Intended Use

The DPC IMMULITE 2500 analyzer is an automated immunoassay system intended to assay the same broad range of analytes in patient samples as does IMMULITE 2000. The intent of the system is to impart the same automation to the same array of immunoassays in the same hospital and commercial laboratory settings as IMMULITE 2000. Examples of the array of assays to be used with the DPC IMMULITE 2500 are two for which data in support of a claim of substantial equivalence have been submitted to FDA: hCG (product code: DHA) and TSH (JLW). The system is intended to produce safe and effective performance when used by medical laboratory personnel as is the predicate system, IMMULITE 2000.

Device Story

Automated immunoassay analyzer; processes patient samples to measure various analytes. Uses 1/4 inch polystyrene antibody-coated beads and alkaline phosphatase-labeled antibodies/antigens. Chemiluminescent detection system employs phosphate ester stabilized dioxetane; cleavage by alkaline phosphatase triggers photon emission. Luminometer quantifies photons; output proportional to analyte concentration. Operated by medical laboratory personnel in hospital or commercial laboratory settings. Results assist clinicians in diagnostic decision-making. Provides automated workflow for high-throughput immunoassay testing.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by bench testing and performance data for specific assays (hCG and TSH) demonstrating equivalent performance to the predicate IMMULITE 2000 system.

Technological Characteristics

Automated immunoassay analyzer. Materials: 1/4 inch polystyrene antibody-coated beads. Detection: Chemiluminescent system using phosphate ester stabilized dioxetane and alkaline phosphatase. Sensing: Luminometer for photon quantification. Connectivity: Automated system for laboratory use.

Indications for Use

Indicated for use by medical laboratory personnel in hospital and commercial laboratory settings to perform automated immunoassays on patient samples for a broad range of analytes, including hCG and TSH.

Regulatory Classification

Identification

A human chorionic gonadotropin (HCG) test system is a device intended for the early detection of pregnancy is intended to measure HCG, a placental hormone, in plasma or urine. A human chorionic goadotropin (HCG) test system is a device intended for any uses other than early detection of pregnancy (such as an aid in the diagnosis, prognosis, and management of treatment of persons with certain tumors or carcinomas) is intended to measure HCG, a placental hormone, in plasma or urine.

### Intended Use of the Device:

These modifications do not change the indications for use, nor the intended use from the IMMULITE 2000 to the IMMULITE 2500. The IMMULITE 2500 analyzer is an automated immunoassay system intended to assay the same broad range of analytes in patient samples as does IMMULITE 2000. The intent of the system is to impart the same automation to the same array of immunoassays in the same hospital and commercial laboratory settings as IMMULITE 2000. The system is intended to produce safe and effective performance when used by medical laboratory personnel as is the predicate system, IMMULITE 2000.

### Technology:

The IMMULITE 2500 uses ¼ inch polystyrene antibody coated beads and assay specific antibody or antigen labeled with alkaline phosphatase. The chemiluminescent detection system is a phosphate ester stabilized dioxetane. Cleavage of the phosphate ester by alkaline phosphatase results in the decomposition of the dioxetane and the emission of photons, which are quantified by a luminometer and are proportional to the quantity of analyte present.

### Conclusion:

The data presented in this summary of safety and effectiveness is the data that the Food and Drug Administration used in granting DPC substantial equivalence for the IMMULITE 2500 Automated Immunoassay Analyzer.
