Why take this test?
This test profile has been designed for men taking testosterone therapy who want to monitor their male and female hormones. This test includes total testosterone as well as a calculation of the amount of free or unbound testosterone that is available to your tissues. Most testosterone in the body is bound to proteins (sex hormone binding globulin and albumin) and is unavailable to your cells. By measuring your total testosterone and your levels of SHBG and albumin, the laboratory can calculate your level of free testosterone. Low free testosterone can cause symptoms such as low libido, lack of muscle mass, and low mood.
It is also important to check the levels of female hormones in the blood, especially if you are experiencing symptoms which are associated with high oestradiol (including growth of breast tissue and low libido).
Monitoring your hormone levels allows you and your practitioner to optimise your dose of testosterone replacement.
Please ensure your sample is collected in the morning. If you are tracking your results over time then it is vital that you always have your blood taken at the same time.
Extended upper limit. Many testosterone tests will not measure testosterone levels above 52 nmol/L, our test will measure values up to 520 nmol/L. This is especially useful for men who are taking testosterone replacement therapy (TRT) or anabolic steroids and who expect to have supranormal levels of testosterone. Please note, if your reading is above 520nmol/L the lab will not be able to calculate a free testosterone or free androgen index value. If this is the case, you will not be entitled to a refund.
We send you an easy-to-use kit to collect your blood sample.
Post your sample to our lab in the prepaid envelope provided.

A PSA (prostate specific antigen) test is included in this health screen. PSA is a protein which can be elevated in prostate cancer. However, like all tumour marker tests, the PSA has limitations as it can be raised in benign conditions and even after recent ejaculation or bike riding. It can also be normal when cancer is present. The PSA test is accepted as a screening test for cancer., especially in men over the age of 50. An elevated result will require further investigation, some of which may be invasive e.g. biopsy, and may still lead to a negative result. However, a positive test gives you the chance to detect cancer early when treatment is more likely to be successful. Please make sure you think carefully about the risks and benefits of a PSA test before taking this test.

Albumin is made mainly in the liver and helps to keep the blood from leaking out of blood vessels. It also helps carry some medicines and other substances through the blood and is important for tissue growth and healing.
Low albumin levels can indicate liver disease and can also be a marker for chronic ill-health, malnutrition and inflammation. It can also occur in kidney conditions such as nephrotic syndrome and diabetes.
Raised levels are usually caused by dehydration.
Testosterone is a male sex hormone which is produced in the testicles of men and, in much smaller amounts, in the ovaries of women. It is responsible for bone and muscle strength, as well as mood, energy and sexual function.
Testosterone levels decline with age and it is unusual to find naturally elevated levels in men. Low testosterone is more common than raised testosterone in the absence of supplementation.
In women, raised testosterone can result in male characteristics such as body hair, greater bulk, a deeper voice and acne - all symptoms of polycystic ovaries, a condition in which elevated testosterone is commonly seen.
Most testosterone circulating in the blood is bound to proteins, in particular SHBG and albumin; only 2-3 % of testosterone is free and available to cells. This test uses an algorithm to calculate the level of free or unbound testosterone in relation to total testosterone, SHBG and albumin.
A low level in a male could lead to symptoms such as low libido, erectile dysfunction, depression and difficulty gaining muscle mass.
In women an elevated level could indicate polycystic ovary syndrome.
Oestradiol is a female steroid hormone which is produced in the ovaries of women and to a much lesser extent in the testes of men. It is responsible for the female reproductive system as well as the growth of breast tissue and bone thickness. Oestradiol levels decline with age, culminating in the menopause when the ovaries stop producing eggs.
Raised oestradiol in women can cause acne, constipation, loss of sex drive and depression as well as raising the risk of uterine and breast cancer.
Oestradiol can also be raised in men due to excess fat (which produces oestradiol) or in relation to testosterone levels which have declined with age. Raised oestradiol in men can cause the growth of breast tissue, the loss of libido and infertility.
Low levels of oestradiol in women can lead to osteoporosis, problems with the menstrual cycle and fertility as well as fatigue and depression.
Most of the sex hormones - testosterone, oestrogen and dihydrotestosterone (DHT) - found in your blood are bound to Sex Hormone Binding Globulin (SHBG) which means that they are unavailable to your cells. Measuring the level of SHBG in your blood gives important information about your levels of "free" or unbound hormones which are biologically active and available for use.
Elevated SHBG indicates that there is less testosterone or oestrogen available for use whereas low levels can mean an excess of available hormones.
Prolactin is a hormone which is produced in the pituitary gland and plays a role in reproductive health. Its primary purpose is to stimulate milk production after childbirth, and in pregnant and breastfeeding women prolactin levels can soar.
Raised levels in a woman who isn't pregnant or breastfeeding can signal fertility problems as well as irregular periods.
Raised levels in men can cause reduced sex drive, lack of energy, erectile disfunction and fertility problems.
