Collection & Request Instructions

CSF must be delivered to laboratory immediately; cellular degeneration occurs within 30 minutes.

The sample with the least amount of blood is prefered for Cytology.

Collect CSF into three separate, sterile, screw-capped tubes provided (labelled 1,2 & 3)

Tube 1 is for Biochemistry (for Protein and Glucose) 0.5ml (10 drops) required

Tube 2 for Cytology 1.0ml (20 drops)  and/or Flow Cytometry (6ml)

For Flow Cytometry a minimum of 6ml is required  in Tube 2

For Flow Cytometry and Cytology a minimum of 7ml is required in Tube 2    

Tube 3 for Microbiology upto 10ml (Full tube)

Xanthochromia investigation requires a 4th tube containing 1ml of CSF .

External Transport Instructions

All out of hours specimens from Anglss and Maroondah should be sent to Box Hill ASAP for processing.

After hours cytology CSF can be prepared by microbiology staff. In the event microbiology staff are not in attendance and will not be called in, please call the Anatomical Pathology Scientist on call.

After hours cytology CSF can be prepared by microbiology staff. In the event microbiology staff are not in attendance please store in the AP fridge.

Method

CSF sample processing:

If Cytology/Flow Cytometry requested  : Tube 1-Biochemistry, Tube 2- Cytology/Flow Cytometry, Tube 3-Microbiology

If Cytology/Flow Cytometry not requested: Tube 1 and 3-Microbiology, Tube 2-Biochemistry

Any confusion between the terms cell count and cytology could be cleared up when the cell count is rung through to the requesting doctor by the scientist. At this point it could be determined whether cytology is a genuine request or not (all to be documented in F8 notes). The CSF can then be forwarded expediently to BHH for cytospin if required.
