The importance of informing your doctor about your usual exercise and sports routines.

Blood and urine tests are essential diagnostic tools. They allow healthcare professionals to assess organ function, identify deficiencies, detect diseases in their early stages, and monitor response to treatment. For these tests to perform their function most effectively, specific prerequisites are often required. These may include fasting, restriction of certain foods, medication regimens, and considerations regarding sports, exercise, and physical activity. Ignoring these guidelines can lead to falsified results, generating confusion, false diagnoses, or the need to repeat the test. However, the relationship between exercise and blood test results depends largely on the intensity and type of physical activity performed, as well as the time elapsed between exercise and sample collection. When we subject our muscles to significant stress, natural microscopic damage occurs in muscle fibers. As part of the repair and adaptation process, certain substances present within muscle cells are released into the bloodstream. These substances can be detected in blood and urine tests, and elevated levels can be misinterpreted as indicators of a pathological condition.
