Collect

Specimen Type	Type of Container	Volume of Specimen	Status
CSF	CSF tube 2	1.5 mL	Preferred

Outpatient Specimen Preparation

CSF: Do not centrifuge

Unacceptable Conditions

Centrifuged specimen, Diluted specimen, CSF not collected via lumbar puncture such as Shunt or ventricular fluid

Stability

CSF: Room temperature 24 hour(s)
CSF: Refrigerated 7 day(s)
CSF: Frozen indefinite day(s)

Remarks

Testing is performed on lumbar puncture collections only.
CSF collected via shunt or other indwelling device will be rejected.
A CSF culture (Bacterial) is required with each order, if not already obtained.
Samples with insufficient volume for both the Meningitis/Encephalitis Infection Array and CSF culture will have the Meningitis/Encephalitis Infection Array canceled and the CSF culture will be performed.
Outside institutions should submit CSF protein, glucose, cell count, differential, and gram stain results with requests for MEID testing. If such testing results do not accompany order request, ordering location will be contacted with request for associated testing results.
