Urine appearance (transparency, turbidity, Clarity, CLA)
Urine transparency and turbidity are evaluated by measuring the transmission of light. Normally, freshly voided urine is transparent.
When allowed to stand for long periods of time, urine becomes cloudy due to the precipitation of salts and other components. This is normal and has no diagnostic value. Therefore, deliver your urine to the laboratory within an hour after collecting it. Otherwise, your urine test results may be inaccurate.
Highly turbid urine may be due to erythrocytes, leukocytes, bacteria, epithelium, mucus, fats and various salts (urates, phosphates, oxalates) in your urine.
Occasionally turbid urine is not always a symptom of some disease. Turbid urine may be caused by not drinking enough water. However, consult your doctor if your urine has been turbid for a long period of time.
