Checks for level of Vitamin B7, classified as a B-complex vitamin and also known as biotin, required by the body.

The B Vitamins are a group of water-soluble vitamins which all have an important and unique function in the functioning of the human body. Vitamin B7, also known as biotin, like most of the other B vitamins, is a coenzyme that play a pivotal role in the production of most hormones in the body, but is also needed for the metabolism of fat, protein and carbohydrates. Unlike most of the other B vitamins, B7 can in fact be made by intestinal bacteria. Therefore, B7 deficiency is very rare. If one does have a vitamin B7 deficiency it usually manifests as dry skin, brittle hair and fatigue.

This test is performed in following conditions such as:

• Seborrheic dermatitis
• Dry skin
• Brittle hair or hair loss
• Fatigue
• Intestinal tract issues like malabsorptive disorders
• Muscle pain
• Nervous system issues

Also Known As: Biotin
