"I simply ordered the test online, received it in the mail a few days later, and took the test in the comfort of my own home using a quick finger prick. The instructions were clear and easy to follow, and the process itself was quick and painless."

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.

Expert’s Opinion

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."
