**Overview**: Liver Screen Panel**Introduction**: The Liver Screen Panel is a diagnostic tool designed to screen for liver function using serum samples. In India, asymptomatic liver disease (NAFLD, chronic hepatitis B/C) is common (~10-20 percent adults), often detected late when decompensated. High morbidity from under-screening in rural/low-SES high-risk groups (diabetes, alcohol, viral exposure), limited labs, delayed early intervention leading to cirrhosis/HCC. Per hepatology practices aligned with ICMR and INASL guidelines, the test employs spectrophotometry for 9 liver parameters (ALT, AST, ALP, total/direct bilirubin, albumin, total protein, GGT, globulin) over 1-2 days with high accuracy, valuable as first-line screening for hepatocellular/cholestatic injury or synthetic dysfunction. This diagnostic falls under liver function screening and targets asymptomatic high-risk adults or those with fatigue/jaundice, addressing accurate detection to guide further viral serology, ultrasound, or lifestyle advice. With elevated morbidity due to underdiagnosis, the test supports public health efforts by enabling early liver dysfunction identification and reducing advanced disease burden. Its serum-based approach ensures reliable basic liver profiling.**Other Names**: Liver Scr Pnl.**FDA Status**: FDA approved, CLIA certified for biochemistry, compliant with 2025 standards.**Historical Milestone**: Basic liver screen standard; in India, integrated in NCD programs.**Purpose**: The test assesses 9 parameters including ALT to guide liver function screening, detect injury/synthetic dysfunction, inform further workup.**Test Parameters**: 1. ALT, 2. AST, 3. ALP, 4. Total Bilirubin, 5. Direct Bilirubin, 6. Albumin, 7. Total Protein, 8. GGT, 9. Globulin.**Pretest Condition**: Fasting 10-12 hours recommended; patients should have liver risk factors.**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 alcohol, diabetes, fatigue.**Consent**: Written informed consent is required, detailing the test's purpose, potential risks of undetected liver disease including cirrhosis, 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 medications can affect results. Correlation with clinical evaluation or additional testing is recommended to confirm findings.**Clinical Significance**: Elevated enzymes/bilirubin/low albumin indicate liver dysfunction, necessitating specialist input.**Specialist Consultation**: Hepatologists/gastroenterologists should be consulted for management.**Additional Supporting Tests**: Viral markers, ultrasound for confirmation.**Test Limitations**: Nonspecific; comprehensive approach required.**References**: Indian Journal of Gastroenterology 2024, Liver Studies India 2023. |
