What Lab Tests Can Vitamin C Interact With? List 5 And Explain What These Lab Tests Are-
Answer :
1. Urinary test : Benedict's test - Ascorbic acid (Vit. C) is present in urine samples which affects the lab tests for detection of glucose and hemoglobin (Benedict's test). The sample with Vitamin C falsely shows high glucose.
2. Hidden blood tests : Generally conducted for occult (hidden) blood testing. Vitamin C interferes with the test showing negative results for the test.
3. Blood glucose test : Contradictory to the Urinary test, Vitamin C affects the glucose test thorugh blood in exactly opposite way. Low blood glucose level is shown in test even if the blood glucose is high.
4. Vitamin B12 tests : Vitamin C affects Vitamin B12 tests and shows high B12 values even with low B12 diets as B12 serum level is increased. This is called Megadose effect of Vitamin C on Vitamin B12.
5. Interaction with Chemotherapy drugs - As an antioxidant, vitamin C may interfere with the effects of some drugs taken for chemotherapy; however, it is still not clear whether it is useful or harmful to consume Vitamin C with chemotherapy drugs.
