Summary
A simple tablet test accurately detects microalbuminuria, an early sign of diabetic kidney disease. This cost-effective screening method is suitable for widespread use in diagnosing kidney complications.
Area of Science:
- Nephrology
- Diabetology
- Clinical Chemistry
Background:
- Diabetes mellitus is a leading cause of chronic kidney disease.
- Albuminuria, particularly microalbuminuria, is an early indicator of diabetic nephropathy.
- Early detection of microalbuminuria is crucial for timely intervention and management.
Purpose of the Study:
- To evaluate the diagnostic accuracy of a simple qualitative tablet test for microalbuminuria.
- To compare the performance of the tablet test against a quantitative immunoturbidometric method.
Main Methods:
- A qualitative tablet test utilizing bromphenol blue was compared with a quantitative immunoturbidometric assay.
- 109 urine samples were analyzed using both methods.
Main Results:
- The tablet test demonstrated high sensitivity (93.5%) and specificity (94.0%) for detecting microalbuminuria.
- Positive and negative predictive values were 87.9% and 97.4%, respectively.
- The test showed a low false positive rate (5.2%) and false negative rate (6.2%).
Conclusions:
- The bromphenol blue tablet test is a simple, accurate, and reliable method for detecting microalbuminuria.
- This test is well-suited for mass population screening and individual diagnosis of early diabetic kidney disease.
