About Vitamin A Deficiency Test in Pacifica
The Vitamin A Deficiency Test measures retinol, the primary circulating form of vitamin A, to assess whether the body has adequate stores of this essential nutrient.
Vitamin A supports the formation of rhodopsin, a pigment in the retina that enables vision in low light. It also contributes to immune defense, skin health, and the normal growth and development of cells throughout the body.
Because vitamin A is stored in the liver, blood retinol levels reflect overall nutritional status but may remain normal until liver reserves become substantially depleted. Results are therefore interpreted alongside dietary history, symptoms, and other clinical findings.
Deficiency may occur with inadequate dietary intake, fat malabsorption conditions, liver disease, or certain gastrointestinal disorders. Testing can help clarify whether low vitamin A is contributing to symptoms such as night blindness or other concerns.
