Ordering the Fertility Profile | ZRT Labs
The Fertility Profile from ZRT Labs measures a range of hormones and markers that play a direct role in reproductive function, menstrual cycles, and hormone balance. This test can help pinpoint specific hormone imbalances that may be linked to symptoms like irregular periods, low energy, or trouble conceiving. Interestingly, this panel includes both saliva and bloodspot samples, which allows for a more complete view of hormone patterns throughout the day and month.
Ordering the Fertility Profile | ZRT Labs provides several specific benefits:
- Tracks hormone fluctuations that may affect ovulation and menstrual cycles.
- Assesses thyroid function, which can impact fertility and energy levels.
- Measures stress hormone (cortisol) patterns that may disrupt reproductive hormones.
- Identifies estrogen and progesterone imbalances that can cause PMS, hot flashes, or mood changes.
- Evaluates androgens and binding proteins that may be linked to hair loss, acne, or low libido.
Who Should Consider Hormone and Reproductive Marker Testing
People who have been trying to conceive for several months without success, or who experience symptoms like irregular cycles, unexplained fatigue, or mood swings, may benefit from this test. For example, someone who has noticed their periods becoming less predictable and is also experiencing night sweats and trouble sleeping may find answers through this panel.
Ordering this test may also be helpful in these situations:
- Experiencing symptoms of menopause, such as hot flashes or sleep disturbances.
- Dealing with persistent acne or hair thinning that has not improved with standard treatments.
- Having a history of polycystic ovary syndrome (PCOS) and wanting to monitor hormone changes.
- Noticing sudden weight gain or difficulty losing weight despite healthy habits.
- Feeling unusually anxious or stressed, especially if it seems to affect menstrual cycles or libido.
Testing these markers can help identify specific hormone patterns that may be causing symptoms like missed periods, low energy, or changes in mood. Delaying this test could mean missing the chance to address hormone imbalances early, which may make it harder to manage symptoms or plan for pregnancy.
Preparing for Comprehensive Hormone and Fertility Testing
Fasting is not required for this test, so you can eat and drink as usual before collecting your samples. Make sure to carefully follow any instructions your doctor or healthcare provider gives you about when and how to collect your saliva and bloodspot samples for the most useful results.
Labs Included When Ordering Your Fertility Profile | ZRT Labs
| Test Name | Reference Range | What the Marker Means | Low and High Levels of the Marker |
|---|---|---|---|
| Cortisol x 4 (Saliva) | Morning: 3.7-9.5 ng/mL Afternoon: 1.2-3.0 ng/mL Evening: 0.6-1.9 ng/mL Night: 0.4-1.0 ng/mL |
Cortisol is a hormone made by the adrenal glands that helps control stress, energy, and sleep patterns. Testing at four times shows how your levels change throughout the day. | High levels mean your body may be under stress or your adrenal glands are overactive.
Low levels mean your adrenal glands may not be making enough cortisol, which can cause fatigue and low energy. |
| Estradiol (E2) | Follicular: 1.3-3.3 pg/mL Ovulation: 3.3-7.1 pg/mL Luteal: 2.5-7.1 pg/mL Postmenopausal: 0.3-1.0 pg/mL |
Estradiol is the main form of estrogen in the body and is important for menstrual cycles, bone strength, and mood. It changes throughout the cycle. | High levels mean you may have estrogen dominance, which can cause heavy periods or mood swings.
Low levels mean you may have missed ovulation or be in menopause, which can cause hot flashes or bone loss. |
| Progesterone | Follicular: 12-100 pg/mL Luteal: 75-270 pg/mL Postmenopausal: 5-50 pg/mL |
Progesterone is a hormone that helps prepare the uterus for pregnancy and supports regular cycles. It rises after ovulation. | High levels mean you may be in the luteal phase or pregnant.
Low levels mean you may not be ovulating, which can cause irregular periods or trouble getting pregnant. |
| Testosterone | Women: 16-55 pg/mL Men: 44-148 pg/mL |
Testosterone is a hormone that supports muscle strength, mood, and sex drive in both men and women. It also affects hair growth and energy. | High levels mean you may have symptoms like acne, hair loss, or PCOS.
Low levels mean you may feel tired, have low libido, or lose muscle mass. |
| Sex Hormone Binding Globulin | 18-114 nmol/L | Sex Hormone Binding Globulin (SHBG) is a protein that carries hormones like testosterone and estrogen in the blood. It controls how much hormone is available for the body to use. | High levels mean less free hormone is available, which can lower sex drive or energy.
Low levels mean more free hormone is available, which can cause symptoms like acne or hair growth. |
| DHEAS | Women: 40-290 µg/dL Men: 70-495 µg/dL |
DHEAS is a hormone made by the adrenal glands that helps make other hormones like estrogen and testosterone. It supports energy and mood. | High levels mean your adrenal glands may be overactive, which can cause acne or hair growth.
Low levels mean your adrenal glands may be underactive, which can cause fatigue or low mood. |
| Thyroid Stimulating Hormone | 0.5-4.5 mIU/L | Thyroid Stimulating Hormone (TSH) tells the thyroid gland to make hormones that control metabolism, energy, and body temperature. | High levels mean your thyroid may be underactive, which can cause tiredness or weight gain.
Low levels mean your thyroid may be overactive, which can cause anxiety or weight loss. |
| T3, Free | 2.3-4.2 pg/mL | Free T3 is the active form of thyroid hormone that helps control how your body uses energy. It is important for mood, weight, and temperature. | High levels mean your thyroid may be overactive, which can cause sweating or fast heartbeat.
Low levels mean your thyroid may be underactive, which can cause tiredness or feeling cold. |
| T4, Free | 0.8-1.8 ng/dL | Free T4 is another thyroid hormone that helps control metabolism and energy. It works with T3 to keep your body running smoothly. | High levels mean your thyroid may be overactive, which can cause nervousness or weight loss.
Low levels mean your thyroid may be underactive, which can cause tiredness or dry skin. |
| Thyroid Peroxidase | <9 IU/mL | Thyroid Peroxidase is an enzyme that helps make thyroid hormones. High levels of antibodies can mean the immune system is attacking the thyroid. | High levels mean you may have thyroid autoimmunity, which can cause thyroid problems.
Low levels mean your immune system is not attacking the thyroid. |
| Follicle Stimulating Hormone | Follicular: 3.5-12.5 mIU/mL Ovulation: 4.7-21.5 mIU/mL Luteal: 1.7-7.7 mIU/mL Postmenopausal: 25.8-134.8 mIU/mL |
Follicle Stimulating Hormone (FSH) helps control the menstrual cycle and egg growth in women, and sperm production in men. | High levels mean your ovaries may not be working well, which can cause trouble getting pregnant.
Low levels mean your brain may not be sending enough signals to the ovaries or testes. |
| Luteinizing Hormone | Follicular: 2.4-12.6 mIU/mL Ovulation: 14.0-95.6 mIU/mL Luteal: 1.0-11.4 mIU/mL Postmenopausal: 7.7-58.5 mIU/mL |
Luteinizing Hormone (LH) triggers ovulation and helps control the menstrual cycle. It also supports hormone production in men and women. | High levels mean you may be ovulating or have PCOS.
