Special Info
Aseptically collect CSF from a lumbar puncture into sterile tubes. Send second tube to the Microbiology laboratory. Include specimen description (eg, LP, shunt) on requisition. Do not refrigerate specimens. CSF Gram stains are performed STAT (within 1 h of receipt in laboratory). If culture is positive, identification will be performed at an additional charge for clinically significant organisms. Identification CPT codes that may apply include: 87077, 87106, 87107, 87153, 87158. Antimicrobial susceptibilities are performed when indicated, and the following CPT codes may apply: 87181, 87184, 87185, 87186.
Clinical Info
If anaerobic infection is suspected, also order an anaerobic culture (ANACUL) in addition to the aerobic culture (CSFCUL). An order for CSFCUL on a shunt specimen includes a broth culture incubated for 14 days to optimize recovery of Cutibacterium (formerly Propionibacterium) acnes.
