Method Name

HPLC/Electrochemistry/Fluorescence

Reporting Name

Pyridoxal 5-phosphate Conc., CSF

Specimen Type

CSF


Shipping Instructions


Ship samples frozen on dry ice



Specimen Required


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.

       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
