Biotin (Vitamin B7) details
What Biotin (Vitamin B7) shows
Biotin, or vitamin B7, is a B vitamin your body needs to help turn food into energy and to process fats and proteins. It comes from foods such as eggs, nuts, seeds and liver, and gut bacteria make some too. This test measures biotin in your blood. It can be used to look for deficiency, which is uncommon and can cause thinning hair, rashes and brittle nails, and to check high levels from supplements. A low result can point to poor intake, long-term use of certain medicines or regular eating of raw egg whites. A high level usually reflects supplement use, which matters because high biotin can interfere with many other blood tests, including some thyroid and heart tests.
Tests that include Biotin (Vitamin B7)
Biotin, vitamin B7, or vitamin H, is a water-soluble vitamin. The vitamin plays a role in transferring carbon dioxide in the metabolism of fat, carbohydrate, and protein by functioning as an enzyme cofactor. It is involved in multiple biochemical reactions, including niacin metabolism, amino acid degradation, and the formation of purine, which is an integral part of nucleic acids. It interacts with histone through the action of biotinyl-transferase.
