Vitamin A Blood Test

Measures retinol in serum.

Measures

Retinol in serum.

Why it matters

Vitamin A is used in vision, immune function and cell growth. It's fat-soluble, which means the body stores it — and unlike water-soluble vitamins, excess isn't simply excreted.

That storage capacity is exactly why measuring rather than assuming makes sense if you're supplementing.

Before you collect

Note vitamin A or multivitamin supplementation and dose. Fasting is usually preferred.

Suits

People supplementing vitamin A or assessing fat-soluble vitamin status with a practitioner.
