Low T (Testosterone) Blood Test

Low testosterone (low T) can affect men of any age: find out if it affects you with a simple at-home blood test.

Is it for you?

Are you experiencing symptoms which you think might be related to low testosterone? Are you getting older and wondering whether the “male menopause” is affecting you, or are you still young but feel that your energy, mood, and libido could be higher? If so, this simple home blood test could provide the answers you need.
Blood sample 1 test included 2 working days turnaround


  • You have symptoms which you think may be caused by low T (testosterone) including low libido and erectile dysfunction
  • You have noticed that you are finding it difficult to build muscle in the gym
  • You have low mood and difficulties sleeping
  • You feel you have lost your "get up and go"
It can be difficult in the UK to diagnose low T (testosterone) as many men may not attribute the symptoms they are experiencing to low testosterone. Unlike in women, where the fall in reproductive hormones and associated symptoms that occur during menopause is well known, the variety of symptoms a man may experience are not widely known, and therefore a man is less likely to seek help. Testosterone is responsible for male characteristics such as the maturation of the reproductive system and sperm production, libido, muscle mass and hair growth. Testosterone levels fall naturally after the age of 30, and this decline can lead to symptoms of what is known as the male menopause or andropause. Although low T is more likely to affect older men, younger men can be affected too.

Symptoms which can be associated with low T include:

  • Low libido (sex drive)
  • Erectile dysfunction
  • Sleep disturbance
  • Fatigue
  • Hair loss
  • Depression, low mood and motivation

Many of these symptoms can also be caused by other conditions so ruling out low T with a simple take-at-home blood test can be an important first step.

Your testosterone levels will be highest in the morning so you should take your Low T blood test shortly after you wake up. If your testosterone is found to be low, our doctors will normally recommend a repeat test to confirm. You may be able to boost your testosterone levels naturally, but for some men it is helpful to take testosterone replacement thereapy (TRT) to restore their testosterone to the normal range. 

This test is for men who believe that they may have low testosterone or for men who are taking TRT to maintain their testosterone level within the normal range. It is not suitable for men who are taking testosterone or anabolic steroids if they believe that they might have testosterone levels which exceed 52 nmol/L as this test will not give a reading above that level. Our Testosterone test has an extended upper limit and is suitable for men who may have supranormal levels of testosterone. 

Please ensure your sample is collected in the morning.
