeed end up going to a blood donor clinic (with a post on that to follow in the next week or so) ~ karen!

  32. MindyK says:

    Thank heaven I already know my type, because just looking at the photos made me woozy. I’ll skip the video, thanks. 😉

  33. Miss willow glen says:

    So if I am rare B- than what is my son super rare AB-.what is it that we should do to help.

  34. Nancy Blue Moon says:

    That was a hell of a lot of money to spend to find out something you are not really sure of girl…don’t you ever get bloodwork done?…Shouldn’t it be in your medical records?

    • Nancy Blue Moon says:

      Oh yeah…I don’t need a blood test to tell me I’m lazy! 😸

    • Karen says:

      🙂 For most people it would be much more obvious. Even if they do blood work, if the dr. doesn’t specifically ask for your blood type to be tested they don’t do it. I’ve never had mine tested and I’ve never needed blood so nope … not in my records. ~ karen!

  35. Josephine says:

    I am a super-savor O-, however I don’t particularly like manual labor. Is there s subset to blood types? Perhaps I’m A in someway.

    I have read that blood type diet book. It’s actually very interesting. Even if you just read through your blood type, it’s very interesting. Totally explained why DH won’t eat veggies and why I happen to love them.

  36. I have no idea what type I am. I have anemia issues so I can’t donate blood, and I asked my mom a while ago and she said she had no idea. Thanks, mom. I suppose that’s the type of medical info a 33-year-old is supposed to know herself.

    I’m interested to know, not so much about foods, but about the work ‘ethic’.

  37. Carlene says:

    I did one of these years ago. It was 1/2 accurate — after lab bloodwork a couple years ago, it turns out I’m AB+, and the at-home kit pegged me as AB-. It was a surprising letdown to go from super duper rare to just very rare 🙂

  38. Brigette says:

    I’ve been wondering this for so long, but also wasn’t willing to make a separate appointment about it. For the price I think it’ll be a really fun home experiment even if it is a little tough to read.
    PS I’ve read so many of your book recommendations from previous blog posts lately and really enjoyed each book. I never would have picked up Jurassic Park if it weren’t for you!

  39. Kayla Dean says:

    I’m sorry, but you’re not B-. Even the smallest aggulinate still counts. You wonder why the Eldoncard gets its accuracy downrated because you misread your results. By your results you are either AB+ or B+.

    • Karen says:

      I’m not sure why or how you’re qualified to make that definitive call. I actually got my blood officially tested a few weeks later when I gave blood and yes, I am indeed B-. ~ karen!

  40. Kayla Dean says:

    Well, to confirm I’d actually need proof or update on accuracy of the Eldoncard. Most doctors don’t approve of it.
