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 Total T and B Cells Test measures levels of T lymphocytes and B lymphocytes, key white blood cells essential for immune defense. Abnormal counts may indicate immune deficiencies, autoimmune disorders, infections, or blood cancers. Doctors use this test to evaluate immune system function, diagnose underlying conditions, and monitor treatment. It is often ordered with other immune panels to provide a comprehensive view of adaptive immunity.

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.

The Fusarium Proliferatum/Moniliforme IgG Test is a specialized immunological assay designed to detect IgG antibodies against Fusarium proliferatum and Fusarium moniliforme in the blood. Fusarium species are fungi that can be found in soil, plants, and air, and are known to produce mycotoxins that can be harmful to humans and animals. While Fusarium infections are relatively rare in humans, they can occur, especially in immunocompromised individuals, leading to conditions ranging from localized infections to more severe systemic diseases.

The Absolute Lymphocyte Count Test quantifies lymphocytes in blood, expressing immunity status through an absolute cell count rather than relative percentage. It aids in diagnosing immune disorders, tracking viral infection recovery, or identifying early signs of hematologic disease. By distinguishing lymphocytosis and lymphopenia, this test provides clinicians insight into immune suppression, overactivation, or recovery phases in infections or immunocompromised states.

The Herpes Virus 6 IgG IgM Antibodies Test detects immune response to HHV-6, a virus linked to roseola and other illnesses. IgM antibodies suggest recent or acute infection, while IgG indicates past exposure or reactivation. This test supports evaluation of fever, rash, or neurologic symptoms and may help identify complications in immunocompromised patients, providing valuable insight into HHV-6 infection status and immune activity.

The Quantitative Epstein-Barr Virus (EBV) DNA Real-Time PCR Test measures the amount of EBV genetic material in blood to monitor viral load. Unlike antibody tests, it directly tracks EBV activity, making it vital for transplant patients, immunocompromised individuals, or those with chronic EBV. Doctors order this test to evaluate risk of complications, guide treatment, and monitor response to therapy by quantifying EBV levels over time.

The Cytomegalovirus (CMV) IgG IgM Antibodies Test detects both recent and past infection with CMV, a common herpesvirus. IgM indicates recent or active infection, while IgG shows past exposure and possible immunity. Doctors order this test for pregnant women, immunocompromised patients, or those with unexplained fever or fatigue. Results help diagnose CMV, guide treatment, and assess risk of complications such as congenital infection or organ damage.

The Chemistry Panel (Comprehensive Metabolic Panel) measures 21 biochemical markers—electrolytes, glucose, liver enzymes, proteins, BUN, creatinine—to assess kidney and liver function, acid-base balance, and metabolic status. This integrated test offers clinicians a broad snapshot of organ health, metabolic balance, and potential dysfunction.

 The Hepatic Panel is a comprehensive set of blood tests designed to evaluate the function of the liver. This panel measures various enzymes, proteins, and substances in the blood that are either produced by the liver or released when liver cells are damaged. It provides crucial information about the liver's condition, aiding in the diagnosis, monitoring, and differentiation of liver disorders.
