IMMUNOGLOBULIN PROFILE (SERUM)

The IMMUNOGLOBULIN PROFILE (SERUM) is a blood test that measures the concentrations of key antibodies (immunoglobulins) in serum—primarily IgG, IgA, IgM and IgE, with optional assessment of IgG subclasses—providing a direct assessment of humoral immune function. The test is performed on a venous blood sample and helps identify immune deficiencies, quantify allergic markers, evaluate vaccine response, and monitor the effect of immunoglobulin replacement or biologic therapies. Available as a convenient at‑home service across Dubai, the profile is processed in accredited UAE laboratories and reported with clinical reference ranges to guide further specialist care. Results should be interpreted by a physician or immunologist to determine diagnosis and treatment planning, including need for further immunological workup.

This profile is recommended for individuals with recurrent or severe infections, poor or waning response to vaccinations, suspected primary or secondary immunodeficiencies, or as part of allergy and autoimmune evaluations. It is also useful as a baseline before starting immunosuppressive or biologic drugs and for monitoring patients receiving IVIG or other antibody therapies. Because immunoglobulin levels can be affected by recent treatments and acute illness, timing and clinical context are important—your Touch Connect phlebotomist and reporting lab will note relevant factors for your clinician.

For accurate testing, a standard venous blood draw is required and fasting is generally not necessary; however, inform the collector if you have recently received IVIG, monoclonal antibodies, blood transfusions, or vaccinations, as these can alter results. Reported results typically use g/L or mg/dL units and may include interpretive comments; abnormal findings often prompt additional tests (e.g., vaccine-specific antibody titers, lymphocyte subsets, serum protein electrophoresis) or referral to a specialist in Dubai for tailored management.
