Marker by marker — what low and high can look like, and why patterns tell you more than any single value.
Sep 2026 · Four minutes.
This is a companion to keep beside your results — a plain-language note on what each marker tends to reflect, so you can bring better questions to the clinician who ordered them.
The same caution I always give: I do not diagnose from labs and I do not replace your healthcare team. Interpretation belongs with the clinician who knows your history. What follows is context, not a conclusion.
Low can look like hot flashes, brain fog, vaginal dryness, and joint pain. High — which happens during perimenopausal fluctuation — can look like heavy bleeding, breast tenderness, and migraines.
Watch for patterns rather than single values.
Low can look like anxiety, PMS, spotting, insomnia, and the cluster often described as estrogen dominance. After menopause it is expected to be low unless you are on hormone therapy.
Its ratio to estrogen matters more for how you feel than the number alone.
Low can look like low libido, low motivation, poor muscle retention, and fatigue. High, before menopause, can look like acne, hair growth, and PCOS-like changes.
Free testosterone is often more telling than total.
Low can look like fatigue, burnout, and low resilience. High can reflect androgen excess or a heavy stress load. It supports adrenal and hormonal reserve.
High suggests ovarian decline, in late perimenopause moving toward menopause. Widely fluctuating values suggest early to mid perimenopause.
Neither is useful for tracking a cycle during perimenopause.
High can look like wired-tired, anxiety, and hot flashes that worsen with stress. Low can look like burnout, exhaustion, crashes, and low blood pressure.
Saliva or DUTCH patterns give better insight than a single morning draw.
Low thyroid function mimics menopause symptoms closely enough that it is worth ruling out. TSH is often discussed as optimal between 1.0 and 2.0 rather than simply inside the reference range. Free T3 is your metabolic engine.
Often discussed as optimal between 40 and 60 ng/mL for immunity, mood, and bone. Low levels tend to worsen fatigue and hormonal symptoms.
Often discussed as optimal below 1.0. Elevated suggests inflammation, stress load, or metabolic strain.
I look at these together, not one at a time, and alongside what you are actually experiencing — sleep, energy, recovery, training, nourishment. A number that sits inside the reference range can still sit far from where you feel well. And a number on its own, without the pattern around it, rarely tells us much.
Bring your results. Bring your questions. We will look at the whole picture, and you will leave with better questions for the clinician who ordered them.
