THE COMPLETE FEMALE HORMONE TESTING CHECKLIST

Lab Tests I Actually Order as a Naturopathic Doctor

If you're struggling with fatigue, weight gain, PMS, acne, hair loss, irregular periods, infertility, anxiety, low libido, or perimenopause symptoms, you've probably wondered whether your hormones are to blame.

The challenge is that many women are told their hormones are "normal" after completing only a handful of basic blood tests. Unfortunately, hormones don't operate in isolation. They are influenced by your thyroid, metabolism, nutrient status, gut health, inflammation levels, and even how your body responds to stress.

One of the biggest mistakes I see is women spending hundreds of dollars on supplements without first understanding what's actually driving their symptoms.

Testing allows us to move beyond guessing and identify the root cause.

Below is the female hormone testing checklist I commonly use in practice when investigating hormone-related concerns.

1. Thyroid Testing

Markers I Commonly Assess

✓ TSH

✓ Free T4

✓ Free T3

✓ Reverse T3

✓ Thyroid Peroxidase Antibodies (TPOAb)

✓ Thyroglobulin Antibodies (TgAb)

Why These Markers Matter

Your thyroid acts like the thermostat for your metabolism.

Every cell in your body relies on thyroid hormones to determine how much energy it produces. When thyroid function slows down, it can affect virtually every system in the body.

Women with thyroid dysfunction commonly experience:

• Fatigue

• Weight gain

• Hair loss

• Constipation

• Depression

• Brain fog

• Irregular periods

• Fertility challenges

Many women are told their thyroid is normal because their TSH falls within range. However, TSH is only one piece of the puzzle. A more comprehensive assessment can uncover autoimmune thyroid disease, poor conversion of T4 into active T3, or early thyroid dysfunction before it becomes obvious on standard testing.

2. Female Hormone Testing

Markers I Commonly Assess

✓ Estradiol (E2) - day 3

✓ Progesterone - 5-7 days post ovulation (you cannot test progesterone in your follicular phase)

✓ Testosterone

✓ Free Testosterone

✓ DHEA-S

✓ SHBG

✓ LH

✓ FSH

✓ Prolactin

✓ Anti-Müllerian Hormone (AMH)

Why These Markers Matter

These are the hormones most women think about when they hear the phrase "hormone imbalance."

They influence:

• Menstrual cycles

• Ovulation

• Fertility

• Mood

• Energy

• Libido

• Skin health

• Muscle mass

• Perimenopause symptoms

What's important is that hormones rarely become imbalanced without a reason. While identifying abnormal estrogen, progesterone, or testosterone levels is helpful, understanding why they became abnormal is often where the real answers are found.

3. Blood Sugar & Insulin Resistance Testing

Markers I Commonly Assess

✓ Fasting Glucose

✓ Fasting Insulin

✓ Hemoglobin A1c

✓ ApoB

✓ Triglycerides

✓ HDL Cholesterol

Why These Markers Matter

Most women associate blood sugar problems with diabetes.

In reality, insulin is one of the most powerful hormones in the body and plays a major role in reproductive health.

Elevated insulin levels can contribute to:

• PCOS

• Infertility

• Weight gain

• Cravings

• Hormonal acne

• Elevated testosterone

• Chronic inflammation

One of the most overlooked findings in practice is insulin resistance in women who have completely normal glucose levels.

Testing insulin early often identifies metabolic dysfunction years before diabetes develops.

4. Iron & Energy Testing

Markers I Commonly Assess

✓ Ferritin

✓ Iron

✓ Total Iron Binding Capacity (TIBC)

✓ Transferrin Saturation

✓ Complete Blood Count (CBC)

Why These Markers Matter

Not every symptom that feels hormonal is actually hormonal.

Iron deficiency is one of the most common causes of fatigue, hair loss, brain fog, and poor exercise recovery in women.

Ferritin, which reflects stored iron, is one of my favourite markers because low levels can contribute to symptoms long before anemia develops.

Many women are told their CBC is normal despite having ferritin levels that may be contributing to significant symptoms.

5. Nutrient Status Testing

Markers I Commonly Assess

✓ Vitamin D

✓ Vitamin B12

✓ Folate

✓ Zinc

✓ RBC Magnesium

✓ Homocysteine

Why These Markers Matter

Hormones are built from nutrients.

If your body lacks the nutrients required to produce, metabolize, and detoxify hormones efficiently, symptoms can develop regardless of what your hormone levels look like on paper.

Deficiencies may contribute to:

• Fatigue

• Hair loss

• Anxiety

• Depression

• Fertility challenges

• Poor stress resilience

• Impaired hormone production

One marker I particularly like is homocysteine because it provides insight into methylation, a process involved in estrogen metabolism, detoxification, cardiovascular health, and neurotransmitter production.

6. Inflammation Testing

Markers I Commonly Assess

✓ High Sensitivity C-Reactive Protein (hs-CRP)

✓ ESR

✓ Fibrinogen

Why These Markers Matter

Inflammation is one of the most common drivers of chronic disease and hormone dysfunction.

Low-grade inflammation can influence:

• Estrogen metabolism

• Insulin sensitivity

• Ovulation

• Thyroid function

• Autoimmune disease

• Fertility outcomes

Many women don't realize that inflammation can exist for years before symptoms become severe enough to trigger a diagnosis.

Identifying and addressing inflammation early can have significant impacts on long-term health.

7. Gut Health Testing

   
   

Markers I Commonly Assess

✓ β-Glucuronidase

✓ Calprotectin

✓ Secretory IgA

✓ Zonulin

✓ Pancreatic Elastase

✓ Short Chain Fatty Acids

✓ Akkermansia spp.

✓ Faecalibacterium prausnitzii

✓ Microbial Diversity Score

✓ H. pylori

✓ Yeast & Fungal Assessment

Why These Markers Matter

Your gut does much more than digest food.

It plays a major role in:

• Estrogen metabolism

• Immune regulation

• Nutrient absorption

• Inflammation control

• Neurotransmitter production

One of my favourite markers is β-Glucuronidase.

Think of estrogen detoxification like taking out the garbage.

Your liver packages estrogen for elimination. Elevated β-Glucuronidase can reopen that package and allow estrogen to be reabsorbed back into circulation.

This may contribute to symptoms such as:

• PMS

• Heavy periods

• Breast tenderness

• Hormonal acne

• Estrogen dominance symptoms

I also pay close attention to beneficial bacteria such as Akkermansia and Faecalibacterium, as well as overall microbial diversity, because these organisms play important roles in inflammation regulation, gut barrier integrity, and metabolic health.

8. DUTCH Hormone Testing

Markers Assessed in a DUTCH Hormone Test:

✓ Estrone (E1)

✓ Estradiol (E2)

✓ Estriol (E3)

✓ Progesterone Metabolites

✓ Testosterone Metabolites

✓ DHEA Metabolites

✓ Cortisol Metabolites

✓ Cortisone Metabolites

✓ 2-OH Estrogen

✓ 4-OH Estrogen

✓ 16-OH Estrogen

✓ Methylation Markers

Why These Markers Matter

The DUTCH Test goes beyond measuring hormone levels.

It allows us to understand how your body is processing and metabolizing hormones.

This is particularly useful for women experiencing:

• PMS

• Estrogen dominance

• Hormonal acne

• Fertility concerns

• Perimenopause symptoms

• Unexplained hormone-related symptoms despite normal bloodwork

In many cases, the issue isn't how much estrogen you're producing—it's how you're metabolizing and eliminating it.

Why I Rarely Order Cortisol Testing

This often surprises patients.

While cortisol is an important hormone, I don't routinely place significant emphasis on cortisol blood testing.

Cortisol is one of the most dynamic hormones in the body. Levels can fluctuate dramatically based on:

• Sleep quality

• Emotional stress

• Exercise

• Blood sugar fluctuations

• Illness

• Caffeine intake

• Menstrual cycle phase

• Even anxiety about having blood drawn

A single cortisol measurement often provides very little insight into how your body is handling stress day-to-day.

Instead, I prefer to evaluate how stress is impacting the body in real time.

What I Find More Useful

I often encourage patients to use wearable technology such as:

• Oura Ring

• WHOOP

• Ultrahuman Ring

Key metrics I pay attention to include:

✓ Resting Heart Rate (RHR)

✓ Heart Rate Variability (HRV)

✓ Sleep Duration

✓ Sleep Quality

✓ Recovery Metrics

Why Resting Heart Rate Matters

Your resting heart rate can act as a real-time stress biomarker.

When the body is under increased stress from poor sleep, overtraining, illness, under-eating, inflammation, or emotional stress, resting heart rate often rises before symptoms become obvious.

Why Heart Rate Variability Matters

HRV reflects how adaptable and resilient your nervous system is.

Generally speaking:

• Higher HRV = greater recovery and resilience

• Lower HRV = greater physiological stress

In many cases, tracking these metrics over months provides significantly more actionable information than a single cortisol measurement.

The Bottom Line

There is no single hormone test that works for every woman.

The most effective approach is identifying which systems are contributing to your symptoms and selecting the appropriate testing accordingly.

In practice, I rarely find a hormone issue that exists in isolation. More often, symptoms are influenced by a combination of thyroid function, metabolic health, nutrient status, gut health, inflammation, and lifestyle factors.

Testing helps us stop guessing and start building a treatment plan based on data.

If you're struggling with hormone-related symptoms and want a personalized assessment, booking a comprehensive hormone evaluation is often the first step toward understanding what's really going on beneath the surface.
