The doctor may ask you to perform this test to screen or detect moderate to severe B Vitamins deficiencies. You may also be advised to perform this test if you have a family history of B Vitamins deficiency conditions or if you experience any signs and symptoms of B Vitamins deficiency conditions.
If you have a family history of B Vitamins deficiency conditions, your doctor may ask you to perform this test on a 6-monthly basis or a yearly basis. Individuals who are diagnosed with B Vitamins deficiency should perform this test on a regular basis as instructed by the doctor.
The Vitamin B Profile has the following components i.e:- B1 (Thiamine), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine), B7 (Biotin), B9 (Folic Acid) and B12 (Cobalamin).
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your Vitamin B Profile. Your doctor will give specific instructions depending on your condition on how to prepare for Vitamin B Profile.
You may need to fast (without eating anything) for a whole night or for 6 to 8 hours before this test. However, follow all the instructions given by your healthcare provider.
If the test result falls in the normal reference range, then you have adequate levels of B Vitamins and hence, no medical intervention is necessary. If the test result falls below the normal reference range, it may indicate moderate to severe B Vitamins deficiencies. Poor nutrition intake or lack of nutrients (malnutrition), or lack of proper absorption of B Vitamins through small intestine due to Chrons disease (a disease condition of intestine) may also cause low B Vitamins blood levels.
Individuals with poor appetite and who consume alcohol also may show decreased B Vitamins blood levels. Low B Vitamins blood levels may also be seen in individuals who receive dialysis and take water pills. Women who are pregnant or breastfeeding may have decreased B Vitamins blood levels.
If the test result falls above the normal reference range, it may indicate B Vitamins toxicity. This is not very common and may occur due to the intake of high doses of B Vitamins supplements.
If you have higher or lower than normal levels of B Vitamins in the blood, consult your doctor for further instructions. Based on the test results, your doctor may advise appropriate medical treatments, lifestyle modifications, or further diagnostic tests.
