Fertility Testing

If you don’t have the option of working with a knowledgeable doctor to order tests and help you understand the results, a good alternative is to order tests directly yourself, from one of the companies below.   The highest priority tests are:

  • Thyroid hormones and antibodies
  • Vitamin D
  • DHEA-S
  • AMH

Self- Testing Options: United States 

There are two main ways to self-order lab tests in the U.S. — the first is to place the order with an online service that gives you a requisition form to take to a local blood draw facility (such as Quest or Labcorp).  Companies that offer this type of testing include Life Extension and Ulta Lab Tests.

The second is home-based testing services, such as Everlywell, which can be a little more expensive, but often more convenient because you send in a finger-prick blood sample you collect at home.
