Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Cerebrospinal fluid (CSF)
0.5 mL (Note: This volume does not allow for repeat testing.)
Clean sterile tube
A CSF specimen is obtained by spinal tap and should be collected in sterile tubes and submitted to the laboratory as soon as possible. Ordinarily, three samples are collected in sterile tubes, labeled sequentially as N° 1 (chemistry and immunology studies), N° 2 (microbiological examination), and N° 3 (cell count and differential). Tubes must be labeled with the patient's full name, date, time of collection, and with the number indicating the sequence in which the tubes were obtained.
Maintain specimen at room temperature.
CSF chloride may be decreased in tuberculous and other types of meningitis.
