Vitamin B1, B2, B6

One or more B vitamin tests may be used to screen for and detect deficiencies in people with characteristic symptoms.

Testing may also be used for those who have a condition that puts them at risk of B vitamin deficiencies. This may include individuals with a limited or inadequate diet, those with signs of malnutrition, those being given their nutrition intravenously (parenteral nutrition), and those who have had gastric bypass surgery. Testing may also be performed for those with alcoholism or with chronic diseases associated with malabsorption, such as Celiac disease.

Testing is primarily ordered when a person has symptoms that may be due to a B vitamin deficiency.

Test results that are low may indicate a B vitamin deficiency but will not reveal whether it is due to an inadequate supply or an inability to absorb or use available B vitamins. When someone is deficient, the person often has multiple vitamin deficiencies.

If test results are normal, then it is more likely that a person’s symptoms are due to another cause.

A high B vitamin level may be associated with vitamin toxicity. This rarely occurs and when it does, it is usually due to exposure to high doses of the vitamin.
