Kveim test is used for diagnosis of?: (A) Sarcoidosis, (B) Sicca syndrome, (C) Scleroderma, (D) C.R.E.S.T syndrome
Answer is A. The Kveim-Siltzbach test is a skin test used to detect sarcoidosis, where part of a spleen from a patient with known sarcoidosis is injected into the skin of a patient suspected to have the disease. If non caseating granulomas are found (4-6 weeks later), the test is positive.
