A weakly positive urine test for vitamin C suggests that there may be a high level of vitamin C present in the urine, without any substantial significance, and may be related to increased oral intake or ingestion of vitamin C-related medications. For example, eating too much fruit, or using medications containing vitamin C. Vitamin C is used as a comparative item in urine routine and not as a disease state if it is increased, as increased levels of vitamin C in the urine may lead to false positive results. If there is occult blood as a positive result, or if there is a positive leukocyte esterase and a positive nitrite result. When occult blood is present and there is a positive item such as nitrite, a comparison with vitamin C is required. If vitamin C is also positive, this may result in a local false positive and requires another retest. If the vitamin C is negative, only then is it suggested that there is indeed a practical significance.
