Learn how false positives are ruled out. Call (877) 731-6362. --- Hepatitis panel accuracy relies on certified laboratory methods, including initial screening and confirmatory testing, with every non-negative result reviewed by a Medical Review Officer to rule out false positives. Testing is conducted through five national lab networks. Call (877) 731-6362 for more information. OVERVIEW ## What determines hepatitis panel accuracy? Hepatitis panel accuracy depends on the use of certified laboratory methodologies and a two-step testing process. The initial screen detects potential infection markers, while confirmatory tests validate positive results to ensure reliability. Cutoff levels established by national standards minimize false positives and negatives, contributing to precise outcomes. Initial screening identifies possible hepatitis markers using sensitive assays. Confirmatory testing verifies positive screens with more specific methods. Cutoff levels are set to balance sensitivity and specificity. Testing is performed at nationally certified labs to ensure quality. LAB NETWORKS ## Which labs handle hepatitis panel testing? AMH Nationwide routes hepatitis panel specimens through five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. This multi-lab approach ensures access to certified facilities with standardized protocols that uphold testing accuracy. Quest Diagnostics LabCorp Omega Labs United States Drug Testing Labs ExperTox TESTING PROCESS ## How do initial screening and confirmatory tests differ? The initial hepatitis panel screen uses sensitive immunoassays to detect antibodies or antigens indicative of infection. Positive or equivocal results trigger confirmatory testing, often with nucleic acid amplification or supplemental serologic assays, which are more specific and rule out false positives caused by cross-reactivity or technical issues. Initial Screen: Highly sensitive, designed to detect any markers of hepatitis infection. Confirmatory Test: More specific, used to verify initial positives and exclude false positives. CUT-OFF LEVELS ## What role do cutoff levels play in hepatitis panel accuracy? Cutoff levels define the threshold between negative and reactive results in hepatitis panel testing. These levels are determined based on extensive validation studies and regulatory guidelines to optimize test sensitivity while minimizing false positives. Adjusting cutoff values improperly can compromise accuracy and lead to incorrect diagnoses. ## Ensure Accurate Hepatitis Panel Testing For reliable hepatitis panel accuracy using certified labs and expert review, contact AMH Nationwide.

Every non-negative hepatitis panel result undergoes review by a certified Medical Review Officer (MRO). The MRO evaluates laboratory data alongside clinical information to confirm or refute positive findings. This step helps identify false positives caused by medications, vaccinations, or other factors, ensuring accurate interpretation before reporting results. FALSE POSITIVES ## How are false positives ruled out in hepatitis panel testing? False positives in hepatitis panel testing are minimized through confirmatory assays with higher specificity and MRO review. Confirmatory tests detect viral RNA or specific antibodies, which reduces cross-reactivity. The MRO assesses patient history and potential interfering factors to prevent misclassification and unnecessary concern. Confirmatory testing targets specific viral markers. MRO considers clinical context and potential cross-reactivity. Use of nationally certified labs ensures adherence to protocols.

It screens for current or past infection and immunity status. Confirmatory testing verifies initial positive results to eliminate false positives caused by cross-reactivity or technical errors, ensuring accurate diagnosis. Turnaround times vary by lab network and test type but generally range from 1 to 5 business days after specimen collection. No. AMH Nationwide provides lab orders and directs requesters to collection sites but does not offer online ordering. Call (877) 731-6362 to begin. Yes. Every non-negative result is reviewed by a certified Medical Review Officer to confirm accuracy and rule out false positives.
