Specimen Type Describes the specimen type needed for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.


       1.  Baylor collection kit (MML Supply T612) required.

Each collection kit contains 5 microcentrifuge tubes in a cardboard holder. Tube #3 contains antioxidants necessary to protect the same integrity. One set of tubes is required per patient.

  1. Baylor request form and collection protocol.
  2. Collection date
  3. Date of birth
  4. Current medications and relevant history



1)      CSF should be collected from the first drop into the tubes in the numbered order. Fill each tube to the marked line with the required volumes.

Tube 1:  0.5 mL

Tube 2:  0.5 mL

Tube 3:  1.0 mL (contains antioxidants necessary to protect

                                 the sample integrity)

Tube 4:  1.0 mL

Tube 5:  0.5 mL

- If samples not blood contaminated should be placed on dry ice at bedside

- If samples 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 Baylor Neuropharmacology request form. Include test required, sample date, date of birth, current medications and relevant history.

3)       Label tubes with patient name and ID number, leaving the tube number viewable.

4)       Place samples inside a specimen transport bag and the Baylor request forms inside the pouch of the transport bag.

      5)    Ship samples frozen on dry ice.
