|Test Principle||2013||The QuantiFERON-CMV assay is an in vitro research test that detects CD8+ T cell immunity to human cytomegalovirus infection (HCMV). It uses human whole blood, with patented assay technology based on the measurement of Interferon-gamma (IFN-ɣ) secreted from stimulated T-cells previously exposed to HCMV. The QuantiFERON-CMV assay is a straightforward laboratory test that involves 4 simple steps: 1. Collection of blood into QuantiFERON-CMV Blood Collection Tubes. 2. Overnight incubation at 37°C. HMCV infected patients' blood cells will produce IFN-ɣ 3. Detection of released IFN-ɣ in harvested plasma using a quick and easy ELISA. 4. Analysis of data using the QuantiFERON-CMV Analysis Software. Some of the Frequently Asked Questions relating to the assay are listed below. The answers provided act as a guide only. We recommend that the QuantiFERON-CMV Package Insert be used as the reference for the test procedure, as well as for other enquiries relating to the use or performance of the assay.|
