Your hormones do not operate in isolation—they function as an interconnected network, and when one system shifts, others often follow. The Advanced Hormone Function Analysis at The Longevity Center FL is a physician-guided evaluation designed to assess three key endocrine systems in context, not just in isolation. Led by Dr. Benjamin Kosubevsky, with advanced training in Osteopathic, Regenerative, and Integrative Medicine, this assessment is available to patients in West Palm Beach and across South Florida who want a more complete understanding of how their hormonal health may be influencing the way they feel and function.
A standard primary care workup may include only TSH for thyroid or total testosterone for male patients. While these markers have clinical value, peer-reviewed guidelines have noted that single-marker screening may not capture the full picture of endocrine function (Garber et al., Thyroid, 2012; Bhasin et al., Journal of Clinical Endocrinology & Metabolism, 2018). Our approach evaluates multiple markers across each system to provide a broader, more clinically useful view.
The Advanced Hormone Function Analysis is a physician-guided wellness evaluation. It is intended to inform personalized wellness and hormone optimization planning, not to independently diagnose, treat, cure, or prevent any specific disease. Hormone levels vary based on age, sex, time of day, menstrual cycle phase, and individual physiology. Interpretation of results should always occur in the context of a complete clinical evaluation. This service is not a substitute for evaluation by your primary care physician or endocrinologist.
Rather than testing hormones as isolated data points, our Advanced Hormone Function Analysis evaluates three endocrine systems that frequently interact and influence one another.
Sex hormones influence far more than reproductive function—they play roles in body composition, bone density, cardiovascular wellness, mood, cognition, and energy. Our panel may include total and free testosterone, estradiol, progesterone, DHEA-S, sex hormone-binding globulin (SHBG), follicle-stimulating hormone (FSH), and luteinizing hormone (LH). For men, longitudinal research has demonstrated that testosterone levels may decline gradually with age, though the clinical significance varies widely between individuals (Harman et al., Journal of Clinical Endocrinology & Metabolism, 2001). For women, the Endocrine Society has noted that androgen assessment can provide important clinical context in the evaluation of wellness concerns such as fatigue and changes in libido (Wierman et al., Journal of Clinical Endocrinology & Metabolism, 2014).
The thyroid gland regulates metabolism, body temperature, heart rate, and energy production. A comprehensive thyroid evaluation goes beyond TSH to include free T3, free T4, reverse T3, and thyroid antibodies (TPO and thyroglobulin). Clinical practice guidelines have emphasized that TSH alone may not adequately characterize thyroid function in all patients, particularly those with subclinical presentations or autoimmune thyroid patterns (Garber et al., Thyroid, 2012; Jonklaas et al., Thyroid, 2014). Evaluating the full thyroid cascade may provide additional context for patients experiencing fatigue, weight changes, temperature sensitivity, hair thinning, or mood fluctuations.
The adrenal glands produce cortisol, DHEA, and other hormones that help regulate the body’s response to stress, inflammation, blood sugar, and immune function. Cortisol follows a natural diurnal rhythm—typically highest in the morning and lowest at night. Disruptions in this pattern, whether from chronic stress, sleep disturbances, or other factors, may be associated with symptoms such as fatigue, difficulty concentrating, disrupted sleep, or changes in appetite. Where clinically indicated, we may assess morning cortisol, DHEA-S, and related markers to evaluate adrenal function as part of the broader hormonal picture.
Hormonal symptoms rarely trace back to a single marker. Fatigue, for example, may be associated with thyroid function, sex hormone levels, adrenal output, or any combination. Weight gain that resists conventional approaches may involve insulin sensitivity, thyroid conversion, or cortisol patterns. Mood and cognitive concerns may have hormonal contributors that a basic panel would not reveal.
By evaluating all three systems together, Dr. Kosubevsky can look for patterns and interactions that a single-system test might miss—providing a more complete foundation for any wellness recommendations that follow.
For individuals experiencing ongoing tiredness that does not improve with rest, and whose standard bloodwork has returned within normal ranges.
For patients who have adjusted diet and exercise without expected results, and who want to evaluate whether hormonal factors may be contributing.
For those experiencing brain fog, irritability, anxiety, depressed mood, or disrupted sleep who want to explore potential hormonal contributors alongside their standard medical care.
For men and women experiencing shifts in sexual desire, function, or satisfaction that may have a hormonal component.
For patients considering hormone replacement therapy, peptide therapy, or other wellness services who need a comprehensive baseline before beginning any protocol.
For men and women in their 30s, 40s, 50s, and beyond who want to understand how their hormonal landscape may be shifting with age—and what, if anything, may warrant clinical attention.
