The Lymphocyte Subset Panel 1 measures key immune cell types, including natural killer cells (CD16+CD56), B cells (CD19), and T cells (CD3, CD4, CD8), with both percentages and absolute counts. It also calculates the helper/suppressor (CD4/CD8) ratio. This test helps evaluate immune system function, monitor immune deficiencies, autoimmune diseases, infections, and response to treatment.
The Lymphocyte Subset Panel 4 Test measures CD4+ and CD8+ T-cell percentages and absolute counts, along with the CD4/CD8 ratio and total lymphocyte level. These parameters are vital for evaluating immune function in HIV, immunodeficiency, or therapy response, helping track helper and cytotoxic T-cell balance, immune suppression, and immune recovery.
The IgG Subclasses Panel measures four IgG antibody subclasses (IgG1, IgG2, IgG3, IgG4) to assess immune system function. Abnormal levels may indicate primary immunodeficiency, recurrent infections, autoimmune disease, or allergic conditions. Doctors order this test for patients with chronic sinus, lung, or ear infections or suspected immune imbalance. Results provide key insight into antibody response, guiding diagnosis, treatment, and long-term immune monitoring.
