High pre-collagen type III amino-terminal peptide may indicate hepatitis, cirrhosis and other diseases. Type III precollagen amino-terminal peptide is the N-terminal peptide of type III precollagen released by peptidase, and it can be used to reflect the degree of hepatic fibroplasia in clinical practice. Blood is collected from a vein to determine whether the value is abnormal, and the normal value is 41~163μg/L. If the patient’s value is high, it is considered to be caused by liver disease. Higher amino-terminal peptide of type III precollagen may be caused by chronic alcoholic hepatitis, chronic active hepatitis, cirrhosis, hepatocellular carcinoma and other diseases, as well as rheumatoid arthritis, systemic lupus erythematosus, pulmonary fibrosis and other diseases. Test results need to be analyzed and judged comprehensively under the guidance of a medical professional based on the patient’s own condition, as well as medical history and physical signs. Once diagnosed, patients can take relevant treatment measures under the guidance of doctors to avoid delaying the condition and damaging health.
