Overview
Laboratory Findings
- There are no specific laboratory findings associated with cryptogenic organizing pneumonia.
- If there is the history of cryptogenic organizing pneumonia and patients present with a cough, fever, and dyspnea then following laboratory test is to be done:[1]
- Complete blood count with differentials- leukocytosis is found in most of the patients.[2]
- Blood urea nitrogen
- Creatinine
- Urinalysis
- ESR
- C-reactive protein
- To find the etiology of cryptogenic organizing pneumonia following tests are done:
- Test for antibodies to rule out connective tissue disorder.
- Antinuclear antibody
- Rheumatoid factor
- Anti-topoisomerase [anti-Scl70]
- Anti-centromere antibody
- Anti-double-stranded DNA
- Anti-JO1
- To rule out pneumonia, following tests are done:[3]
- Blood cultures
- Sputum gram stain
- Sputum enzyme immunoassay (EIA)
- Immunofluorescence
- Polymerase chain reaction (PCR) for respiratory viruses
- Urinary studies for pneumococcal and Legionella antigen
- HIV testing
- Test for antibodies to rule out connective tissue disorder.
