FAQs
Card image cap

Q. My APCr (Activated Protein C Resistance) result has a comment “Suggest DNA Test.” What test should I order?
A. You should order the Factor V Leiden Mutation.

Q. How should I interpret the molecular test result as related to hypercoagulability?
A. A positive (heterozygous or homozygous) Factor V Leiden Mutation result increases the likelihood of hypercoagulability.

Q. How long will it take to get my results?
A. The turnaround time for test results depends on the frequency with which testing is performed as well as the method for result delivery to the client/physician. Please check the test menu for availability.

Q. Do I need to do anything to prepare for this blood test? E.g., fasting, etc.
A. No, there is no special preparation for any of our blood tests. However it should be noted that if you're taking any aspirin or aspirin-related medications, heparin or coumadin/warfarin, these will affect the interpretation of your results.
