Thank you for your interest

RepeatDx® does not provide telomere testing services direct-to-the-consumer (known as “DTC” testing) but only through healthcare professionals.

To Order A Telomere Test

To order, please select the order form for your region, fill it in online, print and sign it.

Please note: It is very important to collect and ship the blood specimen in the morning and only from Monday to Wednesday.
To ensure samples reach us in a timely manner we recommend using FedEx International Priority. As of March 26, 2020, UPS has suspended their Service Guarantee. 

Please contact us to inform the team of the date shipped and tracking number.

There are important considerations when conducting testing as results could indicate a heritable condition that may have implications for families as well as the individual being tested. Genetic counseling can be a helpful way for individuals and their families to discuss and prepare for testing and test results. For more information read this guest blog from a genetic counselor examining some of the implications that come with telomere testing.


All sample preparation and shipping instructions are included as part of the sample requisition documents.

Turn Around Time

Please allow up to 15 business days for the processing and testing of your sample. An expedited service is also available.

When RepeatDx cannot perform a telomere test due to temporary instrumentation or reagent difficulties, RepeatDx does not send the specimen to another laboratory for testing. When possible, we will repeat the measurement on reserve specimens that were frozen on arrival. These specimens will be processed ASAP.

When unexpected delays occur, you will be notified.
