Architect Anti-HCV Regent Kit (100, 500 Test)

The kit is designed to detect immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies to hepatitis C virus (anti-HCV) in human adult serum and plasma, specifically collected with potassium EDTA, lithium heparin, or sodium heparin. This specificity is important because it ensures compatibility with common anticoagulant-preserved samples, allowing laboratories to test a broader range of patient specimens without requiring fresh serum. The ability to test plasma (in addition to serum) expands utility for patients on anticoagulant therapy or those where serum collection is challenging.

The Architect Anti-HCV Regent Kit provides presumptive evidence of past or present exposure to hepatitis C virus (HCV) by detecting antibodies, but it does not determine the state of infection or associated disease. Clinical guidelines recommend confirming results with additional tests (e.g., HCV RNA testing) and correlating findings with patient symptoms, risk factors, and other laboratory data. This is because antibodies may persist after infection resolution, and a negative result does not rule out acute infection.

The kit is supplied as a single-use diagnostic tool and includes reagents, a calibrator, and controls validated exclusively for use on the Abbott Architect i System. Storage and handling instructions are detailed in the reagent package insert, but generally, such immunoassay reagents require refrigeration (typically 2–8°C) and protection from light. Since it is single-use, proper inventory management is critical to avoid expiration, and controls must be used to monitor system precision and detect analytical deviations during operation.

No, the kit is validated for use only on the Abbott Architect i System. Using it on other platforms could yield unreliable or invalid results, as the reagents, calibrator, and controls are specifically designed for this system’s chemiluminescent microparticle immunoassay (CMIA) technology. Incorrect use—such as mixing components from different lots or misapplying the calibrator—may compromise test accuracy and could lead to false positives or negatives, potentially impacting patient management.

The kit is available in two sizes: 100 tests and 500 tests, allowing laboratories to order based on their testing volume and budget. Larger orders (500 tests) may offer cost efficiencies for high-throughput settings, while smaller orders (100 tests) suit lower-volume or satellite labs. Both sizes include all necessary reagents, calibrator, and controls for the specified number of tests, ensuring consistency in performance regardless of order size. Laboratories should verify expiration dates and storage conditions to avoid waste.
