ZRT offers simple, cost-effective testing to identify treatable hormone imbalances that affect fertility. Early detection can help your patients address these issues and identify the need for more specialized care. The ZRT Fertility Profile is geared to women who have irregular cycles or fertility issues, who have been trying to get pregnant without success, or who would like to be proactive in their preconception planning by getting a baseline screening.
Many women become pregnant easily, but for others this may require some assistance. ZRT’s Fertility Profile can help if your patients:
Too often women struggle wondering why they are unable to conceive while feeling as if the clock is ticking. Testing can help them find out if more assistance is needed from a specialist or give them peace of mind when conceiving is taking longer than they had hoped.
Hormones are tested in blood collected by fingerstick and dried on filter paper, and in saliva. ZRT Laboratory was one of the first labs to develop and commercialize this convenient and accurate testing. In a study published in Fertility and Sterility, dried blood spot testing performed by ZRT Laboratory was found to be as accurate as traditional serum testing for the fertility markers LH, FSH, Pg, and E2. Patients can collect their samples conveniently and at the appropriate cycle times with minimal disruption to their lives and busy work schedules. Sampling is done on days 3 and 21 of the menstrual cycle. The day 3 sample is optimal for assessment of ovarian reserves with the FSH and LH tests, while the other hormones are measured mid-luteally (day 21 commonly), when the level of hormones should be optimal for a successful pregnancy.
ZRT’s comprehensive test report is easy to interpret and includes not only the hormone test numbers in an easy to read format, but also your patient’s self-reported symptoms, medications, and hormones used, along with comprehensive individualized comments explaining how their hormonal imbalances could be causing infertility.
