Along with body temperature, blood pressure, heart rate, and respiratory rate, the menstrual cycle is thought of as another vital sign, actually the fifth vital sign in women's health. Issues in this cycle can point to hormonal disruptions, diseases, or infections and impact other health areas. The menstrual cycle can be complex due to the various hormones involved, and the fluctuations can make it challenging to track those hormones if health complications arise.
Fortunately, the Menstrual Cycle Mapping from ZRT Laboratory evaluates the varying hormone fluctuations throughout the entire month. This test provides an in-depth understanding of the different hormone levels within all the menstrual cycle phases, enabling practitioners to detect any abnormal patterns that may be linked to hormonal-related problems. Utilizing this test can empower women struggling with any associated health issues and provide guidance on how to support a healthy menstrual cycle.

What Does a Healthy Menstrual Cycle Look Like?
A healthy menstrual cycle can vary for each person and can range from a 21-day cycle to 35 days. It's important to note that some women have regular cycles with consistent lengths, and others may experience variations. These variations are considered normal as long as they fall within the range of what's typical for each individual. With that stated, let's look closer at the menstrual cycle and what it should look like.
The cycle consists of four different phases: menstruation, follicular phase, ovulation, and the luteal phase, with the cycle count starting from the first day of one period to the first day of the next. Various cyclical hormonal fluctuations regulate all of these phases. The menstruation phase typically lasts 3-7 days, and the uterine lining will shed during this phase due to a decline in progesterone and estrogen levels.
The follicular phase will start with your period and usually lasts 10-16 days. During the follicular phase, follicles mature in the ovaries, and you should see rising estrogen levels which sends feedback to the pituitary to produce a surge in luteinizing hormone (LH), triggering ovulation.
Ovulation occurs around day 14 within a 28-day cycle and can vary depending on the length of the cycle. Rising estrogen levels and the release of a mature egg for potential conception trigger ovulation.
The following phase after ovulation is the luteal phase which lasts about 14 days. LH production is suppressed during the luteal phase, and the corpus luteum will produce progesterone to support pregnancy if fertilization occurs. Otherwise, progesterone levels will drop and lead to the next period.
What is The Menstrual Cycle Mapping Test?
Understanding the menstrual cycle when issues occur can be challenging due to the various hormone fluctuations and the timeframes of those fluctuations. The menstrual cycle mapping test provides a month-long hormone assessment to help identify ovulation and hormone levels during all the menstrual cycle phases. Abnormal patterns may indicate hormone deficiencies in some women, while others may experience symptoms due to regular cycle changes. Keeping a symptom diary during the collection month will add valuable insight to the assessment.
When a single-day hormone test during the luteal phase is insufficient for diagnosis, a month-long assessment offers a comprehensive view of hormone levels throughout the menstrual cycle. Hormonal imbalances can underlie various chronic health issues, including menstrual-related conditions like PMS, PMDD, and infertility. Hormonal imbalances can influence symptoms like migraines, mood swings, and heavy or painful periods. This detailed information from the results of this test allows for more precise treatment plans to address any imbalances. It's important to note that this test is not suitable for menopausal women, those using hormones, or those who are on birth control.
What Does The Menstrual Cycle Mapping Test Measure?
The menstrual cycle mapping test measures hormones like estradiol, progesterone, and LH, as testing these levels is key to assessing hormone dysregulation in women experiencing issues like infertility or menstrual disturbances. This test utilizes frequent sample collections throughout the cycle to capture various hormonal peaks during the phases to show any abnormalities.
To avoid multiple urine collections, a daily urine sample is used for testing all three hormone levels throughout these phases, giving more accurate results. While estradiol and progesterone levels can be determined in saliva or blood, LH can only be tested in blood or urine. The ZRT test report provides results for E1G, PDG, PDG/E1G ratio, LH, and creatinine for each sample collected, and it includes graphs of hormone levels throughout the cycle. This report graphs and compares the hormones' variations to normal ranges, allowing practitioners to assess any shifts in typical hormonal patterns easily.
When to Consider The Menstrual Cycle Mapping Test
Menstrual cycle testing is valuable for cycling women who want to understand their hormone levels throughout the month, especially for investigating menstrual symptoms, PMS/PMDD, or fertility concerns.
Hormonal imbalances can underlie various chronic health issues, including conditions like PMS, PMDD, and infertility. Abnormal hormone levels can lead to migraines, mood swings, heavy bleeding, or painful periods.
Menstrual cycle mapping helps assess conditions like Luteal Phase Defect, which can cause infertility due to weak ovulation and lower progesterone levels. Anovulation, characterized by elevated LH levels and low estrogen and progesterone, can also be identified. Testing aids in diagnosing hormone-related symptoms like PMS by highlighting estrogen or progesterone imbalances during specific cycle phases.
This testing is also beneficial for women with amenorrhea or anovulatory cycles to assess LH surges for ovulation and determine the true luteal phase. It reveals delays in ovulation, corpus luteum issues, and deficiencies in estrogen or progesterone levels at any cycle point.
Practitioners use the results of these tests to help them determine the root cause of symptoms or health issues related to menstrual cycle disturbances allowing them to create individualized treatments based on those results.
How To Use The Menstrual Cycle Mapping Test in Clinic
You may be wondering how to use this test in a clinical setting. As previously mentioned, this test is completed utilizing frequent sample collections during the cycle to ensure that hormone peaks are captured, allowing for mapping the cycle and assessing any abnormalities.
This test is beneficial because it is collected as a dried urine sample to avoid using a phlebotomist for repeat blood samples. The test only requires a first-morning sample every other day. The dried urine samples remain stable for months at room temperature, allowing patients to store them at home conveniently. Additionally, urine testing assesses LH, estrogen, and progesterone, unlike saliva testing, which cannot determine LH levels. The results are accurately expressed per mg creatinine, considering the patient's hydration status, even when urine is concentrated or dilute.
To start menstrual cycle mapping, instruct your patients to collect samples from day 7 of the menstrual cycle and continue on alternate days until the next period begins. The patient will receive a kit with 15 urine collection cards, but most people will only need 11 or 12 cards, while those with longer cycles may use all 15 cards.
Retesting should be completed every 3-6 months to allow for treatments to take effect and can be used to monitor the effectiveness of treatment and if any adjustments need to be made. You should continue retesting if symptoms still persist or worsen, along with other evaluations to assess any other factors that can be contributing to the symptoms.

Summary
The menstrual cycle plays a fundamental role in women's health and is a complex process that involves many interactions of hormones and body systems. Understanding its different phases can assist healthcare practitioners in determining the best treatment approaches that are personalized to their patient’s specific needs. Utilizing comprehensive tests such as the ZRT Menstrual Mapping Test can effectively identify hormonal imbalances and cycle disruptions contributing to conditions such as PMS or infertility. This test can also help improve a woman’s overall health status by optimizing her fifth vital sign.
