Immunosuppression

The symptoms vary with the specific disorder.

Your doctor might think you have an immunodeficiency disorder if you have:

• Persistent, recurrent infections
• Severe infection by microorganisms that do not usually cause severe infection

Other signs include:

• Poor response to treatment for infections
• Delayed or incomplete recovery from illness
• Certain types of cancers (such as Kaposi's sarcoma or non-Hodgkin's lymphoma)
• Certain infections (including some forms of pneumonia or recurrent yeast infections)

Tests used to help diagnose an immunodeficiency disorder may include:

• Complement levels in the blood, or other tests to measure substances released by the immune system
• Immunoglobulin levels in the blood
• Protein electrophoresis (blood or urine)
• T (thymus derived) lymphocyte count
• White blood cell count
