Hormones influence energy, mood, libido, weight and sleep. Our clinician-reviewed panels help build a clearer picture of what may be contributing to your symptoms.
Onsite laboratory: samples are processed in the same building within minutes of collection, never in external transit. Faster turnaround, no sample degradation, results you can trust.
Hormone testing panels
All panels include clinical review by a GMC-registered doctor. Same-day appointments at 134 Harley Street; turnaround varies by panel.
MOST POPULAR
The Hormone Specialist
Our most popular hormone panel. A focused assessment of the hormonal axes that drive energy, mood, libido, hair, and body composition.
DHT & androgen panel
Oestrogen (Oestradiol)
Thyroid function
Zinc
CRP
⏱ Most results within 4 hours of your appointment. DHT, oestradiol and the rest of the androgen panel returned within 24 hours. SHBG can take up to 48 hours.
Women
Female Hormone Panel
Focused female hormonal axis panel covering FSH, LH, oestradiol, SHBG, total testosterone and free T4. The standard private screen for cycle irregularities, perimenopause investigation, PMOS (formerly known as PCOS) work-up, or any gynaecology-led hormone enquiry. Fasting preferred and morning appointment recommended for the cleanest thyroid reading. Tell us at booking if you are using hormonal contraception.
FSH (Follicle Stimulating Hormone)
LH (Luteinising Hormone)
Oestradiol
SHBG (Sex Hormone Binding Globulin)
Total testosterone
Free T4
⏱ FSH, LH and free T4 returned within 4 hours of your appointment. Oestradiol and total testosterone returned within 24 hours. SHBG can take up to 48 hours (clinician then interprets the result before release).
All
Adrenal Function Panel
Focused adrenal panel measuring morning cortisol and DHEA-sulfate. Strict timing matters: bloods must be drawn between 8 and 9 AM (10 AM is the absolute latest), after an 8 to 12 hour overnight fast (do not fast longer than 12 hours), to capture the natural cortisol peak. The standard first-line check of how your adrenal glands are working, used to investigate unexplained fatigue, stubborn hair shedding, or androgen-driven hair loss in women.
Cortisol (morning serum)
DHEA-sulfate (DHEAS)
Total testosterone
SHBG
⏱ Cortisol returned within 4 hours of your appointment. DHEAS and total testosterone returned within 24 hours. SHBG can take up to 48 hours (clinician then interprets the result before release).
Men
Testosterone Panel
A focused testosterone panel covering total testosterone, free testosterone and DHT. Drawn 7 to 11 AM after an overnight fast as per BSSM testosterone deficiency guidance, and clinically reviewed.
DHT (dihydrotestosterone)
Total testosterone
Free testosterone
⏱ Total testosterone and DHT returned within 24 hours of your appointment. Free testosterone is reported as a calculated value from SHBG plus albumin, so SHBG can take up to 48 hours before the full result is released by the clinician.
Same-day appointments usually available
Direct-access hormone testing on Harley Street. No GP referral required.
Hormones do not announce themselves loudly. The signs that something is off are usually a slow drift across energy, mood, sleep, body composition, libido, and sometimes hair. Any cluster of the following is worth investigating.
Persistent fatigue with normal blood pressure
Particularly if the fatigue is worst in the afternoon or you wake up unrefreshed. Thyroid function, iron studies and, where clinically indicated, the cortisol axis are useful first checks.
Low libido in men or women
Often dismissed as stress or ageing but commonly traceable to testosterone, oestradiol, prolactin, or thyroid status. All measurable on a single morning draw.
Scalp hair thinning with no clear cause
DHT in men, the androgen panel and oestradiol balance in women, plus thyroid antibodies. The Advanced Hair & Hormone Check covers all of these together.
Irregular or skipped periods
FSH, LH, oestradiol, and prolactin tell the story. Particularly relevant in perimenopause investigation and PCOS work-up. See the Female Hormone Panel.
Mood swings or low mood not linked to events
Thyroid dysfunction, low testosterone in men and perimenopausal oestrogen drops in women are measurable contributors that are worth ruling in or out. Often manageable once identified.
Central weight gain despite no change in diet
Insulin resistance, cortisol excess, and low testosterone all drive this pattern. Worth catching early before it becomes harder to reverse.
What each hormone we test tells us
A hormone level is only useful in context. Our reports interpret each marker against your symptoms, age, sex, and the rest of your panel. These are the markers most commonly worth measuring.
TOT
Total and free testosterone
Total testosterone is what most clinicians look at first. Free testosterone, calculated from SHBG, is the biologically active fraction and often the more useful number, especially in patients with insulin resistance or hyperthyroidism where SHBG shifts.
DHT
DHT (dihydrotestosterone)
The active downstream androgen and the mechanistic driver of pattern hair loss at the follicle. Serum DHT is provided for context, though it correlates poorly with severity on its own. Useful when reviewing response to finasteride alongside clinical assessment.
OES
Oestradiol
The principal oestrogen. Useful as supporting context during the perimenopausal transition (NICE NG23 diagnoses perimenopause on symptoms alone in women over 45) and in men where raised oestradiol can contribute to symptoms often attributed to low testosterone.
FSH
FSH and LH
Pituitary hormones that drive the ovaries and testes. FSH rises in perimenopause and menopause. In women under 45 it is the most useful single hormone marker; NICE NG23 advises against routine FSH testing in women over 45, where perimenopause is diagnosed clinically. The LH-to-FSH ratio is a supporting indicator in PCOS work-up.
SHB
SHBG (sex hormone binding globulin)
The carrier protein for testosterone and oestradiol. Low SHBG is one of the earliest signs of insulin resistance, often years before HbA1c moves.
COR
Cortisol and DHEAS
The adrenal axis. Useful in persistent fatigue that does not fit a thyroid or iron picture, in central weight gain with mood changes, and in women investigating androgen excess where the source may be adrenal rather than ovarian.
THY
Thyroid function (TSH, free T4, free T3)
Affects metabolism, mood, energy, weight, and hair growth. A TSH on its own often misses the picture in patients with thyroid antibody positivity or central hypothyroidism.
Why private hormone testing?
NHS hormone testing follows NICE-guided referral thresholds and tends to test fewer markers per visit. Private testing offers wider panels reviewed by GMC-registered doctors, on your timeline.
