About Vitamin A Deficiency Test in Pacifica
The Vitamin A Deficiency Test provides a direct measurement of retinol, the primary circulating form of vitamin A.
Vitamin A encompasses a group of related compounds, including retinol, retinal, and retinoic acid. Retinol is the form most commonly measured in blood because it reflects bodily stores and recent intake. This test quantifies retinol concentration to assess whether levels fall below the reference range.
Deficiency can arise from inadequate dietary intake of preformed vitamin A or provitamin A carotenoids, or from conditions that hinder fat absorption, such as certain gastrointestinal disorders. Symptoms may include night blindness, dry eyes, and increased susceptibility to infections. The test is typically ordered when these signs are present or when a clinician suspects malabsorption.
Results are interpreted alongside clinical findings and other laboratory data. A low retinol level suggests deficiency, but it does not identify the underlying cause. Repeat testing or additional evaluations may be recommended to confirm and monitor the condition. The test itself involves a standard blood draw and requires no special preparation beyond any instructions provided by the laboratory.
