"What Are the Three Key Indicators to Fear in Urinalysis?"

Three Key Indicators in Urine Routine Examination

There is generally no such statement as "the three most feared indicators in urine routine examination." In urine routine tests, physicians typically focus on indicators such as urine protein, urine glucose, and occult blood/red blood cells in urine to ensure patients' health status. Here are the details:

1. Urine Protein

Urine protein is a crucial indicator for assessing renal function. The detection of urine protein, especially if persistent, in urine routine tests may indicate kidney problems. The presence of urine protein can be an early sign of diseases such as glomerulonephritis and nephrotic syndrome. Normally, urine should not contain large amounts of protein. If urine protein is present, further renal function tests and specialist reviews are recommended.

2. Urine Glucose

Elevated urine glucose levels may be associated with diabetes. In fasting conditions, if urine glucose exceeds 7.1 (note: this is a possible reference range and specific values may vary depending on the detection method or standard), it may indicate a risk of diabetes. High urine glucose can also be related to factors such as diet and medication use, but persistent high urine glucose requires further investigation to determine the cause.

3. Occult Blood/Red Blood Cells in Urine

Occult blood and red blood cells in urine are indicators of blood presence in urine. A positive occult blood test, especially if persistent over a long period (e.g., more than three times), or accompanied by an increase in red blood cells, may indicate urinary system diseases such as urinary tract infections, stones, or nephritis. The presence of occult blood and red blood cells in urine warrants attention and may require further investigation to determine the underlying cause.

If any abnormal indicators are found in urine routine examination, it is recommended to seek medical attention promptly for further examination and treatment. Additionally, maintaining good lifestyle and dietary habits, avoiding excessive fatigue and unhealthy practices, can help prevent the occurrence of urinary system diseases.
