By Dr. Sherry LaBeck, ZRT Laboratory  In 2008 ZRT Laboratory introduced the Fertility Profile to assist women in identifying possible hormonal causes of infertility.

ZRT Laboratory specializes in dried sample types because of their superior stability, ease of collection, simple shipment and reduced storage space. Dried urine and blood spot collection is popular with researchers and remote clients, as these sample types open the door for testing in locations that lack refrigeration and equipment necessary for liquid sample collection. In order to offer...
