Testing for Vitamin B12 Deficiency (Order THESE 4 Lab Tests)

How to test for Vitamin B12 deficiency. These 4 lab tests must be ordered to check if you have a B12 deficiency.
Vitamin B12 deficiency is INCREDIBLY common and most doctors are NOT testing for it correctly.
The most commonly ordered test looking for B12 deficiency is the serum B12 test but this test falls short in MANY cases. While it tells you how much B12 is in the bloodstream it does NOT tell you if your body can utilize that B12.
The good news is that there are other tests which you can order which tell you if your body can use your B12 or not. These tests are FAR more helpful than serum B12 and they must be ordered if you want to get an accurate picture of your B12 status.
If you suspect that you have a vitamin B12 deficiency, or if you just want to stay healthy, then you need to get these 4 lab tests!
Additional tests include:
Methylmalonic acid, the MCV, and homocysteine levels. The video explains what these tests mean and how to interpret your results!

Basically most doctors are ignorant on this basic stuff .

Yes, I asked my friend to check homocysteine, because we are vegan and high homocysteine means higher stroke risk for vegans. The doctor refused to test. I seriously hate how uneducated most doctors are.

I think i will hardly ever find a better explanation about B12 diagnostication methods , thank you so much Doctor Childs !

Welcome!

[@johnmoore1495]

For anyone having issues getting the lab tests run or you simply don't want to deal with your doctor, you can buy the lab tests directly from Ulta Lab Tests for really cheap in comparison to other online labs or even your normal doctor. B12 Serum is $26 Homocysteine is $34 CBC with Differential and Platelets is $20 *Total: $80* Usually they have a 20% off promo, so more like $64 There's also a lab draw fee of $7-$8 *So the true total is $72* In my opinion as long as you're getting B12 tested you might as well upgrade to the B12 and Folate test which is $38 (so $12 more.) You can also order the MMA test for $129, however I don't believe it's necessary if you're getting the other 3.

[@teeski693]

Thank you Dr .Childs! I've watched a couple videos on how homocysteine can be used to check for b-12 issues and yours has been the easiest to understand so far. Also, thanks for the tip on MCV. Mine is 96.1 & I kept feeling that was inching up a bit, but I did not want to mention it to my Dr. as it's still 'in the green' on the lab's range.

[@banzobeans]

Given low serum Folate levels and high homocysteine levels: Does a low MMA test result rule out functional B12 deficiency? Or do I need to re-assess B12 status after fixing the folate deficiency? (i.e. could the low folate be slowing down all processes involving B12? Could MMA show up as high after increasing folate availability in the body?)

You can also test Active B12 (holotranscobalamin) and do a test on your spine I think

[@user-ck9gv7kr9i]

For those who like to know I found the Difference between the two forms is that active B12 is the form used by the body, total B12 is not. It's the levels of active B12 we really need to be concerned with if we are worried about thyroid issues, fatigue or any other symptoms Issued with B12 deficiency.

hi Dr Childs i fired my GP a yr or so ago because he refuses to talk about b12 deficiency. several yrs ago i was treated with a few monthly injectections. i was taught how to do myself with another dr before he left to go work in Chili. he and i buil up a good patient /dr relatio ship over ma y yrs. he treated my daughter born with a very rare lung disease. so the fired dr only kept my meds goin for a few months, giving me time to find a new dr. as it is, there isnt any drs in canada, let alone my city ottawa. so he said he would take me back as long as i did not mention b12 deficiency. this really pisses me off because i know i have it, all the neurological symtoms. memory, tingling, fatigue, you name it. i belong to a coup,e of b12 groups on line and own 2 b12 books. Could it be b12...? by sally Palochok and her videos are online on utube. also dr Joseph Chandy has a book out on b12 deficiency. which i own. i refer to them often for others. i wish i could afford to buy lfor my dr. drs dont mmention u need folIc acid or iron, potassium, magnesium as cofactors with supplements. they are very ignorant on b12 deficiency.. kathy in canada.
