DHEA-S

DHEA-S is the storage form of DHEA, the hormone your adrenal glands make as raw material for testosterone and oestrogen. It peaks around your twenties and falls steadily after that, and because it does not move with the clock, it is the calm counterpart of cortisol from the same glands.

In short

Healthy is a DHEA-S that fits your age: where the labs overlap for a man at age 30 4.1 to 10.19 µmol/l and at age 70 1.1 to 5.4 µmol/l, for a woman at age 30 1.6 to 6.2 µmol/l and at age 70 1.7 to 2.4 µmol/l; the decline with the years is ordinary, and the first question with a deviation is which age you set it against.

  • A lower value belongs with ageing: all labs lower their band with the years, women sit lower than men at every age, and prednisone lowers the value together with cortisol; a low DHEA-S in a healthy body is no reason to top up.
  • With a high value the first question is which age you set it against; if it is genuinely raised for your age, it points to the adrenal glands as a source of male hormone, in a woman usually PCOS, and a value far above the band is investigated.
  • Unlike cortisol from the same adrenal glands, DHEA-S does not move with the hour of the day; beside cortisol it shows what is daily rhythm and what is store.
  • In a woman with excess hair growth, acne or an irregular cycle you read DHEA-S beside testosterone: DHEA-S points to the adrenal glands, testosterone to the ovaries.

What is DHEA-S?

Beside cortisol your adrenal glands make a second hormone: DHEA, a building block from which your body can make testosterone and oestrogen in the tissues. Most of it is given a sulphate group in the adrenal gland itself, which keeps it in the blood longer and makes the value stable over the day. That is DHEA-S, and in men and women it is the hormone circulating in the blood in the largest amount. In women it is the main source of testosterone after the menopause; in men it delivers a small part beside the testicles. Production begins around age seven, peaks between the twenties and thirties and falls steadily after that, to about a fifth of the peak around seventy. That decline is the subject of most questions about DHEA-S, and it is ordinary: all labs lower their band with the years, and women sit lower than men at every age. A value that comes out above the band in a man at age 70 falls in the middle of the normal range in a man at age 30. Unlike cortisol, DHEA-S does not move with the hour, so the time of the draw matters little; prednisone and other steroids do lower it, because they shut down the brain's order to the adrenal gland. Your report shows DHEA-S in µmol/l, and the band belongs to your age and sex. Where the bands overlap it runs for a man at age 30 from 4.1 to 10.19 µmol/l, at age 50 from 1.9 to 8.4 µmol/l and at age 70 from 1.1 to 5.4 µmol/l; for a woman at age 30 from 1.6 to 6.2 µmol/l, at age 50 from 0.95 to 4.6 µmol/l and at age 70 from 1.7 to 2.4 µmol/l.

Why is DHEA-S relevant?

DHEA-S is the value that says where excess male hormone in a woman comes from. With excess hair growth, acne, an irregular cycle or hair loss on the head there are two sources: the ovaries, which mainly make testosterone, and the adrenal glands, which mainly make DHEA-S. A high DHEA-S points to the adrenal glands. In PCOS it is slightly raised in one in three women; a value far above the band, more than double, is rare and points to an adrenal gland making too much on its own, and that is investigated. The second reason is the distinction from cortisol. Both come from the same adrenal glands, but cortisol follows the clock and DHEA-S does not. Anyone who sees a deviating cortisol can read from DHEA-S whether the adrenal gland as a whole is involved: in Addison's both are low, with a course of prednisone too, and with a disturbed daily rhythm only cortisol is off. That makes DHEA-S the calm counterpart. The honest limitation is the decline with the years, which many people read as a deficiency. A lower DHEA-S with ageing goes with less muscle strength, bone density and wellbeing, but topping up with DHEA tablets has not reversed that in research in healthy older people, and in women it gives acne, oily skin and excess hair growth. It is a mirror of age, not a lever.

DHEA-S reference ranges

What counts beside the number:

  • Your age and sex, because the band shifts every decade and the same value is normal in someone of twenty and high in someone of seventy
  • Cortisol from the same draw, which comes from the same adrenal glands but moves with the clock
  • Whether you take prednisone, a steroid inhaler or a steroid ointment or have just stopped
  • In a woman: testosterone and oestradiol, and symptoms of excess hair growth, acne or an irregular cycle
  • Whether you take DHEA supplements, because those lift the value
  • With a value far above the band: how fast it rose, because that counts more than the height
DHEA-S reference ranges
GroupReference range
Men aged 30Where the three labs overlap at this age; around the peak of production4.1–10.19 µmol/l
Men aged 50Twenty years on, that same shared band sits more than twice as low1.9–8.4 µmol/l
Men aged 70About a fifth of the peak; an ordinary decline, not a deficiency1.1–5.4 µmol/l
Women aged 30Lower than in a man of the same age, as at every age1.6–6.2 µmol/l
Women aged 50Around the menopause; after the menopause DHEA-S becomes the main source of testosterone0.95–4.6 µmol/l
Women aged 70The narrowest row on this page, because one of the labs sets the band above sixty slightly higher1.7–2.4 µmol/l

There is no national reference value for DHEA-S, and one band for all adults would be the wrong number for almost everyone, because the value falls every decade; the rows above therefore stand at fixed ages, and the chart gives the answer for every age between 18 and 99. Always read the value against your own age and sex, and beside cortisol from the same adrenal glands.

What Dutch labs actually use

No other value in this library is cut as finely by age as DHEA-S. Certe publishes 64 bands, one per two years to 80, separately for men and women; Unilabs and Clinical Diagnostics work in decades, and Star-shl does not carry the test. All three show the same movement: at Unilabs the band for a man aged 20 to 30 runs from 7.6 to 17.4 µmol/l and for a man from 70 from 0.7 to 5.4 µmol/l, and for women that same series sits lower. Clinical Diagnostics breaks that pattern at the end: above sixty the men's ceiling rises again, to 11.0 µmol/l, and for women the floor.

Each band as the lab publishes it, retrieved in 2026, unless marked otherwise.

DHEA-S high or low: what it means

A low value is usually age, and the first question is which band you set it against. Every band falls with the years, so a value called low in someone of thirty is ordinary in someone of sixty. After that comes prednisone, also as an inhaler or ointment, which shuts down the brain's order to the adrenal gland and lowers DHEA-S together with cortisol; after stopping it recovers in weeks to months. Rare are adrenal glands that make too little, as in Addison's disease, and then cortisol is low too and there are symptoms of tiredness, nausea and low blood pressure. A low DHEA-S in a healthy body is not a finding and no reason to top up. A high value is first a question about the age you compare against, because the same value is normal in someone of twenty and high in someone of seventy. If the value is genuinely raised for your age, that points to the adrenal glands as a source of male hormone. In a woman with excess hair growth, acne or an irregular cycle a slightly raised value is usually PCOS, in which the ovaries and the adrenal glands both make slightly too much. A value far above the band, more than double the upper limit, is rare and fits an adrenal gland making too much on its own, and that is imaged. What you do about it: with a low value from age nothing, and with a low value from prednisone wait until the adrenal glands get going again after stopping. DHEA tablets lift the value but give women acne, oily skin and excess hair growth, and have shown no effect on strength or wellbeing in healthy older people. In PCOS weight, exercise and a diet with few fast sugars are the levers, because insulin resistance drives the production of male hormone, and the pill or drugs that block the hormone are the treatment for the symptoms. A value far above the band should be investigated, even without symptoms. Always read DHEA-S against your age and sex, beside cortisol, which comes from the same adrenal glands but moves with the clock, and in a woman with symptoms of male hormone beside testosterone, which says whether the ovaries are involved, and oestradiol.

How does a DHEA-S blood test work?

Referral
Not needed. You can have DHEA-S measured yourself; note your age on the request, because it belongs to the assessment.
Fasting
Not needed; the value does not move with food.
When
At any moment of the day, because unlike cortisol DHEA-S does not move with the hour. Skip DHEA supplements for a few days if you want to know your own production.
The draw
One tube of blood from a vein in your arm. Cortisol, testosterone and oestradiol come from the same draw; not every lab carries the test, so ask.
Repeating
Rarely needed. With a raised value after three months, to see whether it persists; with a low value from prednisone three months after stopping.
Where to draw
You can draw at 250+ locations near you, no referral needed. See the locations

Frequently asked questions

What is DHEA-S?

The storage form of DHEA, the hormone your adrenal glands make as a building block for testosterone and oestrogen. The adrenal gland attaches a sulphate group, which keeps it in the blood longer and makes the value stable over the day. It is the hormone circulating in the largest amount in men and women, and in women after the menopause the main source of testosterone.

What is a normal DHEA-S value?

That depends on your age and sex. Where the labs overlap the band runs for a man at age 30 from 4.1 to 10.19 µmol/l, at age 50 from 1.9 to 8.4 µmol/l and at age 70 from 1.1 to 5.4 µmol/l; for a woman at age 30 from 1.6 to 6.2 µmol/l, at age 50 from 0.95 to 4.6 µmol/l and at age 70 from 1.7 to 2.4 µmol/l. The value peaks between your twenties and thirties and falls a good deal every decade after that.

What does a raised DHEA-S mean?

First the question which age you compare against, because the same value is normal in someone of twenty and high in someone of seventy. If the value is genuinely raised for your age, that points to the adrenal glands as a source of male hormone. In a woman with excess hair growth, acne or an irregular cycle that is usually PCOS. A value far above the band, more than double the upper limit, is rare and fits an adrenal gland making too much on its own; that is investigated.

What does a low DHEA-S mean?

Usually age: all labs lower their band with the years, and a value called low in someone of thirty is ordinary in someone of sixty. Prednisone, also as an inhaler or ointment, lowers the value together with cortisol, and after stopping it recovers in weeks to months. Rare are adrenal glands that make too little, as in Addison's disease, and then cortisol is low too. A low DHEA-S in a healthy body is not a finding and no reason to top up.

Why does DHEA-S fall with the years?

Because the adrenal glands steadily wind production down after the peak between your twenties and thirties, to about a fifth around seventy. That is an ordinary ageing process and not a disease. A lower DHEA-S goes with less muscle strength, bone density and wellbeing, but topping up with DHEA tablets has not reversed that in research in healthy older people. The value is a mirror of age, not a lever.

Does a DHEA supplement help?

Not in healthy people. Tablets lift the blood value, but have shown no improvement in strength, bone density or wellbeing in older people, and in women they give acne, oily skin and excess hair growth, because the body makes testosterone from it. The only situation in which topping up has a place is adrenal glands that really fail, and that is set by a doctor.

What is the difference from cortisol?

Both come from the same adrenal glands, but cortisol follows the clock, high in the morning and low in the evening, and DHEA-S does not. That is why the time of the draw matters little for DHEA-S, and why the two side by side show what is daily rhythm and what is store: in Addison's and with prednisone both are low, with a disturbed daily rhythm only cortisol is off.

What does DHEA-S mean in PCOS?

That the adrenal glands are involved. In PCOS the ovaries make too much testosterone, and in one in three women the adrenal glands also make slightly too much DHEA-S. Excess hair growth, acne and an irregular cycle go with it. Weight, exercise and a diet with few fast sugars are the levers, because insulin resistance drives the production of male hormone; the pill or drugs that block the hormone treat the symptoms.
