Immune Disorders :: Wiskott Aldrich syndrome Diagnosis
To diagnose Wiskott Aldrich syndrome – WAS, a doctor will do a blood test. In boys with WAS, the blood will show low numbers of platelets. The platelets that appear will be smaller than normal. In boys older than 2 years, tests of blood and skin cells will show problems with immune system functions. To be certain of the diagnosis, a doctor can also do a genetic test to look for a mutation of the gene that is linked to WAS.
