The scope of the complete set of biochemical tests includes liver function, kidney function, cardiac enzyme profile, blood lipids, blood glucose, and ion analysis. These test indicators can further clarify the situation related to liver, kidney, blood sugar, blood lipids, and heart. If there are abnormalities in liver function, such as elevated transaminases and bilirubin, this is still a case of liver cell damage, and the most common causes are fatty liver, alcoholic liver, hepatitis B virus infection, cirrhosis, and even liver cancer. In the case of abnormalities, further tests of alpha-fetoprotein, hepatitis B five, abdominal ultrasound, and even abdominal CT are needed to further clarify the specific cause. If the kidney function is abnormal, such as creatinine and urea nitrogen are significantly elevated, there may be kidney stones, hydronephrosis, other stones in the urinary tract, and renal insufficiency, etc. Further ultrasound, urine routine, and CT examination of the urinary tract are needed. If the cardiac enzyme profile is significantly elevated, accompanied by severe pain in the precordial region and a history of inadequate blood supply to the heart, it is likely that there is an acute myocardial infarction, which requires immediate hospitalization and, if necessary, stent placement to save lives.
