Testosterone, Total

Total Testosterone

Total testosterone measures all testosterone in your blood: free, albumin-bound, and SHBG-bound. It is the primary test for evaluating male hypogonadism and androgen excess in women.

About This Test

What the Testosterone, Total test tells you

Total testosterone measures every molecule of the hormone in the blood sample, whether it is circulating free or held by a carrier protein. In men almost all of it is produced by the Leydig cells of the testes under instruction from the pituitary; women produce a much smaller amount in the ovaries and adrenal glands, where it still matters for libido, muscle and bone. Testosterone drives the development of male characteristics at puberty and, in adult life, supports muscle mass, bone density, red cell production, sexual function and mood. It is the standard first test when androgen deficiency or androgen excess is being considered.

The measurement carries two practical caveats that shape how it is used. The first is timing: testosterone follows a daily rhythm, sitting at its highest in the earlier hours and easing off through the day, so the sample is conventionally taken in the morning and repeat tests are booked at a similar time. The second is that the total includes hormone that is bound and therefore not immediately available. Most of it is attached to SHBG and to albumin, and when SHBG is unusually high or low the total can drift away from what a person actually has available to use. That is why SHBG is frequently measured alongside it and a free testosterone calculated from the two.

Because a single value can be pulled down by a poor night's sleep, an acute illness or the wrong time of day, a low result is not treated as final. Standard practice is to repeat it on a separate morning before anything is concluded, and to look at LH and FSH at the same time to establish whether any deficiency arises in the testes themselves or in the pituitary that signals them. In women, a raised total testosterone is usually assessed as part of an investigation of irregular periods, excess hair growth or acne, where the degree of elevation and how quickly symptoms appeared both guide what happens next.

Why Get Tested?

Initial test for male hypogonadism symptoms, evaluation of PCOS in women, monitoring testosterone replacement therapy, and assessing delayed puberty.

  • Investigating androgen deficiency

    It is the standard first test in a man with fatigue, low libido, erectile difficulty or loss of muscle and bone, and the starting point for any further assessment.

  • Assessing androgen excess

    In women with irregular periods, excess hair growth or acne, total testosterone helps judge whether androgen levels are contributing and how far.

  • Explaining the source of a problem

    Read with LH and FSH, it separates a testicular cause from a pituitary or hypothalamic one, which changes what is done next.

  • Monitoring replacement therapy

    For men on testosterone treatment, the total level guides dose adjustment and is checked at intervals your doctor specifies.

When This Test Is Ordered

Reasons your doctor may request the Testosterone, Total test

Your doctor may order this test for any of the reasons below. Some are routine checks, others follow specific symptoms or an earlier result.

  • Symptoms in men & women

    • Fatigue, low libido, erectile difficulty or loss of muscle mass and strength in a man.
    • Irregular or absent periods, excess hair growth, or persistent acne in a woman.
    • Unexplained loss of bone density in a man.

  • Male infertility

    • Assessment of male infertility alongside semen analysis and pituitary hormones.

  • Puberty & replacement therapy

    • Delayed puberty in a boy, or signs of early virilisation in a child.
    • Monitoring of testosterone replacement therapy.

Book a morning appointment.

Testosterone is naturally highest in the earlier part of the day and drifts down as the day goes on, so a morning sample is the convention and keeps repeat results comparable: aim for a similar time each visit. Fasting is not essential, though many people attend before breakfast because other tests are booked at the same time; follow the instructions given for those.

Postpone the test if you are unwell, sleeping badly or recovering from a demanding period of training or illness, since all of these lower the result temporarily and can be misleading. If you use a testosterone gel or patch, tell the team, keep it away from the arm being sampled and wash your hands thoroughly, as residue can produce a falsely high reading.

Bring a list of medications, particularly opioid painkillers, steroid tablets and any hormone therapy. A low result will usually be repeated before it is acted on.

Understanding Your Results

The Normal band, 250 to 916 ng/dL, reflects a typical adult male range; women produce much less, so a woman's result is judged against female expectations. A result in the Low band, 0 to 249 ng/dL, may point to the testes or to the pituitary that signals them, but it is also pulled down by a sample taken later in the day, poor sleep, illness, excess weight, opioid or steroid treatment, or a low SHBG. A result in the High band, 917 to 1500 ng/dL, is seen with testosterone or steroid use, with polycystic ovary syndrome in women, with adrenal causes, and sometimes only because SHBG is high. Testosterone peaks in the morning, so samples are taken then and repeats booked at a similar time. A single low result is normally repeated on another morning, usually with LH, FSH and SHBG, before your doctor reads the set with your symptoms and history.

Ranges are a guide: your physician interprets your result alongside your symptoms and history.

Reading a High or Low Result

  • What a higher result can point to

    • Polycystic ovary syndrome in women, the commonest reason for a modestly raised result.
    • Testosterone therapy, anabolic steroid use, or supplements containing androgen precursors.
    • Congenital adrenal hyperplasia and other adrenal disorders producing excess androgen.
    • An androgen-secreting tumour of the ovary, testis or adrenal gland, uncommon but important to exclude: particularly when symptoms appeared quickly.
    • A high SHBG, which raises the total while the freely available fraction may not be raised at all.
    • Contamination from a topical testosterone gel applied before the blood was taken.

  • What a lower result can point to

    • Testicular failure from a genetic cause such as Klinefelter syndrome, or from injury, infection, or cancer treatment.
    • A pituitary or hypothalamic problem interrupting the signal to the testes, including a tumour, surgery or raised prolactin.
    • Excess body weight, insulin resistance and type 2 diabetes, which lower testosterone through several mechanisms.
    • Long-term opioid painkillers, glucocorticoid treatment, or hormone-suppressing therapy given for prostate cancer.
    • Serious or prolonged illness, poor sleep and heavy overtraining, all of which suppress the axis temporarily.
    • A low SHBG, which can pull the total down while the freely available fraction is better preserved.

These are possibilities, not diagnoses. A single value outside the reference range is interpreted alongside your symptoms, history and other tests: your doctor decides what it means for you.

Limitations & Safety

What this test cannot tell you

  • Testosterone varies through the day and from day to day, so a single result (particularly a low one) is normally repeated on a separate morning before it is acted on.
  • The total includes bound hormone, so when SHBG is unusually high or low it can misrepresent how much is actually available; SHBG or a free testosterone is needed to resolve this.
  • Assays are less reliable at the low concentrations found in women and children, so results are best compared within one laboratory.
  • Acute illness, sleep deprivation and significant stress temporarily lower testosterone, and testing during these is likely to mislead.

Risks of the blood draw

  • Mild bruising or brief soreness where the needle went in.
  • Occasional lightheadedness, which settles after a few minutes of rest.
  • Bleeding or infection at the site, which is rare with sterile single-use equipment.
Key Points
  • 1Total testosterone counts both the bound and the free hormone, which is why it can differ from the free measurement.
  • 2The sample is conventionally taken in the morning, when testosterone is naturally highest.
  • 3A single low result is normally repeated on another morning before any conclusion is drawn.
  • 4LH and FSH are usually measured with it to show whether the testes or the pituitary is responsible.
  • 5Where SHBG is expected to be unusual, a free or calculated free testosterone gives a truer picture.

Testosterone follows a daily rhythm, running highest in the earlier hours and falling away later. A sample taken in the afternoon can read lower simply because of the time. Taking it in the morning, and at a similar time on each occasion, makes results comparable and reduces unnecessary repeat testing.
