FatigueWeaknessDepressionBrain fogMental Changes from B12 Deficiency
Yet clinicians
ALMOST NEVER suspect these common symptoms as being from
B12 Malapsorption, instead often calling them
Early Symptoms of Fibromyalgia or chronic fatigue syndrome. But if you are lucky enough to have your doctor suspect vitamin B12 deficiency and actually
TEST your Vitamin B 12 Levels, it’s likely that he will often do the
Wrong Test to find it! And unfortunately, when this test comes back normal, it will give you and your doctor a
FALSEbelief that you do
NOT have Vitamin B12 deficiency when you actually still might!
Macrocytic Anemia Vitamin B12 Blood Test
The first and most common Vitamin B12 blood test that is done is actually not for Vitamin B12 at all. When laboratories do a regular Complete Blood Count or ‘CBC’, they further categorize this test by measuring the SIZE of the red blood cell and the NUMBER of them on the portion of the test called an MCV Blood Test. If the cells come back larger than normal with fewer of them, you will be said to have Macrocytic Anemia- which is often CAUSED BY vitamin B12 deficiency. But macrocytic anemia often won’t occur for up to 2 years after the onset of Vitamin B12 deficiency. Doctors will often ONLY do more testing for vitamin B12 deficiency ONLY if Macrocytic Anemia is present.
So, even if you are SEVERELY deficient, if you haven’t been that way for up to 2 years, then your doctor will NOT do any further vitamin B12 testing and YOU are left to suffer!
Vitamin B 12 Levels
If you have severe symptoms and your doctor is more proactive, he MAY test your Vitamin B 12 Levels. While it seems logical that a Vitamin B12 blood test, also called a Cobalamin Level, would accurately test Vitamin B 12 levels, that assumption is VERY wrong. In fact, this simple blood test, much like the test for your Magnesium Level, is inaccurate much of the time. Especially when your Vitamin B 12 levels are towards the LOW END of normal, a Vitamin B 12 level is completely unreliable.
"Metabolic tests, such as serum methylmalonic acid (MMA)
or plasma homocysteine, can be useful when the clinical
picture is equivocal but are sometimes unreliable themselves."
How I treat cobalamin (vitamin B12) deficiency
But most doctors, who are obviously not Understanding Blood Test Results, simply look at the NORMAL range of vitamin b12 levels on the lab sheet and determine that you are NORMAL when you are actually very deficient- but a ‘low normal’ on a vitamin B12 blood test is NOT normal and SHOULD make your doctor do further testing. Unfortunately, however, in real life that does not happen and in reality, VITAMIN B12 LEVELS SHOULD SIMPLY NOT BE DONE- EVER!
So What Vitamin B12 Levels SHOULD Be Done?
If you are VERY persuasive OR you happen to have an excellent clinician, they SHOULD have skipped the inaccurate vitamin B12 blood test in the first place and instead asked for a Methylmalonic Acid Test. This test is what Vitamin B12 Levels SHOULD be! The MMA, as this test is often called, is a MUCH more accurate test for vitamin B12 deficiency than the Vitamin B12 blood test is, and it can detect low vitamin B12 levels as soon as 10 DAYS after the deficiency actually starts! Macrocytic Anemia, by contrast takes up to 2 YEARS to show up.
So, in what time frame would YOU rather be diagnosed- 10 DAYS or 2 YEARS after you have Vitamin B12 Deficiency Symptoms!

the advantages of including methylmalonic acid...
in the early evaluation of patients
with suspected deficiencies of vitamin B12..."

vs Vitamin B12 and Folate
And even better, a Methylmalonic Acid Test is inexpensive and can be done not only using blood tests, but can ALSO be done on urine- making it easy to test infants, children and elderly homebound or nursing home residents.
Yet the Methylmalonic Acid Test is hardly ever used despite its availability and despite the fact that doctors who are not Understanding Blood Test Results could be catching far more people with this devastating deficiency far earlier than using Vitamin b 12 levels or checking for macrocytic anemia.
