Intended Use

The LIAISON® Anti-HAV assay is an in vitro chemiluminescent immunoassay intended for the qualitative detection of total antibodies to hepatitis A (anti-HAV) in human serum and sodium heparin plasma samples using the LIAISON® Analyzer family. The assay is indicated as an aid in the laboratory diagnosis of current or previous HAV infections in conjunction with other serological and clinical information and to determine the presence of an antibody response to HAV in vaccine recipients. This assay is not intended for screening blood or solid or soft tissue donors. Assay performance characteristics have not been established for immunocompromised or immunosuppressed patients. The user is responsible for establishing assay performance characteristics in these populations. Caution: U.S. Federal Law restricts this device to sale by or on the order of a physician. The LIAISON® XL Analyzer is an automated discrete continuous loading chemiluminescent immunoassay (CLIA) analyzer for in vitro diagnostic analysis of CLIAs on human serum or plasma. The system menu includes infectious disease, bone and mineral, and endocrinology CLIAs. It is to be used only with FDA cleared chemilyminescence immunoassays that are marketed by DiaSorin for the LIAISON XL Analyzer. The LIAISON® Control Anti-HAV (negative and positive) is intended for use as assayed quality control samples to monitor the performance of the LIAISON® Anti-HAV assay. The performance characteristics of LIAISON® controls have not been established for any other assays or instrument platforms different from LIAISON® and LIAISON® XL.

Device Story

LIAISON® XL Analyzer is an automated, floor-standing, continuous-loading chemiluminescent immunoassay (CLIA) system for clinical laboratory use. It processes human serum or plasma samples to detect infectious disease, bone/mineral, and endocrinology markers. Input samples are processed via disposable tips; reagent levels are tracked via RF-ID technology. The system uses magnetic particle solid-phase technology and isoluminol-antibody conjugates. A competitive sandwich immunoassay principle is employed: anti-HAV in samples competes with conjugate for fixed HAV; light signal (RLU) measured by photomultiplier tube is inversely proportional to anti-HAV concentration. The system features automated pipetting, incubation, wash cycles, and data reduction. Results are displayed via touch-screen interface for physician review to aid clinical diagnosis. Benefits include increased throughput, automated maintenance, and improved resource management compared to the predicate LIAISON® Analyzer.

Clinical Evidence

No clinical data provided; substantial equivalence is based on bench testing and performance comparisons between the LIAISON® XL and the predicate LIAISON® Analyzer.

Technological Characteristics

Automated CLIA analyzer; magnetic particle solid-phase; photomultiplier tube (PMT) optical system (450 nm emission); 36°C reaction temperature; RF-ID reagent tracking; disposable sample tips; continuous loading; touch-screen interface; LIS connectivity.

Indications for Use

Indicated for qualitative detection of total anti-HAV antibodies in human serum and sodium heparin plasma. Used as an aid in diagnosing current or previous HAV infection and assessing vaccine response. Not for blood/tissue donor screening. Performance not established for immunocompromised/immunosuppressed patients.

Regulatory Classification

Identification

HAV serological assays are devices that consist of antigens and antisera for the detection of hepatitis A virus-specific IgM, IgG, or total antibodies (IgM and IgG), in human serum or plasma. These devices are used for testing specimens from individuals who have signs and symptoms consistent with acute hepatitis to determine if an individual has been previously infected with HAV, or as an aid to identify HAV-susceptible individuals. The detection of these antibodies aids in the clinical laboratory diagnosis of an acute or past infection by HAV in conjunction with other clinical laboratory findings. These devices are not intended for screening blood or solid or soft tissue donors.

Special Controls

*Classification.* Class II (special controls). The special control is “Guidance for Industry and FDA Staff: Class II Special Controls Guidance Document: Hepatitis A Virus Serological Assays.” See § 866.1(e) for the availability of this guidance document.

The system menu includes infectious disease, bone and mineral, and endocrinology CLIAs. It is to be used only with FDA cleared chemiluminescence immunoassays that are marketed by DiaSorin for the LIAISON XL Analyzer. The LIAISON® Control Anti-HAV (negative and positive) is intended for use as assayed quality control samples to monitor the performance of the LIAISON® Anti-HAV assay. The performance characteristics of LIAISON® controls have not been established for any other assays or instrument platforms different from LIAISON® and LIAISON® XL. ## DESCRIPTION: The method for qualitative determination of anti-HAV is a competitive sandwich chemiluminescence immunoassay (CLIA) based on neutralization. Antibodies to HAV (mouse monoclonal) are used for coating magnetic particles (solid phase) and are linked to an isoluminol derivative (isoluminol-antibody conjugate). During the first incubation, anti-HAV present in calibrators, samples or controls binds to a fixed and limited amount of HAV, thus forming an HAV-anti-HAV immune complex. During the second incubation, the antibody conjugate and the solid-phase antibody compete with anti-HAV present in the specimen for HAV, that allows the conjugate to bind to the solid phase and thus form a "sandwich" of conjugate antibody-antigen-solid phase antibody. If all HAV added is sequestered in an HAVanti-HAV immune complex during the first incubation, no sandwich is formed during the second incubation. After the second incubation, the unbound material is removed with a wash cycle. Subsequently, the starter reagents are added and a flash chemiluminescence reaction is thus induced. The light signal, and hence the amount of isoluminolantibody conjugate, is measured by a photomultiplier as relative light units (RLU) and is inversely indicative of anti-HAV present in calibrators, samples or controls The LIAISON® XL Analyzer is an automated discrete continuous loading chemiluminescent immunoassay analyzer for in vitro diagnostic use. {2}------------------------------------------------ .
