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.
Medical Neurogenetics collection kit (MML Supply T657) required.
Each collection kit contains 5 microcentrifuge tubes.
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 Medical Neurogenetics, LLC 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
4) Place samples inside a specimen transport bag and the Medical
Neurogenetics, LLC request form inside the pouch of the transport
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.
Specimens other than
CSF in special collection kit (MML supply T657)
Anticoagulants other than
Warm reject; Cold reject
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
