Vitamin B7 Blood Test

This test measures the level of Vitamin B7 in a person's blood.  B7, also known as Biotin, is one of the family of B vitamins.  Vitamin B7 is necessary for metabolism and hormone production.  The body gets B vitamins from the food a person eats.  Good sources of B7 include soy, egg yolks, legumes, peanuts, bananas and grapefruit.  Deficiency in Vitamin B7 is rare but may occur in people who are malnourished or are receiving intravenous (parenteral) nutrition. 

This test is typically ordered when someone has symptoms of B7 deficiency such as hair loss, muscle pain, fatigue or the development of a red rash around the eyes, nose, mouth and genital area.  Vitamin B7 testing may also be ordered to monitor pregnant women or people with malabsorption disorders.
