What’s included in this test

Thyroid health
Free T4
Free T4 gives insight into the level of unbound thyroxine hormone. It’s key for diagnosing thyroid conditions when TSH alone is inconclusive.
TSH
TSH controls the thyroid gland’s hormone production. It’s the most common marker for identifying thyroid dysfunction, such as hypothyroidism.
Free T3
Free T3 is the active form of triiodothyronine, a thyroid hormone. It’s useful in identifying hyperthyroidism or ineffective thyroid conversion.
Hormone health
Follicle stimulating hormone level (FSH)
FSH regulates reproductive processes and is essential for fertility. It’s used to assess ovarian reserve in women or testicular function in men.
Luteinising hormone (LH)
Luteinising Hormone (LH) plays a critical role in ovulation and testosterone production. It's commonly tested in fertility and hormonal evaluations.
Oestradiol
Oestradiol is the primary form of estrogen in women. This test is essential in fertility assessments, menstrual irregularities, or hormone replacement therapy.
Testosterone Free
Free Testosterone provides an estimate of biologically active testosterone, useful in diagnosing hormonal imbalances not reflected in total testosterone alone.
Testosterone
Testosterone testing measures total testosterone levels to assess libido, mood, and metabolic function in both men and women.
Sex hormone binding globulin level (SHBG)
SHBG regulates the availability of sex hormones like testosterone and oestradiol. Abnormal levels can indicate hormonal imbalance or liver dysfunction.
Prolactin
Prolactin is a hormone primarily involved in lactation but also impacts fertility and menstrual cycles. High levels can suggest pituitary issues.
Liver health
Albumin
Albumin is a major protein in the blood, essential for maintaining fluid balance and transporting nutrients. Low levels can signal liver or kidney disease.

FAQs

What are female hormones?
Female hormones are vital not only for reproductive health but also for overall well-being, influencing energy levels, mood, and metabolism. Oestradiol (E2), the primary form of oestrogen, is produced in the ovaries and plays a central role in the menstrual cycle and fertility. Other key hormones include follicle-stimulating hormone (FSH), luteinising hormone (LH), and progesterone. Together, these hormones help regulate the menstrual cycle and support reproductive function. Testosterone, often thought of as a male hormone, is also important for women. It is used by the body to produce oestrogen and plays a role in maintaining bone and muscle strength, mood, energy levels, and libido. Hormone levels naturally fluctuate throughout the menstrual cycle and shift with age. As women approach perimenopause and menopause, oestrogen and progesterone levels typically decline, while FSH and LH levels increase in response to these changes.
What is prolactin?
Prolactin is a hormone produced by the pituitary gland that supports reproductive health. It’s best known for its role in stimulating milk production during pregnancy and breastfeeding, when levels naturally rise. Prolactin also influences the menstrual cycle, and elevated levels can affect the balance of other key reproductive hormones, such as follicle stimulating hormone, luteinising hormone, oestrogen and testosterone.
What are the most important hormones to test for fertility?
Several hormones are key to fertility, as they help regulate the menstrual cycle and support ovulation. These include follicle stimulating hormone, luteinising hormone and oestradiol to gain further insight into reproductive health, it can also be helpful to test levels of testosterone, progesterone, prolactin, DHEA-S, and AMH. Thyroid hormones also play an important role, as imbalances can affect cycle regularity and ovulation.
When should I take a female hormone test?
Testing female hormone levels is best between days two and five of your menstrual cycle, with day three being ideal. At this stage, levels of luteinising hormone (LH), follicle-stimulating hormone (FSH), and oestradiol are typically at their lowest and most stable. If your periods are irregular, aim to take the test on day three of your next cycle. If that is not possible, or if you do not have periods, you can take the test on any day, but please let us know the date your sample was collected, so we can interpret your results accurately. For the most reliable results, we recommend taking your sample in the morning, as hormone levels can fluctuate throughout the day.
Why should I test my thyroid?
If you're experiencing symptoms like unexplained changes in weight, energy levels, mood, skin, or hair, your thyroid could be a contributing factor. The thyroid plays a crucial role in regulating your metabolism, body temperature, and energy production, so even slight imbalances can affect how you feel day to day. A thyroid blood test can help determine whether your thyroid is functioning properly by measuring key hormones such as TSH, FT4, and FT3. Identifying an underactive (hypothyroidism) or overactive (hyperthyroidism) thyroid early can make a significant difference in managing your symptoms and improving your overall well-being.
What is thyroid disease and who is at risk?
It is estimated that around 1 in 20 people may have a thyroid disorder. Several conditions can impact the normal function of the thyroid, including an underactive thyroid (hypothyroidism), an overactive thyroid (hyperthyroidism), autoimmune thyroid disease, thyroid swelling (goitre), nodules, or thyroid cancer. While anyone can develop a thyroid disorder, certain factors increase the risk. These include being female, being over the age of 50, or having a family history of thyroid problems.
Why is testosterone included in my female hormone test?
Although often considered a male hormone, testosterone also plays an important role in female health. As women approach menopause, testosterone levels, along with oestrogen tend to decline, which can contribute to symptoms such as low mood, fatigue, and a reduced sex drive. Conversely, elevated testosterone levels in women may be a sign of polycystic ovary syndrome (PCOS), a common condition that can disrupt ovulation and affect fertility.
