Genetic testing for immunodeficiency

Genetic testing for immunodeficiency involves analyzing a person’s DNA to identify mutations or changes in specific genes that affect the immune system. These genetic alterations can cause immunodeficiency, where the immune system is weaker or functions improperly, leading to increased susceptibility to infections. By pinpointing these genetic issues, healthcare providers can diagnose specific immune disorders accurately, guide treatment options, and inform family members about potential risks. The test typically involves a blood sample or cheek swab, and results help in understanding the underlying cause of immune problems and tailoring personalized care.
