Sarcoidosis Is A Chronic Disease That Is Classified As  A systemic Infiltrative Disease.

Diagnostic Criteria for Sarcoidosis

Sarcoidosis can only be diagnosed reliably only with a microscopic examination of tissues invloved with the disease. There is no single specific X-ray, CT scan, or blood test for it. Clinically, three requirements for diagnosis are:

1. Positive ACE blood test
2. Exclusion of other conditions that cause enlargement of lymph nodes, raised blood calcium levels and increased urinary calcium excretion, and cardiomyopathy.
3. Non-caseating granuloma on microscopic diagnosis.

Pulmonary hypertension and vasculitis is often present as well.
