About the HRT blood test
HRT – Hormone Replacement Therapy is the general term for the replacement of hormone which is currently low or deficient. Our test checks a number of key hormones that may undergo this type of treatment.

Biomarker information for HRT blood test
FSH is a hormone produced by the pituitary gland in the brain. This hormone is essential for producing eggs in women and producing sperm in men. In women, FSH levels peak at ovulation and can increase in menopause.
Oestradiol is the primary female sex hormone, but it is also an essential hormone for men. It is a type of hormone called an oestrogen that supports a healthy reproductive system and healthy breast tissue and bones.
Thyroid stimulating hormone (TSH) is produced in the pituitary gland in order to regulate the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3) by the thyroid gland. If thyroid hormones in the blood are low, then more TSH is produced to stimulate the thyroid gland to produce more of them. If thyroid hormone levels are high, then the pituitary produces less TSH to slow the production of thyroid hormones.
If TSH is too high or too low, it normally signifies that there is a problem with the thyroid gland which is causing it to under or over produce thyroid hormones. Sometimes a disorder of the pituitary gland can also cause abnormal TSH levels.
Thyroxine (T4) is one of two hormones produced by the thyroid gland. It works to speed up the rate of your metabolism. Most T4 is bound to carrier proteins in the blood – it is only the free, or unbound, T4 that is active in the body. Free T4 is the less active of the two main thyroid hormones. To have an impact on your cells it needs to convert to the more active T3 when your body needs it.
The random blood glucose test measures the level of sugar in your blood and is an indicator of how well your body is metabolising sugars to store in your cells. It is most useful when analysed in conjunction with other sugar markers, such as HbA1c.
Cholesterol is an essential fat (lipid) in the body. It has some important functions, including building cell membranes and producing a number of essential hormones such as testosterone and oestradiol. There are a number of different types of cholesterol, but the two main components of total cholesterol are HDL (high density lipoprotein) -“Good” and LDL (low density lipoprotein)- “Bad”.
The total cholesterol result on its own only shows the total amount of both of these components and so even if you have a good amount of total cholesterol, you may have a low amount of good cholesterol and high amount of bad cholesterol therefore its important to review each of these results to understand your cardiovascular health and risks of cardiovascular disease.
HDL cholesterol (high-density lipoprotein) is a molecule in the body which removes cholesterol from the bloodstream and transports it to the liver where it is broken down and removed from the body in bile. HDL cholesterol is commonly known as ‘good cholesterol’.
LDL cholesterol (low-density lipoprotein) is a molecule made of lipids and proteins which transports cholesterol, triglycerides and other fats to various tissues throughout the body. Too much LDL cholesterol, commonly called ‘bad cholesterol’, can cause fatty deposits to accumulate inside artery walls, potentially leading to atherosclerosis and heart disease.
Cholesterol in your body is generally broken down into 2 main components; HDL and LDL. However there are other types of cholesterol such as VLDL (very low-density lipoproteins) and other lipoproteins which are thought to be even more harmful than LDL cholesterol. Non-HDL cholesterol is calculated by subtracting your HDL cholesterol value from your total cholesterol. It therefore includes all the potentially harmful cholesterol in your blood including LDL. As such, it is considered to be a better marker for cardiovascular risk than total cholesterol and LDL cholesterol.
Triglycerides are a type of fat (lipid) that circulate in the blood. After you eat, your body converts excess calories (whether from fat or carbohydrates) into triglycerides which are then transported to cells to be stored as fat. Your body then releases triglycerides when required for energy.
What does the HRT blood test involve?
This blood test is just like a standard blood test.
You will be asked to uncover you left or right arm and suitable vein is found. A tourniquet will be placed and tightened around your upper arm allowing the veins to swell and a needle will be placed into your vein. A small quantity of blood is then drawn into tubes. Once the procedure is complete a small plaster will be placed onto the site which can be removed after a few hours.
How do I prepare
- The blood test requires access to the area of interest, therefore, it is recommended to wear loose clothing to facilitate this process.
- No specific preparation is required for this scan.
- We will require details of your GP / Health Care Professional, which may be requested before or at the time of the scan.
- Blood results require interpretation. All results should be interpreted by your regular health care professional / GP.
