TSH: We examine the levels of the thyroid-stimulating hormone, TSH, which is produced in the pituitary gland and stimulates thyroid hormone production. If the TSH value is elevated, we talk about hypothyroidism, and if the TSH value is lower, hyperthyroidism might be in the background.
Bilirubin: is produced as a yellow breakdown of red blood cells in the spleen, liver and certain lymph nodes. Its levels can be elevated in case of increased red blood cell breakdown, liver disease and cholestasis. The development of cholestasis is often common with the use of illegal performance enhancers.
GOT (glutamate oxaloacetate aminotransferase): an enzyme involved in the metabolism of amino acids. Normally, it is present in small amounts in the blood, in case of intensive training or muscle damage, its level may increase, and this elevated level may indicate other organ damage.
GPT (glutamate pyruvate aminotransferase): an enzyme produced in liver cells that shows the damage that has taken place there. Normally, it is also present in small amounts in the blood, in case of trauma, or during intensive training, or in case of muscle injury, its level may increase.
GGT (gamma-glutamyltransferase): an enzyme produced by the liver, pancreas, and kidneys. Its value is checked when examining the liver and bile ducts, it is the most reliable indicative parameter. Its elevated value indicates blockage of the bile ducts.
Alkaline phosphatase (ALP): an enzyme that helps break down proteins. It usually provides information when examining liver and bone diseases. A high value indicates liver or bone disease (e.g. osteoporosis), a lower value may be due to hypothyroidism, malnutrition, or anaemia.
