What this test is

The vitamin A deficiency test is a blood test that measures the amount of retinol, the primary form of vitamin A, in the blood. It helps assess whether vitamin A stores are adequate for normal vision, immune function, and skin health.

What it measures

  • Retinol — reflects circulating vitamin A levels
  • Retinol-binding protein — indicates vitamin A transport capacity
  • Total vitamin A — may include other retinoid forms

What the test involves

A healthcare professional collects a blood sample, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test if you have symptoms such as night blindness, dry eyes, or frequent infections that could indicate low vitamin A. It may also be ordered for individuals with conditions that affect nutrient absorption or those with limited dietary intake.

Preparation

Preparation instructions can vary, so follow the specific directions provided by the collection lab. Typically, no special preparation is needed, but the lab will confirm any requirements.

How results are reported

Results are reported as a numerical value that your clinician interprets. Reference ranges can differ between laboratories, so the lab's own range should be used for context.

Before you go

  • Whether fasting is required before the blood draw
  • Any medications or supplements that might affect results
  • The expected turnaround time for results
