The GASTROClear, an in-vitro diagnostic medical device (IVD), is intended for use as an adjunctive test for the detection of gastric neoplasia associated miRNA biomarkers in human serum. GASTROClear is NOT intended as a replacement for gastroscopy; it should be used in conjunction with gastroscopy and other test methods in accordance with recognised clinical guidelines. It is thus an adjective tool to aid in the detection of gastric cancer.
As such, only patients who met certain criteria are tested using GASTROClear. The result obtained from the test may indicate the presence of gastric cancer and the patient then goes for gastroscopy and biopsy as required. The output of the GASTROClear test is a risk score where a high score may indicate the presence of gastric cancer and should be followed up by gastroscopy.
