Description: The Rhythm™ hormone test is a comprehensive assessment of estradiol, progesterone, and testosterone spanning a full 28 days. Hormone imbalances revealed in this hormone test profile can help illuminate root causes of disorders such as premenstrual syndrome (PMS), infertility, and menstrual irregularities. This hormonal test analyzes 11 saliva samples of a 28–day period.

Saliva hormone testing provides a thorough analysis of estradiol and progesterone over a full 28 day cycle. Testosterone is measured once from the 28th day specimen. By utilizing 11 saliva samples for analysis, the relationship and balance of these essential hormones are analyzed more precisely through time. The levels of estradiol and progesterone, as well as the ratio between the two, are clearly graphed for easy reference and patient education.

Unlike serum measurements that typically reflect both bound and unbound fractions of hormones, salivary samples represent only the free (unbound) bioavailable fraction of hormone. Factors that affect binding globulin such as obesity and thyroid function do not influence test results with false high or low test levels.

The Rhythm profile is a hormonal test indicated for both premenopausal and perimenopausal women not currently supplementing with hormones. An analysis of estrogen, progesterone and testosterone can reveal ovulatory function and trends in hormone production. Hormonal imbalances such as unopposed estrogen, high follicular progesterone, anovulation and luteal phase defects are easily identified. This hormone test is especially useful in treatment of patients with chronic gynecologic disorders.
