Parents of new students in grade 2022:
Hello! Registration for new students in the fall of 2022 is about to begin, and the entrance tuberculosis screening physical examination is a ticket for new students to enroll. New students must go to a designated medical institution to undergo a tuberculin skin test screening before enrolling. If your child is about to enter junior high school or high school in Jinniu District, Chengdu , you can start booking the time and place for screening from now on. The relevant matters are as follows:
1. Skin test screening time and place
2. Skin test screening Items (need to be selected by parents on site)
1. Tuberculin test (PPD) : The detection reagent is pure protein derivative (PPD), which is currently the main method for screening tuberculosis . It must be conducted by medical staff 72 hours after the skin test. Interpretation of results.
2. New tuberculin test (EC) : The detection reagent is recombinant Mycobacterium tuberculosis fusion protein (EC). The injection site and method are the same as PPD. The results must be interpreted by medical personnel 72 hours after the skin test. EC is not affected by BCG. Vaccination effects.
Both of the above two reagent tests can determine whether the body is infected with tuberculosis bacteria.
3. Screening methods for special circumstances
If students are unable to undergo tuberculin skin test due to physical reasons ( acute infectious diseases , acute conjunctivitis , acute otitis media , systemic skin diseases and severe allergies , and other situations where the doctor determines that the tuberculin skin test is not suitable for the time being), you can choose .Y-interferon release test (IGRA) : Y-interferon release test (IGRA) is an in vitro detection technology. There is no need to pass a skin test, but by drawing blood to simulate the human body's response to Mycobacterium tuberculosis antigen stimulation in vitro to detect whether the body has been infected with Mycobacterium tuberculosis. IGRA is not affected by BCG vaccination, and its results have high sensitivity and specificity. The Y-interferon release test (IGRA) is completed by parents taking their students to the Chengdu Public Health Center (consultation phone number: 84521550). The gamma-interferon release test (IGRA) is the only physical examination method that can replace the tuberculin skin test for screening for tuberculosis infection. The disadvantage of is that is more expensive than skin testing. Tuberculosis antibody testing or direct chest x-rays are not a substitute for tuberculin skin test results.
4. In which case a chest X-ray examination is required
1. Tuberculin test (PPD): The doctor determines that the result is strongly positive . 2. New tuberculin test (EC): The doctor determines that the result is positive . 3. Y-interferon release test (IGRA): the result is positive . In the above three situations, chest X-ray examination is required to further judge the status of tuberculosis infection.
