Description
Why It’s Done:
• To diagnose ZAP-70 deficiency, which causes severe combined immunodeficiency (SCID), a condition where the immune system is severely compromised, leaving individuals vulnerable to infections.
• To help identify abnormalities in T-cell function and immune signaling.
• To assist in diagnosing immune system disorders in patients who exhibit recurrent infections or other symptoms related to immune dysfunction.
Preparation:
• No special preparation is generally needed, but it is important to follow any instructions provided by your healthcare provider. The test usually involves drawing a blood sample, so being well-hydrated can be helpful.
