Biotin (Vitamin B7) Test

This biotin blood test can help determine the amount of biotin (vitamin B7) you have in your blood. Biotin is a water-soluble vitamin that helps your body break down proteins, carbohydrates, and fats into energy. Biotin also allows cells to communicate with one another and tell genes what to do.

Identifying and addressing nutrient deficiencies are important steps toward better health. Your body does not produce most vitamins and minerals, so you must get them from food or supplements. How nutrients work in your body is influenced by more than just what you eat. These factors include genetics, age, health conditions, medications, metabolism, and how well your body absorbs nutrients.

No doctor’s visit needed. Buy this biotin deficiency test and visit a nearby Quest location.
