Specimen Required
Defines the optimal specimen required to perform the test and the preferred volume to complete testing

Supplies: Medical Neurogenetics CSF Collection Kit (MCL T657) is required.

Container/Tube: 5 Microcentrifuge tubes from the Medical Neurogenetics CSF Collection Kit

Note: One set of tubes is required per patient.

Specimen Volume: 4.5 mL total; collected in 5 tubes as described below

CSF should be collected from the first drop into the tubes in the numbered order.

1. Fill each tube to the marked line with the required volumes.

 Tube 1: 0.5 mL

 Tube 2: 1 mL

 Tube 3: 1 mL (contains antioxidants necessary to protect the sample integrity)

 Tube 4: 1 mL

 Tube 5: 1 mL

-If sample is not contaminated with blood, the tubes should be placed on dry ice at the bedside.

-If sample is contaminated with blood, the tubes should immediately be centrifuged (prior to freezing) and the clear CSF transferred to new similarly labeled tubes, then freeze. Store samples at -80 degrees C until they can be shipped.
