DUTCH Cycle Mapping (female only)

What this laboratory test evaluates

The DUTCH Cycle Mapping™ maps the progesterone and estrogen pattern throughout the menstrual cycle. It provides the full picture of a woman’s cycle to answer important questions for patients with month-long symptoms, infertility, and PCOS.

Nine (9) targeted estrogen and progesterone measurements are taken throughout the cycle to characterize the follicular, ovulatory, and luteal phases. For some women, testing reproductive hormones (progesterone, estrogen, etc.) on a single day is sufficient. In other scenarios, the clinical picture cannot be properly captured without “mapping” out the hormonal pattern throughout their menstrual cycle.

The expected pattern of hormones shows relatively low estrogen levels early in the cycle, a surge around ovulation and modest levels in the latter third of the cycle (the luteal phase). Progesterone levels, on the other hand, stay relatively low until after ovulation. After ovulation, levels ideally increase (>10-fold) and then drop back down at the end of the cycle.
A disruption in this cycle can lead to infertility or hormonal imbalance.

Additional test information

Getting a clearer picture of a woman’s cycle can provide answers to important questions for patients with month-long symptoms, infertility, and PCOS. The DUTCH Cycle Mapping™ tracks the progesterone and estrogen patterns across the menstrual cycle – mapping 9 targeted hormone measurements throughout the cycle to characterize the follicular, ovulatory, and luteal phases. While for some women, testing reproductive hormones on a single day is sufficient – this test provides a more detailed clinical picture of the reproductive hormonal pattern that cannot be adequately captured without mapping the full cycle.

How Sunridge uses laboratory information

Sunridge considers the medical question, symptoms, history, medications, prior results, and whether the finding could change care before recommending testing. A laboratory result is not interpreted in isolation and does not establish a diagnosis by itself.

Before requesting this test

Availability, collection requirements, eligibility, and processing estimates can change. Sunridge reviews each request and, when appropriate, creates the order through Fullscript. Follow the current instructions supplied with the approved order.
