Criteria For Best Vitamin B12 Deficiency Blood Test
Test Directly For Vitamin B-12:
Some tests measure Vitamin B levels generally speaking, which includes Vitamins B1-B12 and others. We chose tests which only tested for Vitamin B-12. However, you should know that low levels of Vitamin B-12 often correlate with low levels of folic acid too.
We chose vendors that had been certified by the Clinical Laboratory Improvement Amendments (CLIA). We also looked at each service’s third-party evaluations and Better Business Bureau ratings.
We looked for websites that provide detailed explanations of tests, give results in an easy-to-understand format, allow you to track your health as you schedule additional tests, give you access to health professionals, provide medical education and offer rapid results.

What is Vitamin B-12?
Vitamin B-12 is essential for the proper functioning of the brain and nervous system, as well as blood formation.
It is involved in the metabolism of every cell in the body, particularly DNA synthesis and regulation, fatty acid synthesis, and energy production.
Vitamin B-12 Deficiency Anemia
Vitamin B-12 is necessary for the formation of normal red blood cells, nerve function, and tissue and cellular repair.
You need Vitamin B-12 to make healthy red blood cells, which transport oxygen throughout your body. When you lack Vitamin B-12, blood cell production is affected.
By extension, your tissues and organs don’t get enough oxygen, which means your body can’t function normally.
Vitamin B-12 deficiency is a common cause of megaloblastic anemia, in which the bone marrow produces abnormally large, unusually structured, and immature red blood cells.
Vitamin B-12 is not produced in the human body but rather ingested when consuming foods such as red meat, poultry, fish, milk, eggs, and fortified products like certain breakfast cereals and bread.
Deficiencies are mainly caused by insufficient dietary intake, although this is unusual in the United States due to the number of food items that have added B12. However you may have stomach acid production issues which could cause your body to be unable to absorb Vitamin B-12.
If you are lacking Vitamin B-12, this vitamin deficiency anemia can cause the following symptoms:
- Tingling or numbness in the hands and feet
- Changes in balance and coordination
- Loss of appetite
- Mood swings
- Memory loss
Food Sources of Vitamin B-12
Vitamin B-12 is present in a variety of animal products. Unfortunately Vitamin B-12 is not commonly found in plants, so if you’re a vegan or vegetarian please consider supplementation if necessary.
You may also want to consider a folate test too, because folate and Vitamin B levels are correlated.
You may acquire Vitamin B-12 by eating items including:
- Dairy products
- Leafy green vegetables
- Some fortified breakfast cereals and nutritional yeast products
Dietary supplements or other oral supplements are ways you can overcome any type of pernicious anemia, whether due to Vitamin B12 or otherwise.
People at Risk for Vitamin Deficiency Anemia
Vitamin B-12 insufficiency disproportionately affects:
- People with a family history of anemia caused by vitamin B-12 deficiency
- Older individuals who do not have enough hydrochloric acid in their stomach
- People who have had gastric surgery, such as weight loss surgery (gastric bypass)
- People with HIV/AIDS
- Individuals with Crohn’s disease or celiac disease
- People with liver disease
- Vegetarians and vegans
What happens during a vitamin B test?
Vitamin B is tested in blood or urine. During the tests at the local health office or blood lab, syringe blood is taken from your arm using syringe needles.
This sounds scary but upon injection, a small amount of blood is collected into tubes or vials. You can feel a slight bite as the needle is inserted.
It normally takes fewer than one minute.
