Dried Urine Cycle Mapping: How to Collect Samples

Menstrual cycle mapping uses repeated dried-urine samples over a month. The U-328 Menstrual Cycle Mapping test page says to collect urine on a filter card every other morning. The panel-specific dried-urine collection instructions explain the exact start day, card preparation and handling. Read them before you begin and use them as the authority for your kit.

What does the test measure?

The product page lists four measurements: PDG, a progesterone metabolite; E1G, an estrogen metabolite; luteinizing hormone (LH); and creatinine. Repeated samples can show how these markers vary during the month. Results are not, on their own, a diagnosis or explanation for symptoms.

Plan the month-long schedule

Before collecting, check the PDF for when to start, how to follow the every-other-morning schedule and how to label each card. Mark the collection dates on a calendar and set out the supplied cards and paperwork. The exact start day is important for following your kit’s schedule, so don’t substitute timing from another test or infer the start day.

Collect and dry each urine card

At each scheduled collection, use the filter card and method shown in the PDF. Complete the card details as instructed, then let the sample dry fully before storing it. Keep the cards organised throughout the month. The product page says the dried cards can be kept at room temperature and do not need refrigeration or freezing.

When the month’s collections are complete, return the dried cards and paperwork using the kit’s packaging and shipping instructions. The product page lists results within 3–5 working days after the laboratory receives the samples.

Check whether the test is suitable

The product page says this test is not designed for people using birth control or hormone supplements, or for post-menopausal women. If any of these apply to you, ask a qualified healthcare professional or the laboratory about suitability before ordering.
