Cerebro-spinal fluid (Microscopy and Culture)
Investigation of suspected bacterial meningitis or subarachnoid bleed.
Suspected bacterial meningitis should be confirmed by lumbar puncture. A high white cell count along with positive gram stain would support diagnosis.
For suspected SAH send sample 1 & 3 to compare counts.
Containers must be clearly labelled. Where possible send separate tubes for each test requested.
| Tube | Sterile universal |
|---|---|
| ID | 3619 |
| Availability | Processing 24/7Positive results released to server 24/7Please contact laboratory prior to sending. |
| Additional Information | Pre antibiotic CSF will give better culture yields but this does not imply to withhold antibiotic therapy. |
| Turn Around | Cell Count - within 1 hour if laboratory is notified prior to arrivalStandard culture -5 daysNeuro ward culture -7 days |
| Send to | LGI Microbiology Department |
| Collection Con | Observe aseptic sampling technique for performing lumbar puncture and decanting sample into sterile universal containers. Transport the sample to the laboratory as quickly as possible. Note: The recovery of anaerobes is compromised if the transport time exceeds 3 hours. |
| Sample REQ | Min vol 0.5ml. If further tests required contact |
