    I am very satisfied with the company and regularly load my blood tests. The only pity is that you don't get a confirmation when the blood has arrived. That would be an added value...

    Product Description


    This blood test measures the amount of testosterone in the blood.

    Due to fluctuations in day and night rhythms, morning blood sampling is recommended (approximately from 7:00 a.m. to 10:00 a.m.) in order to compare results.

    About Testosterone

    Testosterone is the male sex hormone made in men primarily in the testes. It stimulates the development of male sex characteristics such as the low voice, growth of the penis, body hair and muscle development. It also stimulates the desire for sex and provides firm bones.

    Testosterone is also made in the adrenal glands (in both men and women) and in small amounts in the ovaries (in women).

    Testosterone regulates much more than sex drive

    Men can do a lot themselves to boost their testosterone levels. Testosterone keeps a man's body healthy for a long time. In fact, the hormone has a lot to do with memory, osteoporosis, mood and cardiovascular disease.

    Older men with low testosterone have a higher chance of dying. Although it is not yet hard proven, studies indicate that older men with relatively high testosterone levels have more energy and are less prone to diseases of old age.

    Various problems

    Testosterone production slowly declines as we age. Because testosterone is at work everywhere in the male body, this means that a deficiency in the hormone can also cause various problems.

    From memory to bones

    In the blood of a healthy man, the concentration of testosterone fluctuates daily between 11 and 30 nanomol per liter. From the age of 40 men can notice that their muscle strength and muscle mass decrease slightly. This happens very gradually. The short term memory will slowly start to function less well and at a later age the sex drive will decrease. Problems with sleeping can also occur. There is a link between low testosterone and osteoporosis, but it is still unclear whether a low testosterone level causes osteoporosis or whether it is a consequence of it.

    Metabolic syndrome

    Low testosterone levels are also often seen in conjunction with what is known as metabolic syndrome. That syndrome is a combination of factors that can lead to cardiovascular disease. These include high blood pressure, excessive cholesterol, unfavorable blood sugar levels, arteriosclerosis and (extreme) obesity. Again, it is not clear whether low testosterone levels cause all this or are just a consequence. The real culprit may be the fat stored around organs.

    Organ Fat

    A growing body of research shows that deep abdominal fat negatively affects blood sugar and cholesterol levels. Deep belly fat or organ fat converts testosterone into the female hormone estrogen, which further promotes fat storage. As fat mass increases and muscle mass breaks down, the body becomes less sensitive to insulin and the risk of type 2 diabetes increases. Most men can reduce or even reverse this process for the better. They can boost their testosterone production again by changing their lifestyle.


    In women entering menopause, hormone levels change relatively quickly. This menopause does not really have a male counterpart. In men it is sometimes called penopause or andropause, when the testosterone level in the blood no longer exceeds 12 nanomol per liter. A deficiency occurs in almost 1 in 10 men between the ages of 40 and 79. All kinds of symptoms can occur, but they are not always noticed or associated with low testosterone. The main complaints are decreased libido, depressive feelings and osteoporosis.
