FLT3 ITD and TKD Mutation Assay

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.

Submit only 1 of the following specimens:


Note: 1. If also ordering a Mayo test, send separate specimens

         2. Clinical reason for referral (AML or CML) is required

         3. Specimen source is required.

         4. Date of collection is required



Draw blood in a lavender-top (EDTA), yellow-top (ACD), or green-top (sodium heparin) tube(s). Send 5 mL EDTA, ACD, or heparinized whole blood refrigerate.


Bone Marrow

Collect bone marrow in a lavender-top (EDTA), yellow-top (ACD), or green-top (sodium heparin) tube(s). Send 3 mL EDTA, ACD, or heparinized bone marrow refrigerate.



1 ug previously isolated DNA shipped refrigerate.

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.

1 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected











Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
