影响化验结果的因素很多,除了饮食、检验技术、实验方法等外,药物也是一个重要的因素。许多药物进入人体后,可引起人体生理、生化和病理方面的复杂变化(这些变化并非原发病所致),从而影响化验结果;另一些药物由于其物理化学性质可与检验试剂起反应,从而干扰化验结果,出现假阳性、假阴性或多种无法解释的结果。这不仅影响了化验的准确性和可靠性,而且会使医师诊断困难,贻误病情和治疗,严重者可危及生命。
There are many factors that affect the test results. In addition to diet, testing techniques, and experimental methods, drugs are an important factor. Many drugs can cause complex changes in human physiology, biochemistry, and pathology (which are not caused by the primary disease) after they enter the human body, affecting the test results; other drugs can react with test reagents because of their physical and chemical properties. Disturbance test results, false positives, false negatives, or multiple unexplained results. This not only affects the accuracy and reliability of the tests, but also makes it difficult for doctors to diagnose, delay illness and treatment, and severe cases can be life-threatening.
