A Vitamin A Deficiency Screen measures retinol in the blood to determine whether reserves are adequate.
About Vitamin A Deficiency Test in Port Huron
This blood test is used to evaluate Vitamin A levels for deficiencies. Vitamin A (Retinol) plays an important role in the formation of rhodopsin, a pigment in the retina that is essential for vision in low light.
Retinol is the primary circulating form of vitamin A and the most reliable indicator of overall status. Because the liver holds the majority of the body's vitamin A stores, blood retinol can remain within range even when liver reserves are beginning to fall, which is why results are interpreted alongside symptoms, diet, and clinical history.
Deficiency can develop when intake is persistently low, when fat absorption is impaired by conditions affecting the pancreas, liver, or intestine, or when needs increase during periods of growth, pregnancy, or illness. Night blindness is often the earliest functional sign, followed by changes to the conjunctiva and cornea if the shortfall continues.
Testing is typically ordered when there is a clinical suspicion of deficiency, when a person has a condition that interferes with fat-soluble vitamin absorption, or when monitoring known risk factors. Results are reported as a concentration of retinol, and providers compare the value against established reference intervals to decide whether supplementation or further evaluation is appropriate.
