What is Hormone Replacement Therapy (HRT)?
Hormone Replacement Therapy (HRT) is a treatment used to relieve symptoms of menopause by replacing hormones that decline as women age. During perimenopause and menopause, oestrogen, progesterone, and other hormones fluctuate significantly before declining, causing a wide range of symptoms that can significantly impact quality of life.
HRT typically involves taking oestrogen, and for women with a uterus, progestogen to protect the womb lining. Some women also take testosterone as part of their HRT regimen. The goal is to restore hormone levels to a range that alleviates symptoms whilst monitoring for safety.
Why blood testing matters for HRT:
Before starting HRT, blood tests help establish your baseline hormone levels and determine whether you're in perimenopause or menopause. Once on HRT, regular testing ensures your hormone levels are in the optimal therapeutic range and that your body is responding appropriately to treatment.
Biomarkers We Test
Our HRT Hormone Panel measures nine essential biomarkers that provide a complete picture of your hormonal health:
The primary oestrogen hormone in women. Crucial for bone health, cardiovascular protection, mood regulation, and reproductive function. Monitoring oestradiol levels helps ensure your HRT dosage is effective.
Prepares the uterus for pregnancy and regulates the menstrual cycle. In HRT, progesterone protects the womb lining. Low levels can cause irregular bleeding and mood symptoms.
Controls egg production in the ovaries. Elevated FSH is a key indicator of perimenopause and menopause. Helps determine your menopausal status.
Triggers ovulation and works alongside FSH. Elevated levels indicate ovarian function decline. Important for understanding your reproductive hormone status.
The milk-producing hormone. Elevated prolactin can suppress other reproductive hormones and cause symptoms like irregular periods, low libido, and mood changes.
Often thought of as a male hormone, but testosterone is vital for women too. Affects libido, energy, mood, muscle mass, and bone density. Many women benefit from testosterone as part of HRT.
The unbound, biologically active form of testosterone. More accurate than total testosterone for assessing true androgen status and determining if testosterone supplementation may help.
A protein that binds testosterone and oestrogen. High SHBG reduces free hormone available to tissues. Oral oestrogen HRT typically increases SHBG levels.
A calculated ratio showing testosterone not bound to SHBG. Provides a better indicator of androgenic activity than total testosterone alone.
Who Is This Panel For?
Women Considering HRT
Before starting hormone replacement therapy, understanding your baseline hormone levels is essential. This panel helps determine whether you're in perimenopause or menopause, and provides a starting point for personalising your HRT approach.
Women Currently on HRT
If you're already taking HRT, regular monitoring ensures your hormone levels are within the optimal therapeutic range. This helps confirm your dosage is appropriate and that your body is absorbing and utilising the hormones effectively.
Women Experiencing Perimenopause Symptoms
Symptoms like irregular periods, hot flushes, night sweats, mood changes, and sleep disturbances can begin years before menopause. This panel helps identify hormonal changes and guides decisions about treatment options.
Women Tracking Their Hormone Health
Even if you're not considering HRT, understanding your hormone levels provides valuable insight into your overall health. Hormones affect bone density, cardiovascular health, mood, energy, and cognitive function.
For premenopausal women still having periods, hormone levels fluctuate throughout the menstrual cycle. For the most accurate baseline, blood tests are typically taken on day 3-5 of your cycle (day 1 being the first day of bleeding). For postmenopausal women or those on continuous HRT, timing is less critical.
Why Test Your Hormone Levels?
Understanding your hormone levels provides crucial information for managing your health during perimenopause and beyond:
Blood test results help your healthcare provider tailor your HRT dosage to your specific needs, rather than using a one-size-fits-all approach.
Ensure your current HRT regimen is achieving therapeutic hormone levels and that your body is absorbing the hormones properly.
Discover hormone imbalances that may be causing symptoms like fatigue, low mood, low libido, or weight changes.
Regular testing allows you to monitor how your hormone levels change and how your body responds to treatment.
Oestrogen is crucial for bone density. Monitoring levels helps ensure you're protecting your bones during and after menopause.
Hormone levels affect cardiovascular health. Proper monitoring supports heart health during the menopausal transition.
