Your doctor runs blood work, checks your hormone levels, and tells you everything is “normal.” But you still feel terrible — tired, moody, gaining weight, not sleeping. The good news is that salivary hormone testing can idently hormone problems that blood testing often misses.
Here’s what most doctors don’t explain: over 99% of the hormones floating in your blood are inactive. They’re bound to carrier proteins, which means they can’t attach to your cells or do their job. A blood test measures all of those inactive hormones lumped together with the tiny fraction that’s actually working. So your “normal” blood result might be hiding the fact that your active hormone levels are way too low — or way too high.
Salivary hormone testing solves this problem. Saliva only contains the free, unbound hormones — the ones that are actually active in your body. That makes it the most accurate way to measure what your hormones are really doing, not just how many are floating around.
At Taylor Medical Group in Sandy Springs, salivary testing is a core part of how we manage bioidentical hormone replacement therapy (BHRT). It helps us get your dosing right, avoid overdosing, and make sure you’re getting the results you came for. We see patients from Atlanta, Dunwoody, Buckhead, Brookhaven, and Chamblee.

Blood Testing vs. Saliva Testing
Salivary Testing & Hormone Replacement
What Affects Your Active Hormone Levels
To understand why saliva testing is so useful, it helps to know a little about how hormones travel through your body.
Steroid hormones — estrogen, progesterone, testosterone, DHEA, and cortisol — are fat-soluble. They dissolve in oil, not water. But your blood is mostly water. So your body makes carrier proteins that wrap around these hormones so they can travel through the bloodstream. Think of it like putting a raincoat on something that can’t get wet.
The problem? While a hormone is wrapped in that carrier protein, it’s inactive. It can’t attach to a cell receptor. It can’t do anything. It’s just along for the ride.
Here’s a simple way to picture it: imagine a piece of candy still in its wrapper. If you put it in your mouth, you can’t taste anything — the wrapper blocks the flavor. That wrapper is the carrier protein. When the wrapper comes off, now you can taste it. That’s the “free” hormone — the active one — and that’s what shows up in your saliva.
Blood testing measures all the hormones — wrapped and unwrapped together. Salivary testing only measures the unwrapped ones. Since those are the only ones your body can actually use, saliva gives us the more useful number.
All three types of hormone testing give us different pieces of information. Here’s how they compare:
🩸 Blood Testing
Measures total hormone levels — both active and inactive combined. Useful for identifying generally low levels before starting treatment. But it doesn’t tell us how much hormone is actually available to your cells. Many doctors who rely only on blood tests end up guessing at dosage and adjusting based on symptoms alone.
💣 Salivary Testing
Measures active (free) hormone levels only. The most accurate method for determining what your hormones are actually doing and for setting the right dosage on hormone replacement therapy. This is the gold standard for monitoring BHRT — it catches overdosing and underdosing that blood tests miss.
🧬 Urine Testing (DUTCH)
Measures hormone metabolites — how your body breaks down and processes hormones. Useful for understanding estrogen metabolism pathways, cortisol patterns, and neurotransmitter status. We use the DUTCH test for this piece of the puzzle.
We often combine salivary testing with the DUTCH test to get both views — how much active hormone you have right now and how your body is metabolizing it. Together, they give us everything we need to fine-tune your treatment.
Our salivary hormone panels measure the active levels of:
Estrogen (Estradiol)
Controls your menstrual cycle, bone density, skin health, brain function, and mood. When estrogen drops during perimenopause and menopause, you get hot flashes, night sweats, vaginal dryness, brain fog, and mood swings. Too much estrogen causes bloating, breast tenderness, heavy periods, and weight gain. Salivary testing tells us exactly where you stand.
Progesterone
Your calming hormone. Progesterone helps you sleep, reduces anxiety, protects your uterine lining, and balances estrogen. Low progesterone is something we find constantly in our patients — and blood tests are notoriously unreliable for measuring it, especially oral progesterone. Saliva catches what blood misses.
Testosterone
Not just for men. Women need testosterone too — for energy, libido, muscle tone, bone strength, and mental clarity. Low testosterone in women often shows up as fatigue, zero sex drive, and a general feeling of “blah.” In men, it means low energy, brain fog, belly fat, muscle loss, and mood changes.
DHEA
Often called the “vitality hormone.” Your adrenal glands produce DHEA, and it’s a building block for both testosterone and estrogen. Low DHEA leads to fatigue, reduced immunity, aching muscles, depression, and loss of libido. It naturally declines with age — by 70, most people have only 10-20% of the DHEA they had at 25.
Cortisol
Your main stress hormone. Healthy cortisol should be high in the morning and low at night. Chronic stress flips this pattern — leaving you exhausted but wired, craving sugar, gaining weight around your middle, and unable to sleep. Salivary cortisol testing at multiple time points throughout the day maps your actual stress response.
Estrogen-to-Progesterone Ratio
Sometimes individual hormone levels look okay, but the ratio between them is off. Estrogen dominance — when estrogen is too high relative to progesterone — causes PMS, fibroids, heavy bleeding, weight gain, and mood issues. Saliva testing lets us calculate this ratio with the active hormones, which is far more accurate than blood.
We recommend salivary testing for anyone dealing with:
Perimenopause
Menopause
Andropause (Male)
PMS & PMDD
PCOS
Infertility
Post-Partum
Low Libido
Chronic Fatigue
Insomnia
Weight Gain
Adrenal Fatigue
We also use salivary testing for patients already on hormone therapy who need their levels monitored. If you’re on BHRT and your doctor has only been checking blood levels, your dosage might be off — and you wouldn’t know it. Salivary testing is the most reliable way to make sure your hormones stay in the right range. It’s a core part of our holistic medicine approach — test first, then treat.
This is where salivary testing really earns its keep. If you’re on bioidentical hormone replacement therapy, getting your dosage right is everything. Too little and your symptoms don’t improve. Too much and you get a whole new set of problems — headaches, bloating, breast tenderness, mood swings, or worse.
Many doctors prescribe BHRT based on blood testing alone. The problem is that blood measures total hormones — active and inactive combined. So a patient might have a “normal” blood level, but most of that hormone is bound up in carrier proteins and not doing anything. The doctor thinks the dose is right, but the patient still feels terrible.
Other doctors skip testing altogether and just go by symptoms. That’s even riskier — because many patients end up overdosed on hormones without knowing it. Hormone therapy is safe and effective when levels are maintained within normal limits. Too much or too little can both cause problems.
Salivary testing shows us exactly how much active hormone is available in your body after supplementation. That means we can dial your dose to the right level — not too much, not too little. We test before starting BHRT (to set your baseline), again 4-6 weeks in (to adjust dosing), and periodically after that to make sure things stay on track.
There are many things that shift the balance between active and inactive hormones in your body. This is exactly why you can’t guess — you have to test. Some of the biggest factors include:
Weight & Body Fat
Fat tissue produces and stores estrogen. More body fat means more active estrogen — which throws off the estrogen-to-progesterone ratio and can lead to estrogen dominance.
Diet
High-fat, low-fiber diets increase active estrogen levels because your body can’t clear excess estrogen through the gut. High-fiber diets help your liver and gut clear excess hormones more efficiently.
Chronic Stress
When your adrenals are constantly pumping out cortisol, your body “steals” from progesterone production to make more cortisol. This is called the pregnenolone steal — and it’s a major reason women in high-stress jobs develop hormone imbalances.
Environmental Estrogens
Pesticides on food, chemicals in cosmetics, plastics, and plant estrogens (phytoestrogens) can all act like estrogen in your body. These xenoestrogens add to your total estrogen load and throw off your hormone balance — even if your body’s own production is normal.
Blood Sugar & Insulin
Diabetes and insulin resistance increase how much free testosterone is available in women — which is why PCOS, acne, and facial hair often go hand in hand with blood sugar problems.
Exercise
Regular exercise helps your body process and clear hormones more efficiently. It also improves insulin sensitivity, which helps regulate testosterone and estrogen levels. On the flip side, extreme exercise can tank progesterone and suppress your menstrual cycle.
With this many variables in play, it’s impossible to know your active hormone levels without testing. That’s why we test — and why we test with saliva.

1
Consultation
We start with a thorough health history — your symptoms, menstrual history, stress levels, sleep, weight changes, and any hormone therapy you’re currently on. This helps us decide which hormones to test and when to collect your sample.
2
Collect at Home
You’ll get a saliva collection kit to use at home. No needles, no lab visit. Just spit into the collection tubes at the times we specify — usually morning, noon, evening, and bedtime for cortisol, or at a specific point in your menstrual cycle for sex hormones. Mail it back in the prepaid package.

Results Review
Results come back in about 1 to 2 weeks. We’ll walk through every hormone, every ratio, and your cortisol curve together. You’ll understand exactly what’s going on and why you feel the way you do.
4
Treatment Plan
Based on your results, we’ll create a plan — which might include bioidentical hormone therapy, adrenal support, IV nutrient therapy, diet and lifestyle changes, stress management, or supplements. Patients focused on longevity and anti-aging benefit from regular hormone monitoring as part of their wellness plan. We retest regularly to make sure things are moving in the right direction.
Is salivary testing really more accurate than blood testing for hormones?
For measuring active hormone levels — yes. Blood measures total hormones (active + inactive), and over 99% of what’s in your blood is inactive. Saliva only captures the free, active hormones that your cells can actually use. For setting and adjusting BHRT dosing, it’s far more reliable than blood work alone.
When during my cycle should I test?
For cycling women, we usually collect on days 19-22 of your cycle (the luteal phase) to capture peak progesterone. If you’re postmenopausal or on continuous hormone therapy, timing is more flexible. We’ll give you exact instructions based on your situation.
Can men get salivary hormone testing?
Absolutely. We test testosterone, DHEA, estrogen, and cortisol in men. It’s especially useful for men dealing with fatigue, low drive, belly fat, brain fog, and mood changes — all signs of andropause (male hormone decline).
Does insurance cover salivary hormone testing?
Many insurance companies do cover salivary testing. Coverage depends on your plan. We’ll help you check your benefits before testing so you know what to expect. Many of our patients find it very affordable even without coverage.
How often should I retest?
If you’re on hormone therapy, we retest about 4-6 weeks after starting or changing a dose. Once your levels stabilize, every 3 to 6 months is usually enough. For cortisol and adrenal issues, we may retest sooner to track your stress response.
Do I need salivary testing if I’m already getting the DUTCH test?
They serve different purposes. The DUTCH test measures hormone metabolites — how your body breaks down and processes hormones. Salivary testing measures your active hormone levels right now. We often use both together. DUTCH tells us how your body handles hormones. Saliva tells us how much active hormone you have. Both pieces matter.
Salivary hormone testing shows you the truth about your active hormone levels — not just the total. We see patients from Sandy Springs, Dunwoody, Buckhead, Brookhaven, and all over Atlanta. Get in touch — we’re happy to answer your questions.
