About Vitamin A Deficiency Test in San Ramon
The Vitamin A Deficiency Test evaluates retinol levels in the bloodstream to identify insufficient vitamin A status.
Vitamin A, also known as retinol, is necessary for the formation of rhodopsin, a pigment in the retina that enables vision in low light. It also supports immune defense, skin health, and normal growth and development.
Because vitamin A is stored in the liver, blood retinol levels reflect the balance between dietary intake, absorption, and utilization. Low concentrations may indicate inadequate intake, malabsorption, or increased demand due to illness.
This test is typically ordered when a person shows signs of deficiency, such as night blindness or dry eyes, or when a clinician suspects poor absorption related to gastrointestinal conditions. Results are interpreted alongside clinical findings and other laboratory tests.
