Hemophilia B, Factor IX Gene Mutation Screening

Specimen Type Describes the specimen type needed for testing

Whole blood

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.

Container/Tube: 

Preferred: Yellow top (ACD solution B)

Acceptable: EDTA or sodium citrate

Specimen Volume: 6 mL

Collection Instructions:

1. Invert several times to mix blood. 

2. Send specimen in original tube.

Forms:

1. Hemophilia B Patient Information Sheet (Supply T518) in Special Instructions

2. New York Clients-Informed consent is required. Please document on the request form or electronic order that a copy is on file. An Informed Consent for Genetic Testing (Supply T576) is available in Special Instructions.

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.
