This test is not limited to the CPT codes listed. Others may be added as more testing is necessary and depending on the pathogens isolated (example: MIC's and ID codes)
Description
Includes Quantitative Bacterial Culture for the major CF pathogens. Specimen is cultured for Aerobic bacteria only. Samples that do not meet the minimum required volume (0.3 grams) are processed as Qualitative cultures. This culture is meant for Cystic Fibrosis patients only. For non-CF patients, see Sputum Culture.
Note: Routine Sensitivity testing is not performed on CF Respiratory culture isolates. If provider would like to request full sensitivity testing, this can be requested when culture order is placed in Pathnet (Order comment field). Alternatively, provider can place "Add-On" order after isolate is identified in culture. PBP (penicillin binding protein) latex testing will be performed on all Staph aureus isolates in place of full sensitivity to determine if the isolate is MRSA or MSSA.
