InstalabComprehensive Plus Hormone Profile
Should you take a Comprehensive Plus Hormone Profile test?
This test is most useful if any of these apply to you.
10 Biomarkers Included
- Cortisol AM30Captured about 30 minutes after waking, this is meant to be your daily cortisol peak and anchors the top of your stress-hormone curve.A weak morning peak can signal a blunted or shifted daily rhythm rather than simple tiredness.
- Cortisol NoonA midday reading that shows how steeply cortisol is falling from its morning peak toward evening.Midday levels help reveal whether your daily decline is steep and regulated or flat.
- Cortisol EveningAn early-evening reading that tracks the downward slope of the curve before the nighttime low.An elevated evening value suggests the daily fall-off is flattening out.
- Cortisol NightThe late-night low point, when cortisol should bottom out; this reading carries much of the curve's health signal.A high nighttime value is the pattern most consistently tied to poorer long-term health.
- DHEA-SThe adrenal gland's most abundant steroid (DHEA-S), a stable precursor your body turns into both androgens and estrogens.Low levels can reflect reduced adrenal reserve, while high levels can point to adrenal androgen excess.
- EstradiolThe most active estrogen, reflecting ovarian output in women and conversion from testosterone in men.Very low estradiol in men and low estradiol in women both carry health implications.
- EstriolThe weakest estrogen, most relevant in pregnancy but included to round out the estrogen picture.Outside pregnancy, estriol adds context to overall estrogen balance rather than standing alone.
- EstroneA longer-lasting estrogen that becomes the dominant one after menopause, made largely in fat tissue.Elevated estrone can reflect greater conversion of hormones in body fat.
- ProgesteroneReflects ovulation and the second half of the cycle in women and serves as an upstream precursor to other steroids.Low progesterone after mid-cycle can indicate that ovulation did not occur that month.
- TestosteroneThe main androgen, tracking gonadal and adrenal androgen output in both men and women.High values in women suggest androgen excess, while low values in men suggest reduced gonadal output.
About Comprehensive Plus Hormone Profile
Your body runs two big hormone systems on the same raw material, and they constantly influence each other. This profile reads both at once: the daily stress rhythm from your adrenal glands and the sex hormones from your ovaries or testes. Seen together, they show patterns that a single hormone drawn at a single moment cannot.
The value is in the relationships. A cortisol curve that never settles at night, an adrenal reserve hormone that has drifted low, or estrogen that runs high relative to progesterone each means more when read against the others.
What This Panel Reveals
Cortisol is your main daytime stress and wake-up hormone. It is meant to rise to a peak about half an hour after you wake, then fall to a low point late at night. Measuring it four times across one day (morning, noon, evening, and night) shows the shape of that decline, which a single blood test cannot capture. A flat curve, or one that stays high at night, is the pattern most consistently linked to poorer health.
An adrenal hormone called DHEA-S sits at a crossroads. Your adrenal glands make it in large amounts, and your body converts it into both male-type and female-type hormones in tissues throughout the body. It changes little across the day, so it reflects your longer-term adrenal output rather than one moment in time. Read next to cortisol, it helps separate steady adrenal reserve from short-term stress.
The sex-hormone side covers three estrogens (estradiol, estrone, and estriol), progesterone, and testosterone. These share a single production line that begins with cholesterol, so they read best as a pathway rather than as separate numbers. Testosterone tracks androgen output, progesterone reflects ovulation and the second half of the menstrual cycle, and the estrogens describe estrogen production and how much is converted in tissues such as fat.
Because the stress axis and the reproductive axis draw on shared building blocks and signal to each other, sustained stress can suppress reproductive hormones. Reading cortisol, DHEA-S, and the sex hormones together can show that coupling, or its breakdown, in a way that no single test reveals.
How to Read Your Results Together
This panel is about combinations. A few patterns recur often enough to be worth recognizing in your own results.
| Pattern | What It Suggests |
|---|---|
| Flat cortisol curve with a high late-night value, plus low DHEA-S | Long-term strain on the stress system. Worth repeating and reviewing sleep, illness, and stress load before acting. |
| Normal or high cortisol with low estrogen, progesterone, or testosterone | Points toward stress-related suppression of the reproductive axis rather than primary ovarian or testicular failure. |
| High DHEA-S with high testosterone in a woman | Suggests androgen excess from the adrenals or ovaries, a pattern seen in polycystic ovary syndrome (PCOS). |
| Low testosterone or very low estradiol with preserved DHEA-S | Suggests the gonads, not the adrenal precursor supply, are the weaker link. |
When androgen excess is the question, total testosterone is the more reliable first marker, correctly flagging about 74% of affected women and reading normal in about 86% of women without excess, while DHEA-S is less specific at about 67%. A high DHEA-S with normal testosterone is a softer signal than a high testosterone. For the estrogens, a profile of high estrogen relative to progesterone is best read as a ratio within a specific life stage, not as a standalone diagnosis, and the cortisol curve is read as a shape because it has no clean numeric cutoffs.
Why These Patterns Matter
The way cortisol falls across the day tracks with hard outcomes. In a large workplace cohort, each step toward a flatter daily decline was linked to a 30% higher risk of death from any cause (hazard ratio 1.30) and an 87% higher risk of death from heart disease (hazard ratio 1.87), while the morning value alone showed no such link. A review of 80 studies found flatter curves tied to worse health overall, most strongly for inflammation.
The adrenal reserve hormone carries its own signal. In a large community study, each standard drop in DHEA-S was associated with a 7% higher risk of new heart failure in men (hazard ratio 1.07) and a 17% higher risk in women (hazard ratio 1.17). A pooled analysis found men with higher levels had about a 28% lower risk of death from any cause (hazard ratio 0.72). Higher is not simply better, though: very high DHEA-S has also been linked to increased mortality, so the relationship appears U-shaped rather than a straight line.
Sex-hormone extremes matter too, though this evidence is observational. In a pooled analysis of men, testosterone below 7.4 nmol/L (213 ng/dL) was linked to higher death from any cause, and below 5.3 nmol/L (153 ng/dL) to higher death from heart disease, with very low estradiol adding risk. These findings describe populations, not guarantees for any one person.
What to Do with Your Results
Treat a single abnormal result as a reason to look closer, not a diagnosis. Cortisol readings swing from day to day, so a flat or high-at-night curve is worth repeating before you act on it. Sex hormones should be drawn at the right point in the menstrual cycle for anyone who still cycles, since the same value means different things across the month.
Which specialist to see depends on the pattern. Androgen excess, irregular cycles, or fertility questions point toward a gynecologist or reproductive endocrinologist, while signs of true adrenal disease, such as rapid changes in body hair, weight, or blood pressure, point toward an endocrinologist. Rapid development of male features in a woman, or new breast tissue in a man, warrants prompt evaluation, because a large excess of sex hormones or their precursors can signal an adrenal tumor.
A few companion tests sharpen the picture: a carrier protein called SHBG shows how much of your testosterone and estrogen is actually free and active, the pituitary signals LH and FSH help locate a problem in the brain versus the gonads, and thyroid testing rules out a thyroid cause of overlapping symptoms. For prevention, retest at least once a year, and sooner after any deliberate change, so you can see direction rather than a single snapshot.
When Results Can Be Misleading
Several things shift this whole panel at once. Hormonal birth control and hormone therapy change sex-hormone readings and can make androgen testing unreliable, so results are cleaner after stopping for at least three months where that is safe. Poor sleep, shift work, or acute illness can flatten the cortisol curve without any underlying disease. Menstrual-cycle timing moves estrogen and progesterone dramatically, and biotin supplements plus differences between lab methods can shift individual numbers, which is why the pattern matters more than any single value.
