What can be detected by testing blood serum

Before the serum test, you need to be clear about what kind of discomfort you have and what data you need to know. You can also get a serum test based on the doctor's diagnosis and advice. Serum tests can generally reveal many aspects of the content, and the specific details need to be judged based on your own condition. You can ask your attending physician for relevant matters. The specific serum examination contents are introduced as follows.

Serum enzyme test:

1. Alanine aminotransferase (ALT) [normal reference value] rate method (enzyme method): 5-35IU/L. [Clinical significance] Increased levels are seen in acute hepatitis, chronic hepatitis, cirrhosis, cholelithiasis, liver necrosis, liver cancer, cholangitis, cholecystitis, myocardial infarction, heart failure, myocarditis, polymyositis, alcohol, chemical poisons, drugs and other factors that cause liver damage.

2. Aspartate aminotransferase (AST) [normal reference value] rate method (enzyme method): 10-36IU/L. [Clinical significance] Increased levels are seen in acute and chronic severe hepatitis, cirrhosis, myocarditis, myocardial infarction, nephritis, cholangitis, dermatomyositis and other diseases.

3. Alkaline phosphatase (ALP) [normal reference value] rate method: 50-170IU/L. [Clinical significance] Increased levels are seen in acute and chronic icteric hepatitis, obstructive jaundice, biliary stones, bile duct cancer, liver cancer, osteitis fibrosa, rickets, and the healing period of fracture repair.

4. Lactate dehydrogenase (LDH) [normal reference value] rate method: 55-135U/L. [Clinical significance] Increased levels are seen in hepatitis, myocardial infarction, pulmonary infarction, certain malignant tumors, leukemia, Sickness syndrome, shock, hemolytic anemia and other diseases.

Liver function tests:

1. Total bilirubin (TBIL) [normal reference value] Caffeine method: 0.3-1.Omg/dL. [Clinical significance] Increased levels are seen in diseases such as hemolytic, hepatocellular, and obstructive jaundice.

2. Direct bilirubin (DBIL) [normal reference value] hydrochloric acid method: 0-0.35 mg/dL. [Clinical significance] Increased levels are seen in cholelithiasis, cholangiocarcinoma, obstructive jaundice, and hepatocellular jaundice.

3. Indirect bilirubin (IBIL) [normal reference value] 0.3-0.7 mg/dL. [Clinical significance] Increased levels are seen in diseases such as hepatocellular jaundice.

4. Thymol turbidity test (TTT) [normal reference value] 0-6u. [Clinical significance] Increased levels are seen in diseases such as acute and chronic hepatitis.

Blood lipid test:

1. Serum total cholesterol (Tch) [normal reference value] 2.9-6.0mmol/L. [Clinical significance] Increased levels are seen in nephrotic syndrome, atherosclerosis, common bile duct obstruction, cholelithiasis, biliary tumors, diabetes, myxedema, etc. Decreased cholesterol synthesis is seen in hyperthyroidism, malignant anemia, acute severe hepatitis, and cirrhosis.

2. Serum cholesterol ester (CE) [normal reference value] 2.34-3.38mmol/L. [Clinical significance] Decrease is seen in patients with solid liver disease and indicates disease progression and poor prognosis.
