Immunodeficiency conditions involve a weakened or compromised immune system that cannot effectively fight infections and diseases. These conditions are caused by primary genetic defects present from birth or secondary factors like HIV/AIDS, immunosuppressive medications, chemotherapy, or organ transplantation. The Toxoplasma Antibody (IgG) test is the most important test for monitoring opportunistic infection risk in immunocompromised individuals.

Immunodeficiency conditions are caused by either primary genetic defects present from birth or secondary factors that weaken the immune system later in life. Primary immunodeficiencies result from inherited mutations affecting immune cell development or function, while secondary immunodeficiencies develop from HIV/AIDS infection, cancer treatments like chemotherapy and radiation, immunosuppressive medications used after organ transplants, chronic diseases like diabetes, or severe malnutrition. These factors damage or suppress the production and function of white blood cells, antibodies, and other immune system components that normally protect against infections.
The Toxoplasma Antibody (IgG) test is the most important test for monitoring immunodeficiency conditions because it detects antibodies against Toxoplasma gondii, a parasite that causes serious complications in people with weakened immune systems. This test helps assess your body's ability to produce protective antibodies and identifies infection risk from opportunistic pathogens. While immunocompromised individuals may have difficulty producing detectable antibodies, this test remains essential for monitoring immune response capabilities, especially for those with HIV/AIDS or following organ transplantation. Additional tests like complete blood counts with differential, immunoglobulin levels, and CD4 T-cell counts help provide a comprehensive picture of immune system function.
You should get tested if you experience frequent infections that keep coming back, infections that are unusually severe or difficult to treat, or infections from organisms that rarely cause problems in healthy people. Get tested if you have been diagnosed with HIV/AIDS, are taking immunosuppressive medications after an organ transplant, are undergoing chemotherapy or radiation treatment, or have unexplained weight loss and chronic fatigue along with recurrent infections. Testing is also important if you have a family history of primary immunodeficiency or if your doctor suspects your immune system is not functioning properly based on your symptoms and medical history.

What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
