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

Medical Neurogenetics collection kit (MCL T657) required.

 

NOTE:

One set of tubes is required per patient.

Total CSF volume required is 4.5 milliliters

Each collection kit contains 5 micro centrifuge tubes.

Tube #3 contains antioxidants necessary to perform this test.

 

COLLECTION PROTOCOL:

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: 1.0 mL

       Tube 3: 1.0 mL (contains antioxidants necessary to protect the sample integrity)

       Tube 4: 1.0 mL

       Tube 5: 1.0 mL

-       If sample's not blood contaminated, the tubes should be placed on dry ice at bedside

-       If sample's are blood contaminated, the tubes should immediately be centrifuged (prior to freezing) and the clear CSF transferred to new similarly labeled tubes, then frozen

-       Store samples at -80 until they can be shipped

2)     Complete Medical Neurogenetics, LLC request form.
