The 12 Hormone Labs Every Woman Should Ask For at Her Annual Exam (Perimenopause + Menopause Guide)
“Normal” lab results don’t mean your body is functioning well. They mean you haven’t crossed a disease threshold—yet. Most lab reference ranges are based on statistical averages—not a woman’s optimal physiology.
They’re not built around how you want to feel throughout life. Increased, sustainable energy. Deep, restful sleep. Improved body composition. Clear, focused thinking.
So, when your practitioner tells you everything looks normal, but you still feel less than 50%, it’s time to get the proper care and assessment you deserve.
Traditional lab values measure you against an outdated, generalized standard.
We can do better.
If you’re searching for hormone testing in West Loop Chicago or throughout Illinois or trying to understand which labs to request during perimenopause or menopause, this guide breaks down the panel most often used at Peacock Health Collective.
At Peacock Health Collective in Chicago, Illinois, this is where the Women’s Health Assessment shifts you from standard care to concierge healthcare built around a woman’s unique physiology.
We don’t rely on basic panels. We use a more comprehensive set of labs—looking at thyroid, metabolism, iron, nutrients, and hormones—to create a full picture of how your body is actually functioning.
We offer both in-person appointments in West Loop Chicago and virtual care across Illinois, so you can access this level of care in a way that fits your life.
The 12 Foundational Labs for Hormone Testing in Women
These are the 12 labs offered inside the Women’s Health Assessment at Peacock Health Collective, with additional markers layered in depending on your stage of life.
Thyroid Function
TSH
Free T4
Free T3
TPO Antibodies
Metabolic Health + Blood Sugar
Fasting Glucose
Fasting Insulin
Hemoglobin A1C
Iron Status
Ferritin
Iron Panel (Iron + TIBC)
Nutrient Status

Women in midlife deserve healthcare that reflects their physiology—not a one-size-fits-all approach your practitioner learned in school.
What I Add Based on You: Advanced Hormone Testing
Because no two women present the same way, I often expand this panel to include:
FSH
LH
DHEA-S
SHBG
Total Testosterone
Free Testosterone
This is where we move from basic lab work into actual specialized hormone medicine.
Thyroid Testing for Women in Perimenopause and Menopause
This is one of the most overlooked systems in midlife women—and one of the most important.
TSH tells us how hard your brain is signaling your thyroid to work. It’s useful, but it’s not the full story. The TSH has a large range of what practitioners may consider as “normal” we narrow that value and also look at the other thyroid markers.
Free T4 shows what your thyroid is producing.
Free T3 shows what your body is using.
You can have a normal TSH and still have symptoms if your body isn’t converting or utilizing hormone efficiently.
TPO antibodies help identify autoimmune thyroid patterns, which are common in women and often show up during hormonal transitions or in undiagnosed conditions like Hashimoto’s thyroiditis.
Perimenopause context
Estrogen fluctuations, stress, and poor sleep all impact thyroid function and conversion. Many symptoms get labeled as hormonal when thyroid is part of the picture. Proper assessment is essential to clarify your medical picture.
Menopause and hormone therapy context
Hormone therapy—especially estrogen—can shift thyroid binding and availability. Therefore, your practitioner may need to adjust your thyroid medication when introducing hormone therapy into your routine.
Hormone Testing in Perimenopause: Estradiol and Progesterone
This is where most women are told everything looks normal—while clearly feeling otherwise.
Estradiol is your primary estrogen. It fluctuates significantly in perimenopause.
These fluctuations can lead to:
Irregular periods
Hot flushes
Night sweats
Mood swings
Insomnia
Progesterone is your calming hormone and is often the first to decline.
Low levels can show up as:
Poor sleep
Irritability
Anxiety
Cycle irregularity
Perimenopause context
During the perimenopause transition, hormones become more inconsistent with progesterone being the first hormone to take a nose dive. Ovulation becomes less predictable, which changes how you feel month to month.
Menopause and hormone therapy context
BHRT helps to stabilize hormone levels, but symptoms still guide treatment decisions.
Metabolic Health and Insulin Resistance in Midlife Women
This is one of the biggest drivers of weight gain, fatigue, and hormone imbalance. Fasting glucose gives a snapshot. Fasting insulin tells us how hard your body is working behind the scenes.
You can have normal glucose and still have elevated insulin.
Insulin resistance can show up as
Weight gain
Cravings
Energy crashes
Skin changes
Hemoglobin A1C gives a longer-term view of blood sugar patterns taking into consideration the last 2-3 months.
Perimenopause context
As estrogen fluctuates, insulin sensitivity declines. This can show up as unexpected body composition changes—even when lifestyle stays the same.
Menopause and treatment context
Insulin resistance becomes more persistent. GLP-based therapies and metabolic support can improve these markers—but still require monitoring.
Iron Deficiency and Fatigue in Perimenopause
Low iron is one of the most common—and missed—reasons women feel exhausted. Ferritin reflects your stored iron.
Low levels are often linked to:
Fatigue
Hair thinning
Brain fog
Sensitivity to temperature (feeling cold)
The iron panel helps assess how iron is circulating and being used. Most menstruating women show with iron deficient anemia.
Perimenopause context
Heavy or irregular cycles can gradually deplete iron stores. Proper assessment is essential to a vibrant, energy filled days.
Menopause context
Iron may stabilize, but deficiencies often persist if they were never addressed. Nutrition and supplementation is key.
Vitamin D and Nutrient Status in Women Over 35
Vitamin D plays a critical role in overall health and is often overlooked.
It impacts:
Mood
Immune function
Bone health
Hormone signaling
Appetite
Low levels are extremely common in women over 35 and often contribute to fatigue and low mood.
Advanced Hormone Markers: DHEA-S, SHBG, and Testosterone
Hormone health is not just about estrogen. DHEA-S reflects adrenal function and hormone reserve. Low levels can contribute to low energy, reduced resilience, and decreased libido.
SHBG determines how much hormone is available to your body. You can have normal hormone levels—but if they are bound, they are not usable in your body systems.
Testosterone plays a critical role in women’s health. Testosterone is overlooked for its importance in a woman’s body. Testosterone is one of the most available hormones in a young woman and essential for a balanced life.
It impacts:
Energy
Muscle mass
Motivation
Libido
Cognitive clarity
Total testosterone shows how much is circulating. Free testosterone shows what is available for your body to use.
Why this matters
This is often where symptoms and labs don’t match—and where deeper analysis becomes essential.
