Hemophilia B, F9 Gene Mutation Analysis, Whole Blood
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
Maternal cell contamination testing will be performed for all cord blood specimens. A maternal whole blood sample is required to perform this test.
The following algorithms are available in Special Instructions:
-Hemophilia Carrier Testing Algorithm
-Hemophilia Testing Algorithm
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.
Preferred: Lavender top (EDTA) or yellow top (ACD)
Acceptable: Sodium citrate
Specimen Volume: 6 mL
1. Invert several times to mix blood.
2. Send specimen in original tube.
1. Hemophilia B: Patient Information (T518) in Special Instructions is required. Please fax the completed form to 507-284-8286.
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 (T576) is available in Special Instructions.
3. If not ordering electronically, complete, print, and send a Coagulation Test Request Form (T753) with the specimen (http://www.mayomedicallaboratories.com/it-mmfiles/coagulation-test-request-form.pdf)
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.
