Medical Genetics An immunodeficiency disorder should be considered in anyone with infections that are unusually frequent severe, and resistant without a symptom-free interval; from an unusual organism; or with unexpected or severe complications

Medical Genetics Since immunodeficiency disorders are relatively uncommon other disorders leading to recurrent nfection should be considered first If these disorders can be excluded a defect in host defense should be suspected
