Bacterial Culture, Cystic Fibrosis, Respiratory
Use
This test is useful for detecting disease-causing aerobic bacteria in specimens from patients with cystic fibrosis. Chronic lung infection is responsible for a major portion of deaths in cystic fibrosis patients. The test isolates bacteria commonly associated with pulmonary disease in CF patients, like Pseudomonas aeruginosa, Staphylococcus aureus, and Burkholderia cepacia complex among others.
Special Instructions
If antimicrobial susceptibilities are needed, order CFRCS / Bacterial Culture, Cystic Fibrosis with Antimicrobial Susceptibilities, Varies. Specimen source is required. The specimen must arrive within 48 hours of collection.
Limitations
The test may not detect bacterial agents like mycobacteria, Legionella species, or Mycoplasma pneumoniae. Negative results do not exclude the possibility of infectious lung disease. Overgrowth of usual oropharyngeal microbiota can occur if culture of sputum is delayed. Clinicians should consider additional testing for bacterial, viral, or fungal agents if the culture is negative.
