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."
