Biopsies should be collected in the luteal phase of a natural cycle 7-10 days after ovulation is detected. In Mock cycles, biopsies should be collected 5-10 days after the start of progesterone.

The sample is then sent to either our South Carolina, Bellingham Washington, or New Jersey laboratories. Results are available 7-10 days after arrival in our testing facility. Cicero Diagnostics provides collection kits at no-charge to our customers.

In the event a sample is collected without one of our kits available, please place the endometrial biopsy in a vial containing 10% formalin and contact us to arrange for shipment.​ A test request form is included with every collection kit. For additional Test Request Forms, Please call Customer Service at 800-795-5385.
