All Immunity and Titer Tests

All Immunity and Titer Tests brings together the blood tests used to document vaccine immunity, check past infection, and screen immune function. Common reasons to test include school or employment requirements, health-care onboarding, travel, proof of hepatitis B response, TB screening before certain medicines, or evaluation of frequent infections.

A proactive plan starts by matching the exact titers you need (MMR, varicella, hepatitis B, tetanus/diphtheria). For past exposure questions, add COVID-19 antibodies (spike ± nucleocapsid). For tuberculosis screening, choose a TB ... See more

The Herpes Simplex Virus 1 and 2 IgG Type-Specific Antibody HerpeSelect® Test detects IgG antibodies to HSV-1 and HSV-2, distinguishing between the two types. A positive result indicates past exposure, as IgG develops weeks after infection and remains long-term. Doctors use this test to confirm herpes diagnosis, guide treatment, or support sexual health decisions. Results provide vital insight into HSV status, infection history, and long-term immune response.

The Total Immunoglobulins Panel measures IgA, IgG, and IgM levels to evaluate immune system function. Abnormal results may indicate immune deficiency, chronic infections, autoimmune disorders, or certain blood cancers. IgA helps protect mucous membranes, IgG provides long-term defense, and IgM is the body’s first response to infection. Doctors use this blood test to diagnose, monitor, and manage immune-related conditions and overall immune health.

The Interleukin 2 Receptor (IL-2R) Test evaluates soluble receptor levels in blood, reflecting immune system activation and regulation. Increased IL-2R may be seen in lymphoma, sarcoidosis, autoimmune conditions, and chronic inflammatory disease. This test provides insights into T-cell activation, immune dysregulation, and disease monitoring, helping guide evaluation of systemic immune health.

The Iron Total and Total Iron Binding Capacity (TIBC) Test measures iron levels in blood along with the blood’s ability to transport iron. It helps diagnose iron deficiency anemia, iron overload (hemochromatosis), and monitor nutritional or chronic health conditions. Low iron or high TIBC may indicate anemia, while high iron or low TIBC can suggest overload. Doctors use this test to evaluate fatigue, weakness, or other symptoms linked to iron and metabolic health.
