Understanding Lab Tests for Immunocompromised Conditions
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Immunocompromised conditions occur when the body's immune system is weakened or suppressed, making individuals more susceptible to infections and complications. While there isn't a single blood test to diagnose immunocompromised status itself, blood testing is fundamental for monitoring potential infections that can be particularly dangerous for people with weakened immune systems.
Recommended Test
Cytomegalovirus (CMV) Antibodies, IgG
This test detects IgG antibodies against cytomegalovirus (CMV), which can cause serious health complications in immunocompromised individuals. The presence of CMV IgG antibodies indicates either a current or past infection with this virus, helping healthcare providers assess infection risk and guide appropriate monitoring or treatment strategies for vulnerable patients.

Why Blood Testing is Critical for Immunocompromised Patients
People with compromised immune systems, including those with HIV/AIDS, organ transplant recipients, or individuals undergoing chemotherapy, face increased risks from infections that healthy individuals might easily fight off. Regular blood testing helps detect and monitor these potentially serious infections, enabling prompt treatment and preventing complications.
Who Should Consider This Testing
CMV antibody testing is particularly important for individuals with weakened immune systems, including HIV/AIDS patients, organ transplant recipients, those receiving immunosuppressive medications, and patients undergoing chemotherapy or radiation therapy. Early detection allows for proactive management of potential complications.
