Do you suffer from erectile dysfunction? Our comprehensive blood test for erectile dysfunction examines the main causes of ED, including raised cholesterol, diabetes, and low testosterone levels.
We also test your thyroid hormones, which can have an impact on sexual function. By identifying the physical factors contributing to your ED, our test provides valuable insights to help you and your healthcare provider develop a targeted treatment plan to address your symptoms and improve your sexual health.
Book an appointment today with our partner clinics at Superdrug for a venous blood sample. Alternatively, you can choose to have one of our nurses or your own healthcare professional take your venous sample in the comfort of your own home. Results are normally available within 2 working days from receipt of your sample at our laboratory and delivered directly to you through our secure online patient portal.

Cholesterol profile
Total cholesterol
The ratio of cholesterol to HDL is determined by dividing the total cholesterol level by the HDL cholesterol level. It is used to assess the risk of cardiovascular disease because it provides a good indication of the proportion of total cholesterol that is beneficial (i.e. high-density lipoprotein HDL). Tools used to evaluate the risk of heart disease, such as QRisk, use the cholesterol/HDL ratio to determine the probability of a heart attack.
LDL cholesterol
Non-HDL Cholesterol
The breakdown of your total cholesterol comprises two primary constituents, namely HDL (good) cholesterol and LDL (bad) cholesterol. However, harmful cholesterol types in your blood extend beyond LDL and encompass VLDL (very low-density lipoproteins) and other lipoproteins that are believed to be even more detrimental than LDL cholesterol. Non-HDL cholesterol is obtained by deducting your HDL cholesterol value from the total cholesterol value. Consequently, it incorporates all the non-protective and potentially harmful cholesterol in your blood, not just LDL. Thus, it is considered a better indicator of cardiovascular risk compared to total cholesterol and LDL cholesterol. The recommended non-HDL cholesterol level is below 4 mmol/L.

Hormones
Testosterone
Prolactin
Prolactin is a hormone that is synthesized in the pituitary gland and is involved in the regulation of reproductive functions. Its main function is to stimulate lactation after delivery, and it is common for prolactin levels to increase substantially during pregnancy and breastfeeding in women.
Thyroid Hormones
Thyroid Stimulating Hormone (TSH)
Thyroid stimulating hormone (TSH) is a hormone produced by the pituitary gland that regulates the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3) by the thyroid gland. TSH levels increase when thyroid hormone levels are low, and decrease when thyroid hormone levels are high. Abnormal TSH levels can indicate problems with the thyroid gland, such as under or overproduction of thyroid hormones. It can also be a result of pituitary gland disorders.
Diabetes
HbA1c
Haemoglobin A1c (HbA1c), also known as glycated haemoglobin, provides a measure of average glucose levels in the blood over a longer period than a simple blood glucose test. When glucose attaches to the haemoglobin in red blood cells, it forms glycated haemoglobin, which can be used to estimate the average level of sugar in the blood over the preceding 2-3 months, as red blood cells have a lifespan of around 12-16 weeks.
Sampling special instructions
Prepare for your Erectile Dysfunction Blood Test by following the instructions contained within your kit. It is advised to collect your sample before 10 am. Refrain from consuming fatty foods for eight hours prior to the test, and fasting is not required. If you are using hormone gels, pessaries, patches, or tablets, it is recommended to choose a venous sample collection method to minimise the potential contamination observed with finger-prick tests. In case you administer any hormone supplements, ensure to wear gloves and avoid any contact with hormone substances for at least four weeks before the test. Hormones can penetrate deep into the skin and persist for weeks, even with rigorous handwashing. Two days before the test, do not consume biotin supplements, and if you have been prescribed such supplements, discuss with your doctor whether to discontinue them before the test.
