Most patients who come to us for hormone optimization have already had bloodwork done somewhere else. They arrive with a single page from an annual physical showing a total testosterone number, a TSH, maybe a cholesterol panel, and they've been told everything looks "normal." Then they ask the obvious question: if everything is normal, why do I feel like this?
The answer, almost always, is that the panel was too narrow. A proper hormone workup looks at the entire endocrine conversation, not one or two shouted words from it. Below is what we actually track in our practice, what each marker tells us, and why the number on the page is only the starting point.
The Sex Hormone Panel: Far More Than Total Testosterone
Total testosterone is useful. On its own, it's also misleading. We routinely see men with "normal" total testosterone around 500 ng/dL who feel exhausted, flat, and sexually disinterested. The reason usually shows up in the free and bioavailable numbers, which measure what your tissues can actually use.
What we order for men
- Total and free testosterone (free measured directly or calculated with SHBG and albumin)
- Sex hormone binding globulin (SHBG), which rises with age, alcohol intake, and thyroid shifts and can lock up otherwise adequate testosterone
- Estradiol, measured by the sensitive assay, not the standard immunoassay built for women
- LH and FSH to distinguish primary testicular issues from pituitary signaling problems
- DHEA-sulfate, an adrenal precursor that often drops meaningfully by the mid-40s
- Prolactin, because elevations here can suppress the entire axis and occasionally signal a pituitary adenoma
- PSA before and during optimization, as a baseline and a safety marker
What we order for women
Timing matters. For cycling women, we draw on specific cycle days when possible. For perimenopausal and postmenopausal women, timing is less rigid but still worth planning.
- Estradiol and progesterone, interpreted against cycle phase or menopausal status
- Total and free testosterone with SHBG, because women make and need testosterone too, and oral contraceptives can drive SHBG sky-high
- FSH and LH to confirm where someone sits in the menopausal transition
- DHEA-sulfate
- Prolactin, particularly with cycle irregularity or galactorrhea
- AMH when ovarian reserve is clinically relevant
Thyroid: The Panel Almost Nobody Runs Completely
TSH alone is the single most overused thyroid test in American medicine. It tells you what the pituitary thinks about your thyroid. It does not tell you what hormone is actually circulating or whether your cells can convert and use it.
A complete thyroid panel includes TSH, free T4, free T3, reverse T3, and both thyroid antibodies (TPO and thyroglobulin). We've picked up early Hashimoto's in dozens of patients whose TSH was textbook normal but whose antibodies were climbing. We've also seen the mirror image: patients on levothyroxine with a perfect TSH who felt terrible because their free T3 was at the floor of the range and reverse T3 was elevated, suggesting poor peripheral conversion. You cannot see any of that from a TSH alone.
Metabolic Markers: Where Hormones Meet Everyday Physiology
Hormones don't operate in a vacuum. Insulin resistance blunts testosterone production in men and drives androgen excess in women. Inflammation suppresses the HPA axis. Fatty liver changes how estrogens are metabolized. Any serious hormone workup includes:
- Fasting insulin and glucose, with HOMA-IR calculated. We often see fasting insulin in the teens while glucose looks pristine, which is the earliest fingerprint of metabolic dysfunction.
- Hemoglobin A1c
- Comprehensive metabolic panel for liver and kidney function
- Lipid panel with ApoB and Lp(a). ApoB counts the actual atherogenic particles. Lp(a) is largely genetic, measured once in a lifetime, and changes the risk conversation entirely when elevated.
- hs-CRP as a general inflammation marker
- GGT, an underused signal of liver stress and oxidative load
The Supporting Cast: Nutrients and Cofactors
Hormone synthesis is a biochemical assembly line, and it needs raw materials. We check:
- Vitamin D (25-OH), aiming for a mid-range level rather than scraping the lower limit
- Ferritin and a full iron panel, especially in menstruating women and in men who train hard or donate blood
- B12 and folate
- Magnesium (RBC, not serum, when possible)
- Zinc, which supports testosterone production and immune function
- Homocysteine, a methylation and cardiovascular marker
A testosterone level that won't budge despite a solid protocol often traces back to a ferritin of 20 or a vitamin D of 18. Fix the substrate problem and the hormonal picture frequently improves on its own.
Cortisol and the Stress Axis
If you sleep poorly, wake unrefreshed, and crash in the afternoon, your sex hormone numbers may be downstream of a cortisol problem. A morning serum cortisol is a reasonable starting point. When the clinical picture warrants, we add a four-point salivary cortisol or a DUTCH test to map the diurnal rhythm. Treating testosterone while ignoring a flat cortisol curve rarely produces the outcome patients are hoping for.
Safety Monitoring Once You're on a Protocol
Starting hormone optimization is not the end of lab work. It's the beginning of a different cadence. For men on testosterone, we typically recheck at six to eight weeks, then quarterly for the first year, then every six months once stable. The monitoring panel includes:
- CBC, specifically hematocrit, because testosterone can thicken the blood and occasionally requires dose adjustment or therapeutic phlebotomy
- Estradiol, since aromatization varies widely between individuals
- PSA at baseline, three months, and annually thereafter
- Lipids and metabolic markers, which usually improve but should be verified
- Trough and sometimes peak testosterone levels, timed to the injection or application schedule
For women, follow-up labs depend on the route and dose, but the principle is identical: measure, adjust, measure again. Symptoms guide the dose. Labs confirm safety and context.
How to Read Your Own Results
Two practical points worth internalizing. First, "within range" is not the same as optimal. Reference ranges are built from population averages that include a lot of unwell people. A free testosterone at the 5th percentile is technically normal and clinically miserable. Second, trends matter more than single values. A testosterone that has dropped from 900 to 450 over five years tells a very different story than a stable 450, even though only one number appears on today's report.
This is also why we discourage patients from chasing numbers in isolation. The goal is not a specific estradiol value or a perfect free T3. The goal is a person who sleeps well, thinks clearly, trains without undue soreness, has a libido that matches their partner's, and whose cardiovascular and metabolic risk is moving in the right direction. Labs are the map. You are the territory.
What to Ask For
If you're evaluating a hormone optimization program, ask what their baseline panel includes before you commit. If the answer is testosterone, TSH, and a CBC, keep looking. A thoughtful workup takes more vials, costs more up front, and spares you months of guessing later.
If you'd like a comprehensive baseline evaluation and a protocol built around what your labs actually show, contact our team to request a consultation. We'll review your history, order the right panel the first time, and walk through every number with you in plain language.
