About the applicable department?

Medical technology department: laboratory department, pathology department, molecular diagnosis center, central laboratory;

Clinical departments: Gastroenterology, gastrointestinal surgery, anorectal, oncology, geriatrics, endocrinology;

Medical center;


About the sample size?

5-10g stool sample;


About detection steps and time?

The detection process includes four steps: sample processing, nucleic acid extraction, transformation and purification, and qPCR, and the required time is 0.1h, 1.34h, 1.9h, and 1.16h, respectively;


About results quality control standards and interpretation standards?

Quality control standard:

Sample validity: ACTB≤36, positive control: 26≤Ct≤30, negative control: Unde or Ct≥40;

Detection and interpretation standards:

Both genes were interpreted according to the following standards

Ct value ≤38 is positive

Ct>38 or Unde is interpreted as negative

Sample Interpretation Criteria:

SDC2 or TFPI2 is positive, that is, the judgment result is positive

Both SDC2 and TFPI2 are negative, that is, the judgment result is negative


About sample test results?

If the sample test result is positive, it means that the subject has a high risk of colorectal cancer or precancerous lesions at the time of sampling, and other tests such as colonoscopy are recommended to confirm the diagnosis;

If the test result of the sample is negative, it means that the risk of colorectal cancer or precancerous lesions of the subject is low at the time of sampling, but the risk of the disease cannot be completely ruled out. It is recommended to retest every 1-3 years. The actual situation of the tester recommends colonoscopy;
