As we prepare for Thanksgiving, we wanted to take a moment to tell you how grateful we are for your continued support. Together, we’ve uncovered meaningful health insights for hundreds of thousands of families.

In observance of the holiday, Counsyl will be closed on Thursday & Friday, November 26 & 27th 2015.

We will be accepting samples for processing, as usual, on Saturday, November 28th and again on Monday, November 30th.

As a reminder, we recommend that Counsyl Informed Pregnancy Screen samples be shipped within 24 hours of collection with our FedEx Priority Overnight remailer. These samples must be received within five days of collection.

Please contact our Support Team prior to the holiday if you have any questions. Counsyl will resume normal support operations at 6AM PST on Monday, November 30th.

Thank you for choosing Counsyl. We strive to provide the highest standard of service for you and your patients.
