**Overview**: Allergy 5 Allergens Panel**Introduction**: The Allergy 5 Allergens Panel is a diagnostic tool designed to screen for selected allergens using serum samples. In India, customized allergen mixes are increasingly used for targeted screening in patients with suspected poly-allergy, where sensitization to common triggers (dust mite, pollen, mold, food) is high (20-70 percent in symptomatic cohorts). This panel allows for tailored testing based on regional or patient-specific exposures. Symptoms vary by allergen but include rhinitis, asthma exacerbations, urticaria, or gastrointestinal issues. High morbidity from underdiagnosis in multi-allergen exposed individuals, limited access to full panels in resource-limited labs, and delayed management. Per immunology practices aligned with ICMR guidelines, the test employs immunoassay for custom 5-allergen mix analysis over 1-2 days with high sensitivity/specificity, valuable as a focused screening tool. This diagnostic falls under allergy screening and targets individuals with suspected allergies to specific groups, addressing accurate detection to guide further testing and treatment. With morbidity elevated due to underdiagnosis in diverse populations, the test supports public health efforts by enabling precise identification, facilitating management, and reducing chronic burden. Its serum-based approach ensures reliable detection.**Other Names**: 5 Allergens Pnl.**FDA Status**: FDA approved, CLIA certified for immunology, compliant with 2025 standards.**Historical Milestone**: Developed for customized screening; in India, adopted for patient-specific allergen profiles.**Purpose**: The test screens for 1 parameter (custom 5 allergen IgE mix) to guide assessment, identify atopy to selected triggers, and inform specific management.**Test Parameters**: 1. Custom 5 Allergen IgE Mix.**Pretest Condition**: No fasting required; patients should report symptoms potentially linked to suspected allergens.**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 symptoms, suspected triggers, environmental/dietary exposures, family atopy.**Consent**: Written informed consent is required, detailing the test's purpose, potential risks of untreated allergies, benefits of early detection, and minimal discomfort from venipuncture.**Procedural Considerations**: The test involves sample processing using immunoassay 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, and store kits according to manufacturer specifications to ensure reliability.**Factors Affecting Result Accuracy**: Delays beyond stability periods, improper storage conditions, hemolysis, or cross-reactivity can affect results. Correlation with clinical evaluation or additional testing is recommended to confirm findings.**Clinical Significance**: Abnormal results indicate possible sensitization to the custom mix, necessitating further investigation like specialist consultation or specific allergen testing. Normal results may require follow-up if symptoms persist.**Specialist Consultation**: Allergists should be consulted for case management, treatment planning, and coordination with health programs.**Additional Supporting Tests**: Specific IgE panels or skin prick tests for confirmation.**Test Limitations**: The test may produce false negatives in low exposure or false positives in asymptomatic sensitization, requiring a comprehensive diagnostic approach that includes clinical correlation.**References**: ICMR Allergy Guidelines 2023, Indian Journal of Allergy Asthma Immunology 2024. |
