Hormone Testing

(Advanced Hormone Function Analysis)

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.

Important Notice

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.

Three Systems, One Evaluation

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 & Reproductive Markers

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).

Thyroid Cascade

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.

Adrenal & Stress Axis Markers

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.

Why a Multi-System Approach Matters

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.

Who This Testing Is For

Persistent Fatigue or Low Energy

For individuals experiencing ongoing tiredness that does not improve with rest, and whose standard bloodwork has returned within normal ranges.

Weight Changes Resistant to Lifestyle Efforts

For patients who have adjusted diet and exercise without expected results, and who want to evaluate whether hormonal factors may be contributing.

Mood, Sleep, or Cognitive Concerns

For those experiencing brain fog, irritability, anxiety, depressed mood, or disrupted sleep who want to explore potential hormonal contributors alongside their standard medical care.

Libido or Sexual Wellness Changes

For men and women experiencing shifts in sexual desire, function, or satisfaction that may have a hormonal component.

Pre-Optimization Baseline

For patients considering hormone replacement therapy, peptide therapy, or other wellness services who need a comprehensive baseline before beginning any protocol.

Age-Related Wellness Planning

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.

Why Choose Dr. Kosubevsky?

Dr. Benjamin Kosubevsky combines conventional medical training with advanced experience in integrative, regenerative, and osteopathic medicine. Patients working with Dr. Kosubevsky receive:

Physician-Interpreted Results: Every hormone panel is personally reviewed by Dr. Kosubevsky in the context of your symptoms, health history, and wellness goals—not reduced to an automated reference-range comparison.
Multi-System Perspective: An integrative approach that considers how thyroid, adrenal, and sex hormone systems interact rather than evaluating each in isolation.
Clinical Context Over Lab Ranges: Standard laboratory reference ranges reflect statistical norms across large populations. Dr. Kosubevsky interprets your results in the context of your individual presentation, recognizing that values within “normal” ranges may still warrant clinical discussion.

Understand What Your Hormones Are Actually Telling You

The Advanced Hormone Function Analysis at The Longevity Center FL provides a more complete picture of your endocrine health than a standard hormone screen. Whether you are trying to understand why you feel the way you do, or building a baseline before starting a wellness program, this evaluation provides the data and clinical context to support more informed decisions.

Frequently Asked Questions

The clinic offers comprehensive hormone panels covering thyroid, adrenal, sex hormones, insulin, cortisol, DHEA, and metabolic hormones. Testing may use blood, saliva, or urine samples depending on which hormones are being evaluated and whether daily rhythm matters. Advanced options such as DUTCH metabolite testing may also be available for a deeper view of how hormones are processed. The goal is to identify imbalances contributing to fatigue, weight changes, mood issues, low libido, and sleep disturbances so therapy can be targeted rather than empiric.

Some panels require morning fasting, and others require timed collections, such as saliva samples taken at four specific points across the day to map your cortisol curve. Women of cycling age may need collection on a specific cycle day for accurate progesterone and estradiol readings. The clinic provides detailed prep instructions when your tests are ordered. Following them closely matters, since improper timing is the most common reason results need to be repeated at additional cost.

Yes. Low testosterone, estrogen or progesterone imbalance, thyroid dysfunction, blunted or elevated cortisol, and low DHEA are common contributors to both fatigue and low libido. Testing helps pinpoint which systems actually need support, so therapy is targeted rather than guesswork. Depending on findings, interventions may include bioidentical hormone replacement, adrenal support, thyroid optimization, or lifestyle changes. Because fatigue and low libido have many possible causes, hormone testing is typically interpreted alongside iron studies, sleep quality, and metabolic markers.

Blood draws are completed in a partnered lab. Saliva and urine kits are usually completed at home on a specified schedule and mailed directly to the lab. The method depends on the hormone being tested: cortisol is often measured by saliva to capture its daily rhythm, sex and thyroid hormones are typically blood-based, and metabolite panels such as DUTCH use dried urine. The clinic provides written collection instructions with each kit.

Most results return within 5 to 14 days, depending on the lab and the complexity of the panel. Conventional blood panels tend to return faster than specialty saliva or dried-urine metabolite testing. A follow-up visit is scheduled to review findings and discuss therapy options, and the provider walks through what each result means and how it fits into your overall plan rather than simply handing over a report. You receive copies of your results for your own records.

The clinic is able to bill your insurance for hormone testing; however, coverage is determined by your plan and provider. We also have cash pay options available.

Yes. Men's hormone panels commonly evaluate total and free testosterone, SHBG, estradiol, DHEA, cortisol, PSA where appropriate, and thyroid function. These tests help identify andropause, metabolic dysfunction, and the causes behind symptoms such as low energy, low libido, muscle loss, and poor recovery. Depending on results, options include testosterone replacement therapy, targeted lifestyle changes, or addressing an upstream issue such as sleep apnea or insulin resistance that may be suppressing hormone production.

Yes. The clinic provides cycling or postmenopausal hormone panels to guide bioidentical hormone replacement. Symptoms such as hot flashes, night sweats, mood changes, brain fog, sleep disruption, and vaginal dryness can be addressed more precisely once your hormone patterns are understood. For women still cycling, collection timing is matched to your cycle for accuracy. Therapy decisions weigh your personal and family history, and your provider reviews risks and benefits with you before starting therapy.

Yes, the clinic offers DUTCH testing. The DUTCH test is an advanced dried-urine hormone metabolite panel that shows not only your hormone levels but how your body processes estrogen, progesterone, testosterone, cortisol, and melatonin. It reveals detoxification patterns and cortisol rhythm that standard blood panels cannot capture, which makes it useful when symptoms persist despite normal-looking bloodwork. Your provider will determine whether DUTCH or a conventional panel better fits your evaluation, since it is not needed for every patient.

Results are used to design hormone optimization, lifestyle, or supplement protocols tailored to your findings, but therapy is not automatic. If results are within a healthy range, the provider may look elsewhere for the cause of your symptoms rather than prescribing hormones. If hormone replacement is appropriate, your provider discusses risks, benefits, monitoring requirements, and administration options before you start, and follow-up labs confirm you are responding as expected.
