ANATOMY

Detailed explanation-1: -Normal urine contains uric acid.

Detailed explanation-2: -Normal Results Normal values range from 250 to 750 mg/24 hours (1.48 to 4.43 mmol/24 hours). Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples.

Detailed explanation-3: -Human urine is composed primarily of water (95%). The rest is urea (2%), creatinine (0.1%), uric acid (0.03%), chloride, sodium, potassium, sulphate, ammonium, phosphate and other ions and molecules in lesser amounts30 (Table 1). Protein is only found in trace amounts compared to their values in blood plasma.

Detailed explanation-4: -A normal urea level in the urine is 12 to 20 grams over 24 hours. Individual labs may have reference ranges that vary slightly and can be different based on sex or age. Low levels of urea in the urine may suggest: malnutrition.

Detailed explanation-5: -Urine is an aqueous solution of greater than 95% water, with a minimum of these remaining constituents, in order of decreasing concentration: Urea 9.3 g/L. Chloride 1.87 g/L. Sodium 1.17 g/L.
