Overview: Urine Routine Examination Automated Panel
Introduction: The Urine Routine Examination Automated Panel is a diagnostic tool designed for general health screening using urine samples. In India, urinary tract infections (UTIs) affect ~150 million cases/year (higher in women, rural/low-SES due to poor sanitation/hygiene), with asymptomatic bacteriuria common in pregnancy/diabetes and proteinuria/crystals indicating kidney disease or metabolic issues. High morbidity from under-testing leading to delayed antibiotics or renal evaluation, causing recurrent UTIs, pyelonephritis, or chronic kidney disease progression. Per clinical pathology practices aligned with ICMR and Indian Society of Nephrology guidelines, the test employs automated spectrophotometry/microscopy for 38 parameters (color, appearance, pH, specific gravity, glucose, protein, ketones, bilirubin, urobilinogen, nitrite, leukocyte esterase, RBC/WBC, epithelial cells, casts, crystals, bacteria, yeast, mucus, pus cells, various casts/crystals, etc.) over 1â€"2 days with high accuracy, valuable for rapid UTI screening, diabetes monitoring, and renal stone risk assessment. This diagnostic falls under urinalysis and targets patients with dysuria, fever, diabetes, pregnancy, or routine check-up, addressing accurate detection to guide antibiotics, hydration, or further renal workup. With elevated morbidity due to underdiagnosis, the test supports public health efforts by enabling affordable urine profiling and reducing UTI/renal burden. Its urine-based approach ensures reliable automated multi-parameter evaluation.
Other Names: Urine RE Auto Pnl.
FDA Status: FDA approved, CLIA certified for biochemistry/clinical pathology, compliant with 2025 standards.
Historical Milestone: Automated urine analyzers standard in labs; in India, widely used in primary/antenatal care.
Purpose: The test assesses 38 parameters including color and glucose to guide general health screening, detect UTI/metabolic/renal issues, inform therapy.
Test Parameters: 1. Color, 2. Appearance, 3. pH, 4. Specific Gravity, 5. Glucose, 6. Protein, 7. Ketones, 8. Bilirubin, 9. Urobilinogen, 10. Nitrite, 11. Leukocyte Esterase, 12. RBC, 13. WBC, 14. Epithelial Cells, 15. Casts, 16. Crystals, 17. Bacteria, 18. Yeast, 19. Mucus, 20. Amorphous Material, 21. Pus Cells, 22. Hyaline Casts, 23. Granular Casts, 24. RBC Casts, 25. WBC Casts, 26.

Parasites, 35. Blood, 36. Albumin, 37. Sugar, 38. Volume.
Pretest Condition: No fasting required; patients should provide midstream urine.
Specimen: 10 mL urine in sterile container, transported within specified times to maintain sample viability.
Sample Stability at Room Temperature: 2 hours with proper handling to preserve cellular elements, ensuring reliable test performance.
Sample Stability at Refrigeration: 24 hours at 2-8 degrees Celsius, suitable for short-term storage before laboratory processing, though immediate testing is preferred.
Sample Stability at Frozen: Not frozen (fresh sample preferred for microscopy).
Medical History: Patients should provide details on dysuria, diabetes, pregnancy.
Consent: Written informed consent is required, detailing the test's purpose, potential risks of undetected UTI/renal issue including progression, benefits of screening, and minimal discomfort from urine collection.
Procedural Considerations: The test involves sample processing using automated spectrophotometry/microscopy by trained personnel to ensure sterile technique and interpret results within 1â€"2 days using provided controls. Laboratories must maintain a controlled environment, adhere to quality assurance protocols.
Factors Affecting Result Accuracy: Delays beyond stability periods, improper storage conditions, or contamination can affect results. Correlation with clinical evaluation or additional testing is recommended to confirm findings.
Clinical Significance: Positive nitrite/leukocyte esterase indicates UTI; proteinuria/glucose suggests diabetes/renal disease, necessitating specialist input.
Specialist Consultation: Nephrologists or general physicians should be consulted for management.
Additional Supporting Tests: Urine culture, renal function tests for confirmation.
Test Limitations: Automated systems may miss rare elements; comprehensive approach required.
