Laboratory evaluation Peripheral eosinophilia > 10% • Chronic eosinophilic pneumonia • Sarcoidosis Abnormal renal function - Pulmonary-renal syndromes Precipitating antibodies to specific antigens -HP
ANA testing It is recommended to get following tests done for all ILD patients at the onset – • ANA testing (by indirect immunofluorescence) • Rheumatoid factor (RF) • Anti CCP testing Additional serologic testing should be advised in patients with a high pre-test probability for connective tissue disease (CTD)-ILD
RF, ANA, anti-CCP → if positive → Get full collagen panel done • RF/Anti-CCP – Rheumatoid arthritis • ANA/Anti-dsDNA - SLE • Anti Jo1 – Polymyositis / Dermatomyositis • Anti U1RNP – Mixed connective tissue disease • Anti Scl-70 - Scleroderma • Anti SSA, SSB – Sjogren’s syndrome • Angiotensin converting enzyme - Sarcoidosis • ANCA – Granulomatosis with polyangitis
