Gastrin-releasing peptide precursor 96.74 is generally relatively serious. Gastrin-releasing peptide precursor (ProGRP) is a tumor marker test. The normal value of Gastrin Releasing Peptide Precursor is 46ng/L. If it is greater than the normal value, further examination is needed. It is recommended that the test and treatment be performed under the supervision of a doctor. When gastrin-releasing peptide precursor is high, it is suspected to be small-cell lung cancer, digestive tract mass, etc. However, it needs further examination such as CT, pathological biopsy, etc., and supplemented with clinical symptoms of respiratory and digestive tracts, etc. for a comprehensive examination before diagnosis can be confirmed. In addition, some benign diseases can also cause high gastrin-releasing peptide precursor (e.g. gastritis, gastric ulcer, etc.). People who find elevated gastrin-releasing peptide precursor after examination need to undergo further examination to clarify the specific cause of the disease and then treat the cause.
