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:
- Positive ACE blood test
- Exclusion of other conditions that cause enlargement of lymph nodes, raised blood calcium levels and increased urinary calcium excretion, and cardiomyopathy.
- Non-caseating granuloma on microscopic diagnosis.
Pulmonary hypertension and vasculitis is often present as well.
