Too much ascorbic acid can result in uncomfortable outcomes such as diarrhea and abdominal cramping. One of the most serious side effects of too much ascorbic acid is kidney troubles, more specifically an increased risk of kidney stones. Increased numbers indicate inflammation or hemorrhage. Unconjugated bilirubin is water soluble and can therefore be excreted in urine. detected in normal urine. A single use of this medicine gives an effect within 24 hours, gradually reducing high blood pressure to normal levels. Bilirubin measures liver function and is usually negative in normal urine specimens. Decreased uric acid levels (<0.24 mmol/L) are commonly seen in patients with SIADH. A single use of this medicine gives an effect within 24 hours, gradually reducing high blood pressure to normal levels. Urine volume varies according to age. Patient should refrain from taking excessive amounts of ascorbic acid or oxalate-rich foods (i.e. Effect of urine pH and ascorbic acid on the rate of conversion of methenamine to formaldehyde. We have to do certain preparations for the Vitamin-C-ascorbic acid test. Normal urine varies from very clear yellow to a darker amber color.
