Introduction
Biochemical blood tests can be used for the preliminary diagnosis of acute and chronic hepatitis, gallstones, cholangitis, diabetes, chronic renal failure, and other diseases. It should be noted that if abnormal results are indicated by biochemical blood tests, further diagnostic analysis should be conducted in combination with other examinations, so that doctors can provide targeted treatment based on the specific cause. Meanwhile, regular follow-up during treatment is necessary to timely monitor the body's recovery status.
Generally, blood biochemical tests can be used for the preliminary diagnosis of diseases such as acute and chronic hepatitis, gallstones, cholangitis, diabetes, and chronic renal failure. If experiencing any discomfort, it is recommended to seek medical attention promptly. Detailed analysis is as follows:
1. Acute and Chronic Hepatitis
Acute and chronic hepatitis are usually associated with hepatitis virus infection, drug side effects, alcohol consumption, and other factors. Patients mainly experience symptoms such as yellowing of the skin and sclera. Blood biochemical tests may indicate elevated total bilirubin levels and increased alanine aminotransferase (ALT) and aspartate aminotransferase (AST).
2. Gallstones
Gallstone formation may be related to factors such as consuming high-purine foods and lack of physical activity. These factors can lead to excessive cholesterol accumulation in bile, thereby affecting gallbladder emptying. Common symptoms include biliary colic, nausea, and vomiting. Blood biochemical tests may reveal elevated total bilirubin levels.
3. Cholangitis
Cholangitis is caused by biliary obstruction or bacterial infection. Patients mainly experience symptoms such as abdominal pain, jaundice, and high fever. During the aforementioned tests, elevated total bilirubin levels may be found. When liver health is affected, increased levels of ALT and AST may also be indicated.
4. Diabetes
Diabetes is often associated with genetic and environmental factors. Patients may exhibit the "three highs and one low" symptoms, characterized by increased thirst, frequent urination, increased appetite, and weight loss. According to blood biochemical test results, patients' fasting blood glucose and postprandial 2-hour blood glucose levels are higher than normal values, and glycated proteins are elevated.
5. Chronic Renal Failure
Chronic renal failure is usually associated with factors such as chronic glomerulonephritis and diabetic nephropathy. When kidney function is impaired, patients may experience symptoms such as fatigue, loss of appetite, and body edema. The aforementioned tests may reveal elevated serum creatinine and blood urea nitrogen levels, indicating possible progression to the uremic phase of chronic renal failure.
It should be noted that if blood biochemical tests indicate abnormalities, other tests should also be considered for comprehensive diagnostic analysis, allowing doctors to provide targeted treatment based on specific causes. Additionally, regular follow-up visits should be conducted during treatment to monitor the recovery process promptly.
