Description

Clinical Utility: The CMV inSIGHT™ T Cell Immunity Panel measures the strength of T cell responses to Cytomegalovirus (CMV) specific antigens. It evaluates and reports the activity of CD4 and CD8 T cell responses independently. Effective T cell immunity against CMV is a factor in controlling CMV viral latency. CMV can affect patients with weakened immune systems and is a common risk factor in patients following solid organ or hematopoietic stem cell transplant.

Approval: Laboratory Medicine Resident (LMR) or Micro Fellow approval is required.

***Collection Note: Samples must be shipped to Eurofins the same day as collection. Blood draws should be appropriately timed to ensure arrival at UW-MT SPS by 13:00 for same-day shipment. Highly recommend collection at UW-MT to eliminate delays. Samples collected at at UW-NW or HMC should be collected prior to 10:00 a.m. with sample in lab by 11:00 a.m. Testing cannot be guaranteed for specimens received after that time.***

Components

Interpretation

Method

Whole blood is stimulated with SEB, CMV antigens, or left unstimulated as a negative control and incubated at 37ºC. During the incubation Brefeldin A is added, causing the interferon (IFN)-gamma to be retained inside the cell. Following the stimulation phase, cells are recovered, stained for surface markers (CD45, CD3,CD4, CD8, CD69) and intracellular IFN-gamma, and analyzed by flow cytometry. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
