    What does CST4 do?

    CST4, the full name of human cysteine protease inhibitor S (CST4), is a gastrointestinal tumor marker exclusively developed by our company and the first in the world.

    2
    How soon can I receive the test report?

    Usually 5 working days.

    3
    The accuracy of CST4 products?

    Clinical trials conducted by Peking Union Medical College Hospital etc. show that the sensitivity of our test is 60.4%-64%, and the specificity is 82.7%-83.4%. The data is accurate and reliable and can be used for the screening of gastrointestinal tumors.

    4
    Who are the high-risk groups of gastrointestinal tumors?

    Symptoms of gastrointestinal discomfort;

    People with chronic gastrointestinal diseases;

    Middle-aged and elderly people in high-incidence areas of gastrointestinal cancer (over 40 years old);

    Patients with gastrointestinal cancer after surgical treatment;

    family members of patients with gastrointestinal cancer;

    Patients with familial gastrointestinal adenomatosis.

    5
    The principle of CST4 products?

    Studies have found that with the growth, invasion and metastasis of gastrointestinal tumor cells, the expression of CST4 increases, and a higher concentration of CST4 protein can be detected in the serum of patients with gastrointestinal tumors, with high organ specificity and early detection rate. By detecting the expression of CST4, early screening, auxiliary diagnosis, curative effect evaluation and disease monitoring of gastrointestinal cancer can be completed.

    6
    Sampling considerations?

    Avoid eating high-fat, high-protein foods within 8 hours before the test;

    Female customers should try to avoid blood during menstruation (if there are special circumstances, please inform customer service or indicate in the health questionnaire);

    Fasting blood collection;

    7
    How are samples handled?

    Use a coagulation-promoting blood collection tube (yellow cap with separating gel), and collect 5 ml of peripheral blood. After sampling, turn the blood collection tube upside down and shake it gently for 5 times to fully fuse the solution in the tube with the blood sample. About 30min, no more than 2h at the latest), centrifuge at 4000rpm for 5min, aspirate the serum, transfer it to a 2mL centrifuge tube, label the centrifuge tube and blood collection tube with customer information, and transport to the corresponding laboratory for testing.

    8
    Is it okay to have a negative test result?

    If your test result is negative, it means that there is no obvious abnormality of gastrointestinal tumor protein markers in your test sample. We recommend that you maintain good living habits and undergo regular screening.

    However, our test items cannot cover 100% of related tumors. If you have obvious gastrointestinal symptoms, we still recommend you to go to the hospital for related examinations.

    9
    A positive test result must have a tumor?

    Not necessarily an existing tumor. A positive result indicates that abnormal gastrointestinal tumor protein markers were detected in this sample, and there is a high risk of malignant gastrointestinal tumors in the body.

    2
    How soon can I receive the test report?

    Usually 10 working days.

    3
    Precautions before testing

    It is advisable to have a light diet 3 days before blood collection, avoid meat and greasy food 1 day before blood collection; maintain a normal daily routine and avoid overwork and staying up late;
    Morning blood is collected on an empty stomach before 10:00 in the morning, and the fasting time is required to be more than 12 hours (fasting after 20:00 the day before);
    Do not do strenuous exercise before blood collection, relax your mind, and avoid abnormal emotional fluctuations;
    Female customers should try to avoid blood during menstruation and pregnancy (if there are special circumstances, please inform customer service or indicate in the health questionnaire);
    Avoid taking blood on the day of taking medicine (including traditional Chinese medicine, western medicine) or health care products. Avoid blood samples from people who have received an allogeneic blood transfusion within one year or a bone marrow transplant within two years.

    4
    Who is suitable for lung clearing?

    Clients with lung nodules detected on chest X-ray or CT.

    5
    Product price is too high

    Because the detection method of lung clearing products is to use next-generation deep sequencing technology (NGS) and tumor-derived exosome targeted capture and miRNA detection technology (Ultra-miRs PCR) at the same time. Capture the trace amount of circulating tumor DNA fragments (ctDNA) as low as 0.1% and trace exosomes released by cancerous cells in peripheral blood for detection, and in-depth detection (10000x) of 50 genes and exosome markers highly related to lung cancer. Reliably, safely, non-invasively, and conveniently provides information about the release of pulmonary nodule lesions into peripheral blood, assisting and excellent clinical comprehensive diagnosis. With a relatively high technical threshold, the cost will be relatively high; because it is a testing technology independently developed by Microdiag, the price of this product will be more competitive compared to other testing products of the same type in the industry.

    6
    What is lung clearing?

    Feijingqing is a combined detection of ctDNA + exosomes for auxiliary risk assessment of benign and malignant pulmonary nodules.

  • Liquid biopsy related issues
    1
    What is ctDNA?

    ctDNA (circulating tumor DNA) is tumor cell DNA that carries tumor-specific information and is a marker of tumors scattered in the blood. Through ctDNA detection, tumor traces in the blood can be detected.

    2
    How soon can I receive the test report?

    Usually 10 working days.

    3
    Why do tumor (ultra) early screening?

    Although the current tumor treatment technology and methods have made great progress, the mortality rate of most cancers is still high. Clinical studies have found that 90% of patients with tumors detected early can be cured. However, due to the limitations of conventional detection techniques, only a small number of people are diagnosed with cancer at an early stage. In my country, early (stage I) cancer patients account for about 5% to 10% of the total number of patients, and 70% of the patients are late detection and lost The best time for treatment, the 5-year survival rate is only 10%-30%. Therefore, early detection is the key to cancer treatment.

    4
    What types of tumors can a liquid biopsy cover?

    18 types of tumors can be screened at one time, divided into 18 males and 18 females.

    Men: Testicular cancer, prostate cancer, penile cancer, throat cancer, lung cancer, liver cancer, pancreatic cancer, stomach cancer, esophagus cancer, kidney cancer, thyroid cancer, colorectal cancer, bladder cancer, nasopharyngeal cancer, oral cancer, gallbladder cancer, brain cancer Glioma, osteosarcoma

    Women: ovarian cancer, endometrial cancer, breast cancer, cervical cancer, lung cancer, liver cancer, pancreatic cancer, stomach cancer, esophagus cancer, kidney cancer, thyroid cancer, colorectal cancer, bladder cancer, nasopharyngeal cancer, oral cancer, gallbladder cancer , glioma, osteosarcoma

    5
    Who is suitable for liquid biopsy?

    People with chronic inflammation or precancerous lesions, such as hepatitis, chronic ulcer disease, diabetes, gastrointestinal polyps, cervical erosion, breast cystic hyperplasia, thyroid nodules, etc.;

    People with bad habits, such as long-term smokers, alcoholics, people who hold back urine, people who often stay up late, people who eat meat, people with vitamin deficiencies, people who often drink hot boiled water, people with low cholesterol and other factors;

    Immediate family members of cancer patients;

    Allergic;

    engage in high-risk occupations;

    Over 45 years old, living in a big city for a long time, occupation with high work pressure;

    Prolonged exposure to hazardous chemicals or radiation for occupational and environmental reasons;

    Long-term smokers, drinkers, and excessive intake of high-fat foods lead to obesity.

    6
    Sampling considerations?

    Avoid eating high-fat, high-protein foods within 8 hours before the test;

    Female customers should try to avoid blood during menstruation (if there are special circumstances, please inform customer service or indicate in the health questionnaire);

    You can eat properly, please fill in the "Health Test Form" carefully;

    7
    How are samples handled?

    Use a special non-invasive blood collection tube (brown rubber head cover) to collect 10ml of peripheral blood. After sampling, turn the blood collection tube upside down and shake it gently for 10 times to fully integrate the solution in the tube with the blood sample. The blood collection tube is pasted with customer information and transported to Suzhou General Hospital at room temperature. Tested by Remed Laboratory.

    8
    Is it okay to have a negative test result?

    The absence of mutations in the test result does not necessarily mean that there is no tumor. Our test items are not yet able to cover 100% of related tumors, and it is estimated that about 10%-20% may be missed. The genes we detect are all organized based on data from clinical research results, and the accuracy of this technology will become more and more precise as relevant gene mining is supplemented.

    9
    A positive test result must have a tumor?

    A mutation in the test result is not necessarily a pre-existing tumor. Our test results have gene mutations, indicating that cancer (changed) cells already exist in the body. As for whether a tumor has formed, further examination is required to determine.

    10
    What to do if early screening detects genetic mutations?

    For tumor mutation carriers detected by ultra-early screening, we recommend going to the hospital for further examination by imaging methods such as PET-CT to determine whether a tumor has formed.

    If it has already formed, it needs to be clinically treated by means of hospital surgery, radiotherapy and chemotherapy. If no tumor is found, it indicates that the tumor mutation carrier is in a state of precancerous lesions, and certain preventive intervention measures need to be taken to make the mutant gene return to normal and prevent the further development of cancer.

    11
    After the liquid biopsy test showed that there was a mutation, the cancer was not detected in the ho

    If the test results have mutations, and the results of in-depth examinations such as hospital imaging, tumor markers, and organ function are "no abnormality", we preliminarily judge that they are precancerous and have not yet reached the stage of malignant tumors visible on imaging. This stage is still in the "latency period" (precancerous stage) of cancer. According to individual differences, improve bad living habits, stay away from carcinogens, and use appropriate interventions.

    12
    Is ultra-early detection the same as susceptibility detection?

    Different. For susceptibility testing, the samples tested are normal cells in any part of the human body, such as oral mucosa. The test result only reflects the possibility that the patient is more likely to get cancer than the average person because of heredity. It has nothing to do with the current state of the body. It is only a susceptibility risk. A positive test does not indicate that the subject is cancer. precancerous lesions or cancer.

    Ultra-early screening detects mutated genes specific to the tumor. The sample tested is DNA specific to tumor cells. The person whose mutation is detected is called a tumor gene mutation carrier, indicating that the person is in precancerous lesions, or is already a tumor patient. In people with precancerous lesions, we can make it possible to reverse it by means of intervention. Patients diagnosed with cancer by the hospital are recommended to go to clinical treatment.
