Mineral Panel Test
Your doctor may recommend a blood test to check for a vitamin A deficiency. The test measures the level of a protein called retinol-binding protein (RBP). RBP is involved in the absorption of vitamin A from food. Low levels of RBP can be a sign of a vitamin A deficiency. Your doctor may also recommend other tests, such as a liver function test, to check for problems with your liver. This organ stores vitamin A.
Treatment for vitamin a deficiency
If you have a vitamin A deficiency, your doctor will likely recommend that you take a supplement. You may also need to eat more foods that are rich in vitamin A, such as carrots, sweet potatoes, and squash. In severe cases, you may need to receive injections of vitamin A.
Prevention of vitamin a deficiency
You can help prevent a vitamin A deficiency by eating a balanced diet that includes plenty of fruits and vegetables. If you're at risk for a deficiency, your doctor may recommend that you take a supplement.

Experts Opinion on Vitamin A Tests
"As a doctor, we use this test to check your vitamin A levels so that you can either top up and optimise your levels as necessary or, maintain what you’re doing if it's adequate. This test can also be used to ensure your levels aren't too high, as vitamin A can cause toxicity levels on higher intake doses."
