Vitamin B7 (Biotin)

Product detailed description

Vitamin B7 (Biotin) Blood Test

A blood test measures the level of biotin, also known as vitamin B7 or vitamin H. It can support a targeted nutritional assessment when biotin deficiency is suspected. Isolated biotin deficiency is rare, and the results should be interpreted in a broader clinical context.

Biotin and Its Role in the Body

Biotin is a water-soluble vitamin involved in the metabolism of carbohydrates, fats, and proteins. It is naturally found in foods such as eggs, meat, nuts, and other dietary sources. Biotin is also a common ingredient in B-complex supplements and products marketed for hair, skin, and nail health.

When Can Biotin Testing Be Useful?

The test may be part of a medical assessment of malnutrition or unexplained symptoms when biotin deficiency is suspected. However, hair thinning, skin changes, and brittle nails can have many other causes. A biotin blood test alone does not provide a comprehensive evaluation of hair loss, and the results do not automatically indicate a need for high-dose biotin supplementation.

Important Information Before Blood Collection

Always inform healthcare staff if you are taking biotin supplements, including the dosage and when you last took them. High doses of biotin may interfere with certain other laboratory tests, including some hormone tests. Any temporary discontinuation of biotin supplements should be determined by your doctor or the laboratory, as there is no universal approach suitable for every situation.

What Will Your Results Show?

The test provides a measured biotin level, which should be interpreted according to the laboratory's reference range, dietary habits, and supplement use. The test requires a venous blood sample, collected according to the instructions provided by the collection center.
