Neurotransmitter Metabolites/Amines

Specimen Type Describes the specimen type needed for testing

CSF

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.

 Medical Neurogenetics collection kit (MML Supply T657) required.

Each collection kit contains 5 microcentrifuge tubes.

 

COLLECTION PROTOCOL:

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 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. Include test required, sample date and date of birth.

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

4)     Place samples inside a specimen transport bag and the Medical Neurogenetics, LLC request form inside the pouch of the transport bag.

5)     Ship samples frozen on dry ice.

 

 

 

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
