About Vitamin A Deficiency Test in Port Huron
The Vitamin A Deficiency Screen is a blood test that quantifies retinol, the primary circulating form of vitamin A.
Retinol travels in the bloodstream bound to a carrier protein, so its concentration reflects the amount of vitamin A available to tissues. Clinicians order this test when a patient has symptoms or risk factors that suggest insufficient vitamin A, such as night blindness, dry eyes, or a history of malabsorption.
Because vitamin A is stored in the liver, blood levels may remain normal until reserves are depleted. For this reason, results are interpreted alongside a patient's diet, medical history, and other laboratory findings rather than in isolation.
The test requires a standard blood draw, and the sample is analyzed in a laboratory. Results are typically reported within a few business days, though the exact timeframe depends on the facility performing the analysis.
