**Overview**: Pre-Operative Minor Panel**Introduction**: The Pre-Operative Minor Panel is a diagnostic tool designed for pre-operative health screening using serum samples. In India, pre-operative evaluation for minor surgeries (hernia, appendectomy, etc.) is essential to detect anemia, coagulopathy, diabetes, or renal/hepatic dysfunction, reducing perioperative risks. High burden from incomplete screening in rural/low-SES patients undergoing elective procedures, limited labs, delayed correction of abnormalities leading to complications or cancellation. Per anesthesia practices aligned with ICMR and Indian Society of Anaesthesiologists guidelines, the test combines biochemistry (CBC, blood group, PT, APTT, glucose, creatinine, liver enzymes) over 1-2 days with high accuracy, valuable for risk stratification in low-risk surgeries. This diagnostic falls under pre-operative screening and targets patients scheduled for minor procedures, addressing accurate detection to guide optimization or postponement. With elevated burden due to under-screening, the test supports public health efforts by enabling safe surgical planning and reducing complications. Its serum-based approach ensures reliable multi-parameter assessment.**Other Names**: Pre-Op Minor Pnl.**FDA Status**: FDA approved, CLIA certified for radiology/biochemistry, compliant with 2025 standards.**Historical Milestone**: Pre-op panel standard; in India, routine in surgical departments.**Purpose**: The test assesses 7 parameters including CBC to guide pre-operative screening, detect abnormalities, inform anesthesia/surgery.**Test Parameters**: 1. CBC, 2. Blood Group, 3. PT, 4. APTT, 5. Glucose, 6. Creatinine, 7. Liver Enzymes.**Pretest Condition**: Fasting 10-12 hours recommended; patients should be scheduled for minor surgery.**Specimen**: 3 mL serum in 1 SST, transported within specified times to maintain sample viability.**Sample Stability at Room Temperature**: 8 hours with proper handling to preserve analyte integrity, ensuring reliable test performance.**Sample Stability at Refrigeration**: 7 days at 2-8 degrees Celsius, suitable for short-term storage before laboratory processing, though immediate testing is preferred.**Sample Stability at Frozen**: 6 months at -20 degrees Celsius, allowing long-term storage for retesting, though freezing may affect some analytes.**Medical History**: Patients should provide details on prior surgeries, medications.**Consent**: Written informed consent is required, detailing the test's purpose, potential risks of undetected abnormalities including perioperative complications, benefits of screening, and minimal discomfort from venipuncture.**Procedural Considerations**: The test involves sample processing using spectrophotometry by trained personnel to ensure sterile technique, avoid hemolysis, and interpret results within 1-2 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, hemolysis, or non-fasting can affect results. Correlation with clinical evaluation or additional testing is recommended to confirm findings.**Clinical Significance**: Abnormal coagulation/anemia indicates need for correction, necessitating specialist input.**Specialist Consultation**: Anesthesiologists or surgeons should be consulted for management.**Additional Supporting Tests**: ECG, chest X-ray for high-risk cases.**Test Limitations**: Minor surgery-specific; comprehensive approach required.**References**: Indian Journal of Anaesthesia 2024, Pre-op Studies India 2023. |
