Functional Lab Testing
Functional lab testing for perimenopause and menopause. A deeper look at what's actually driving your symptoms.
Test, Don't Guess
As a functional registered dietitian with advanced training in lab interpretation, I can order functional lab testing directly. No referral needed. This becomes especially important during perimenopause, when symptoms like fatigue, brain fog, weight changes, and cycle irregularities are often written off as "just hormones." In reality, many of these symptoms overlap with thyroid dysfunction, metabolic changes, or nutrient deficiencies.
Advanced lab testing helps us separate what's truly hormonal from what's not, catch early shifts in metabolism and cardiovascular risk, and identify deficiencies that are common during this stage. It also gives us a more complete picture over time, so we're not making decisions based on a single snapshot. The result is a plan grounded in your data, targeted to your physiology, and built to support both how you feel now and your long-term health.
Tests I Work With
-
A comprehensive hormone test that goes beyond standard bloodwork. The DUTCH Complete evaluates not just estrogen and progesterone levels, but how your body metabolizes and clears them. It provides insight into estrogen detoxification pathways, daily cortisol patterns, androgens, and melatonin for a more complete picture of hormone function. It's especially helpful for women on hormone replacement therapy (HRT) who are still experiencing symptoms, because it shows not just how much hormone is present, but how your body is processing it.tion text goes here
-
A stool test that uses DNA analysis to evaluate your gut microbiome, opportunistic and pathogenic organisms, and key markers of intestinal health, including inflammation and permeability. This is particularly relevant in perimenopause and menopause, when shifts in the gut microbiome can directly influence hormone balance. The gut plays a central role in estrogen metabolism through the estrobolome, which affects how estrogen is processed and recirculated in the body. Understanding what's happening in your gut lets us connect digestive health, hormone balance, and metabolic function, so interventions are targeted rather than guesswork.
-
Measures your omega-3 levels and the balance of omega-3 to omega-6 fatty acids in your red blood cell membranes, reflecting what your body has actually absorbed and incorporated rather than just what you eat. This provides insight into inflammation and cardiovascular risk, offering a more functional perspective than a standard lipid panel alone. It's particularly relevant during perimenopause and menopause, when hormonal shifts can increase inflammation and affect metabolic health.

Standard bloodwork often stops at a basic metabolic panel and a TSH. I look deeper, because early metabolic and thyroid changes are some of the most common and most missed drivers of symptoms in perimenopause and menopause. Metabolic markers: Fasting insulin, fasting glucose, and HbA1c. Insulin resistance often rises during perimenopause and can show up years before blood sugar or A1c move out of the normal range. Fasting insulin is one of the earliest signals, and together with fasting glucose it lets us calculate HOMA-IR, a measure of insulin resistance. Catching these shifts early is key to addressing weight gain around the midsection, energy crashes, and long term cardiometabolic risk. Thyroid markers: TSH, free T4, and free T3, plus reverse T3 and thyroid antibodies (TPO and thyroglobulin) when indicated. TSH alone doesn't tell the full story. Free T4 shows how much thyroid hormone your body is producing, and free T3 shows how much is being converted into the active form your cells actually use. Thyroid symptoms like fatigue, weight changes, hair thinning, and brain fog overlap heavily with perimenopause, so a complete panel helps us tell the difference and target the right root cause. I interpret these results using optimal ranges, not just the standard reference ranges, so we can spot meaningful patterns before they become a diagnosis.
-
A detailed assessment of body composition, including lean mass, fat mass, and muscle distribution, using bioelectrical impedance. This is especially valuable during perimenopause, when hormonal shifts can lead to muscle loss and increased visceral fat, changes that weight and BMI alone can't capture. DEXA scans are considered the clinical gold standard for body composition and bone density; InBody offers a practical, accessible way to track meaningful changes consistently. I recommend an InBody scan every 4 to 6 weeks when you're actively working toward body composition goals, and every 3 to 6 months during maintenance.
A Note on Cost
Functional lab tests are typically not covered by insurance and are paid out of pocket. Costs vary by test and lab. I'll always discuss whether testing is clinically indicated for your situation before recommending it, and I never order tests just for the sake of ordering them. My session fees, where I interpret your results and build your protocol, are typically covered by insurance through Berry Street. Testing is always personalized to your symptoms, history, and goals. Not every test is right for every client, and recommendations are made thoughtfully so the data we gather directly informs your care.
Already have results?
If you've done a DUTCH, GI-MAP, or other functional panel through another provider and aren't sure what to do with the findings, I offer interpretation and protocol development as part of your ongoing care. Bring what you have, and we'll work from there.
Not sure if testing is right for you?
Rest assured. We'll figure that out together in your first session.
