Tests & Diagnosis
IRAK-4 deficiency can be diagnosed by very specific immune tests to determine if a person has an impaired response to most Toll-like receptor (TLR) and interleukin-1 receptor (IL-1R) agonists. Genetic testing is also available for IRAK-4 deficiency and can be used to confirm the diagnosis. The Genetic Testing Registry provides information on available genetic test for this condition. Because many laboratories do not accept direct contact from patients, we recommend that you work with your health care provider if you are interested in genetic testing.
