The DNA test for Warfarin Sensitivity involves a few simple steps:
Step 1. Order the DNA Test Kit
The kit can be ordered online, by fax or mail, or by phone. Once you place the order, the testing kit will be shipped directly to you.
Step 2. Collect a DNA Sample Using the Swabs Included in the Kit
The kit contains swabs called “buccal swabs”. DNA is collected quickly and easily by rubbing the swabs inside your mouth against the cheek for 30 seconds. Once the DNA is collected, the swabs are placed into the specimen container provided in the kit and returned to the laboratory for testing using the return package included in the testing kit.
Step 3. Check Test Status and Download Results Report
Once your samples arrive at the laboratory, testing begins immediately and results are available in 1 to 2 weeks.
Step 4. Determine warfarin dose using the WarfarinDosing.org website
Patient information along with the results of this genetic analysis are entered into the algorithm and a safe and effective warfarin dose will be determined.
