What it measures
- Retinol — The main form of vitamin A circulating in the blood; this is the most common marker measured.
- Retinyl esters — A storage form of vitamin A; high levels may suggest too much vitamin A.
- Beta-carotene — A plant-based precursor that the body converts into vitamin A; sometimes measured to assess intake.
- Retinol-binding protein — A protein that carries vitamin A in the blood; low levels can occur with poor nutrition or liver problems.
