roGRP antigen antibody is an immunological assay for the detection of ProGRP(a precursor of gastrin releasing peptide).

ProGRP is an important regulatory molecule associated with many physiological functions and pathological states of human body. It is a gastrointestinal hormone, a mammalian homologous amphibian frogskin, originally isolated from the gastric mucosa of pigs, and widely distributed in the nervous system, gastrointestinal tract and respiratory tract of mammals.

ProGRP is a precursor of gastrin releasing peptide, a proliferating factor in small cell lung cancer. As a marker of small cell lung cancer, ProGRP has the following characteristics: 1. It is highly specific for small cell lung cancer; 2. 2. Early cases have a higher positive rate; 3. The blood concentration of healthy people and patients is very different, so the reliability of detection is very high.

Therefore, for patients suspected of having small cell lung cancer, doctors may recommend ProGRP antigen antibody testing to aid diagnosis.
