The Labs We Run and Why Each One Matters

One of the most common questions we hear before a first visit is some version of: what are you actually going to test? It's a fair question. If you've had bloodwork before and walked away with a vague "everything looks normal," it's reasonable to want to know what makes a hormone optimization workup different.

The short answer is that we look deeper, and we look at how everything connects. Hormones don't work in isolation — your thyroid, your blood sugar, your stress hormones, and your sex hormones all influence one another. So rather than checking a single number, we build a complete picture. Here's a plain-language tour of the labs we commonly run at Finger Lakes FNP and why each one earns its place.

(Not every person needs every test — your panel is tailored to your symptoms, your health history, and whether you're a man or a woman. Think of this as the toolbox, not a fixed checklist.)

Your sex hormones — the core of the picture

These are the hormones most people come to us thinking about, and for good reason.

For women, we often look at estradiol (your main estrogen), progesterone, testosterone (yes, women need it too), and DHEA-S, a building-block hormone made by your adrenal glands. Timing matters here — for cycling women, some of these are best drawn on specific days of your cycle to be meaningful, which is the kind of detail a rushed workup often misses. We may also check FSH and LH, two pituitary signals that help us understand where you are in the menopausal transition, and SHBG, a protein that binds hormones and quietly determines how much of your testosterone is actually available for your body to use.

For men, the anchors are total and free testosterone — total tells us how much you have, free tells us how much is actually usable. We pair these with estradiol (men need a healthy amount, but balance matters), DHEA-S, SHBG, and LH and FSH, which help us tell whether a low testosterone is coming from the testes or from signaling higher up in the brain.

Together, these paint the picture of not just whether a hormone is "low," but why — which is what actually guides good treatment.

Your thyroid — the metabolism thermostat

Thyroid problems hide behind so many hormone-like symptoms — fatigue, weight gain, brain fog, low mood — that we rarely evaluate hormones without looking here too.

We go beyond the single TSH most people have had before. TSH is really the brain's message to the thyroid, not the thyroid hormone itself, so we also look at Free T3 (the active hormone your cells actually use) and Free T4 (the reserve form your body converts into T3). When symptoms don't match the standard numbers, we may add Reverse T3, which can reveal when your body is essentially putting the brakes on its own thyroid function. And we often check thyroid antibodies (TPO and thyroglobulin), which uncover Hashimoto's — an autoimmune condition that's one of the most common and most missed reasons thyroid function slips. Crucially, we read these against an optimal range, not just the wide "normal" one, because feeling well and being technically in-range aren't always the same thing.

Blood sugar and insulin — the hidden root cause

This is the panel people are most surprised we run, and often the most important. Insulin resistance is one of the biggest hidden drivers of hormonal imbalance, weight that won't budge, and fatigue.

We look at hemoglobin A1c, your three-month blood sugar average, and often fasting insulin, which can flag a problem years before blood sugar itself ever looks abnormal. We usually add a lipid panel (cholesterol and triglycerides), since metabolic and hormonal health are deeply intertwined and this also helps us keep an eye on your cardiovascular picture. Addressing this layer is often what makes everything else — including hormone therapy — work better.

Your foundational health and safety labs

Good hormone care is as much about safety as optimization, and these routine-but-essential tests are how we make sure your plan is built on solid ground.

A CBC (complete blood count) checks your red and white blood cells — and for men on testosterone therapy, it's how we monitor hematocrit, since testosterone can thicken the blood and that needs watching. A CMP (comprehensive metabolic panel) checks your kidney and liver function and key electrolytes, confirming your body can safely process the therapies we might use. For men, we also run PSA before and during testosterone therapy — a prostate safety check that's simply non-negotiable for responsible care.

The extra markers that fill in the story

Depending on your symptoms, we may reach for a few more targeted tests. Vitamin D is one we check often, because it behaves more like a hormone than a vitamin and is tied to everything from energy to testosterone to immune health. We may look at inflammation and related markers like CRP, ferritin, homocysteine, or uric acid when the clinical picture calls for it, and B12 when fatigue or nerve symptoms are in play. When stress, "tired but wired" energy, or burnout are part of the story, we may also assess cortisol, your primary stress hormone, since chronically high or depleted cortisol can quietly sabotage all your other hormones.

Why all of this matters to you

Here's the thread running through every one of these tests: we're not chasing a single number, and we're not here to tell you you're "fine" while you clearly don't feel it. We run a thorough panel so we can see how your systems work together, catch the root causes that a basic workup misses, keep your treatment safe, and give us a real baseline to measure your progress against as you start to feel better.

It's also why we read your labs alongside your symptoms, never in isolation. Your numbers tell part of the story — how you feel tells the rest.

If you've been frustrated by bloodwork that raised more questions than it answered, this is the kind of thorough, connect-the-dots evaluation we do every day.
