Method and collection

Enzymatic
Collection
A CSF specimen is obtained by spinal tap and should be collected in sterile tubes and submitted to the laboratory as soon as possible. A simultaneous blood glucose level should also be obtained and submitted. Ordinarily, three samples are taken in sterile tubes and 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 patient's full name, date, time of collection, and with the number indicating the sequence in which the tubes were obtained.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
