Zinc Blood Test

Mar 7, 2026

Zinc Blood Test

A zinc blood test measures serum zinc levels—this essential mineral is involved in over 300 enzyme reactions and affects immune function, skin health, wound healing, taste and smell, hormone production, and DNA synthesis, with deficiency causing impaired immunity, hair loss, slow wound healing, skin problems, and hormonal issues. About 15% of the global population is zinc deficient, with vegetarians, elderly, and those with digestive conditions at higher risk.

At Blood Test London, zinc testing costs from £245 with results in 2-3 days. A doctor always reviews every result.
