What This Test Measures
The test detects specific antibodies or other immune response indicators in your serum or plasma that signal recent infection. It may involve measuring substances like cytokines, chemokines, or other biomarkers associated with immune activation.
Why It’s Ordered
Your healthcare provider may order this test if you’ve been exposed to an infectious disease, show symptoms of infection, or if you’re in a setting where isolation precautions are necessary (e.g., hospitals, long-term care facilities).
What to Expect
A blood sample is drawn from a vein in your arm. The sample is then tested in a lab using an immunoassay method to detect infection-related substances. Results are typically available within a few days.
Common Causes for Testing
This test is often used for conditions like tuberculosis, respiratory infections, or other contagious illnesses where isolation is critical. It helps healthcare teams manage patient care safely.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results indicate an active infection that may require isolation to prevent spreading germs to others. Negative results suggest no recent infection detected, but further testing may still be needed if symptoms persist. This test is not diagnostic for all infections and may not detect every possible pathogen.
