The Comprehensive Male Profile I by ZRT Laboratory is a comprehensive hormone test designed to assess various aspects of male health and hormonal balance. This test analyzes key hormones in male physiology including testosterone, estrogen, cortisol, DHEA-S, and thyroid hormones, providing valuable insights into reproductive health, metabolism, energy levels, and stress response. It also includes a PSA, or prostate specific antigen, a marker used to inform doctors of an individual’s need for further prostate cancer screening. [13.]
By evaluating hormone levels in saliva and dried blood spots, this profile offers a non-invasive and convenient way to assess male hormonal status. The results can help identify hormone imbalances associated with symptoms such as fatigue, low libido, weight gain, mood swings, and muscle loss, guiding personalized treatment strategies for improved overall health and well-being.
The Comprehensive Male Profile I by ZRT Laboratory tests several biomarkers crucial for assessing men's health:
Testosterone: Testosterone levels are vital for male reproductive health, libido, muscle mass, bone density, and overall well-being. Low testosterone levels can lead to symptoms such as low libido, fatigue, and erectile dysfunction and early aging. [10.]
Estradiol: Estradiol, a form of estrogen, plays a role in regulating libido, bone density, and cognitive function in men. [VILLACA, BRAN] Knowing their estrogen level may be important in men receiving testosterone replacement therapy, or men with a family or personal history of gynecomastia (male breast enlargement). [14.]
Cortisol: Cortisol is a stress hormone produced by the adrenal glands that plays a critical role in the body's stress response, metabolism, immune function, and energy levels. Dysregulation of cortisol levels can lead to adrenal dysfunction and contribute to symptoms such as fatigue, insomnia, and mood disturbances [McEwen]. By testing salivary levels of cortisol at 4 time points in a 24 hour period, this test maps out the individual’s diurnal cortisol rhythm and may provide insight into chronic stress, sleep disturbances, immune or digestive dysfunction, and more. [1.]
DHEA-S (Dehydroepiandrosterone Sulfate): Dehydroepiandrosterone (DHEA) is a hormone produced by the adrenal glands (and in smaller amounts in the ovaries and testes); a sulfate group is added to DHEA in the adrenal glands and the liver, forming DHEA-S. DHEA-S can be converted into other hormones, including estrogen and testosterone. It plays a role in regulating mood, energy levels, and overall hormonal balance. It can be used as a marker for adrenal function, stress response, and overall energy and resiliency levels. [2.]
Thyroid Hormones: (TSH, Free T3, Free T4, anti-TPO antibodies): Thyroid hormones, T3 and T4, are essential for regulating metabolism, energy production, and overall health and body functions. TSH, thyroid stimulating hormone, is a hormone made in the pituitary gland which stimulates thyroid hormone production and release in the thyroid gland. Abnormalities in thyroid hormone levels can lead to symptoms such as fatigue, weight changes, and mood disturbances. [GARBER] Assessing an individual’s level of anti-TPO antibodies is an important step to rule out Hashimoto’s thyroiditis, an autoimmune thyroid condition that causes eventual hypothyroidism. [9.]
Prostate-Specific Antigen (PSA): PSA levels are important for monitoring prostate health and screening for conditions such as prostate cancer and benign prostatic hyperplasia (BPH). Patients should discuss results with their healthcare provider within the context of their age, family history, demographics, and lifestyle. [13.]
These biomarkers provide insights into various aspects of men's health, including reproductive function, adrenal health, stress response, metabolism, and overall well-being.
The Comprehensive Male Profile I by ZRT Laboratory can benefit various groups of individuals, including:
Men experiencing symptoms related to hormonal imbalances: in men, testosterone levels naturally begin to decline with age, usually beginning around the mid-40’s. Fatigue, changes in libido, mood swings, weight gain, and the development of metabolic syndrome and osteoporosis may be signs of hidden hormone imbalance. [15.]
Men with high levels of chronic stress, suspected thyroid disorders or autoimmune conditions: as the profile includes both a diurnal cortisol curve and a thyroid panel including anti-thyroid peroxidase (anti-TPO) antibodies, this test sheds light on potential thyroid/adrenal imbalances which may cause troubling hormone imbalance symptoms. [8., 11., 17.]
Men undergoing hormone replacement therapy or testosterone supplementation: the Comprehensive Male Profile I by ZRT Laboratory can be used to monitor hormone levels and optimize treatment outcomes. Salivary testosterone levels are recognized as a valid testing approach to assess testosterone levels in men. [3., 6.]
Men interested in preventive healthcare and optimizing their overall well-being: hormone imbalance in men may be an underlying factor in age- and lifestyle-related conditions including metabolic syndrome, loss of muscle mass, low libido, and others. Assessing hormonal balance and metabolic health can help uncover these factors. [4., 10.]
Patients using certain medications including steroids should consult their healthcare provider regarding optimal collection timing. Avoidance of certain medications, 7-keto DHEA supplements and anti-aging facial creams for up to 3 days prior to testing may be necessary.
Patients using hormone replacement therapy should collect samples according to the schedule below, unless otherwise directed by their healthcare provider.
Samples should be shipped as soon as possible after collection to ensure accurate results.
Various guidelines exist for those using different forms of hormones or steroids, emphasizing proper timing and avoidance of certain substances before testing. People taking glucocorticoids should consult their healthcare provider before making any changes in their dosing schedule.
The general recommendations for people using hormone replacement is as follows:
If you use topical or oral hormones:
Apply/take any night dosage at least 12 hours prior to your morning collection.
Avoid applying hormones with your bare hands for at least 2 days prior to collection.
Avoid using hormones on your face, lips, and neck.
Change your sheets, pillowcases, and hand towels the night before collection.
Avoid touching any surfaces which may be contaminated with hormones prior to collection; this includes faucets, hand towels, cabinet doors, etc..
If you use hormone patches, pellets, or injectables,
Test halfway between doses.
Example: 3 days after a once-a-week patch, or 6 weeks after insertion of pellets dosed every 3 months.
If you use sublingual hormones or troches,
Talk to your healthcare provider. It is not recommended that you take this test.
If you are taking steroids (glucocorticoids, prednisone, etc.), talk to your healthcare provider about appropriate timing.
Blood spot collection involves washing hands, pricking the finger, and saturating the filter paper with blood drops.
The blood spot card should be left to air dry for at least 4 hours before packaging.
Saliva collection involves collecting samples at specific times and using provided tubes to pool saliva.
Saliva should be collected in the morning upon waking, before lunch, before dinner, and before bed.
Samples should be shipped back to the lab as soon as possible after collection, ensuring they remain dry and intact during transit.
Proper packaging and labeling are essential to facilitate the shipping process.
Results are typically available 3-5 business days after samples are received at the lab.
Healthcare providers will notify patients when results are ready and schedule follow-up appointments to discuss them
