Adenine Nucleotide Testing Discontinued

Adenine Nucleotide (AdNuc) testing is being discontinued on April 1, 2024.  It is being replaced with the already available Platelet Granule Storage and Release Flow Cytometry Assay (Test Code 6417).  Please note changes to specimen receipt cut-off time.  The last day we will accept specimens for Adenine Nucleotide testing is March 29, 2024.  Click here for more information.

New Test Announcement

The Vitalant Coagulation Laboratory is pleased to announce the availability of Platelet Granule Storage and Release Testing by flow cytometry beginning Monday, March 4, 2024.  Click here for more information on this test.

Move Information

In November 2023, the Vitalant Coagulation Laboratory relocated from our location on the Boulevard of the Allies (in the Oakland area of Pittsburgh), to join other Vitalant laboratories in the Greentree area of Pittsburgh. Since we are sharing common specimen receiving areas, we’d like to ask that you label your shipping containers with “VITALANT COAGULATION LAB” to help easily identify deliveries for the Coagulation Laboratory. For those of you that have already made this change, thank you!

Our address is now:

Vitalant Coagulation Laboratory

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.
