Introduction
Vitamin C is a water-soluble vitamin, also known as ascorbic acid or vitamin C. It is excreted through the kidneys, so normal urine contains vitamin C. Whether a urinary vitamin C level of 0.6 mmol/L is normal depends on specific circumstances. If caused by physiological factors, it is considered normal; if caused by pathological factors, it is considered abnormal.
Whether a urinary vitamin C level of 0.6 mmol/L is normal depends on the specific circumstances. If elevated due to physiological reasons, it is considered normal; if caused by pathological factors, it is considered abnormal. The detailed analysis is as follows:
1. Normal
Urinalysis includes a test for vitamin C. Under normal conditions, vitamin C should be negative. A slightly elevated level of vitamin C in urine generally has no significant clinical implications and does not greatly affect health. Elevated vitamin C levels are often related to daily diet. Consuming foods rich in vitamin C may lead to higher detected levels during urinalysis. Vitamin C acts as an interfering substance and may cause false-positive results in certain urine tests—for example, in nitrite or occult blood testing—potentially leading to inaccurate test outcomes.
2. Abnormal
If kidney diseases such as pyelonephritis or glomerulonephritis are present, the filtration function of metabolic substances may be impaired, potentially leading to elevated urinary vitamin C levels. Without treatment, excessive vitamin C may increase oxalate production in the body, which can crystallize in the kidneys and trigger kidney stone formation, thereby worsening existing kidney conditions. It is recommended to visit a reputable hospital for further evaluation to identify the underlying cause and receive appropriate medical treatment to prevent disease progression.
Vitamin C is a water-soluble vitamin, also known as ascorbic acid or vitamin C. It is excreted through the kidneys, so normal urine contains some vitamin C. The normal reference range is generally 0.285–0.741 mmol/L (may vary slightly depending on the testing method).
