4 practical questions about antigens: Can you only do nasal swabs? What to do if you test positive

Why is it important to take a nasal swab for antigen testing? How do I determine the number of laps and depth?

In general, taking a nasal swab for antigen detection is usually more accurate.

The antigenic detection technique can be used to target both nasopharyngeal and oropharyngeal secretions, which are usually more abundant than oropharyngeal secretions, through information extraction. If our body is infected by a virus,Rapid antigen nasal swab the virus content in the nasopharynx will be significantly higher than that in the oropharynx, so it is necessary to extract the secretions from the nasopharynx for testing, which will make the test analysis results more comprehensive and accurate.

1. Nasal swabs can be used for people over 14 years of age.

Before sampling, the self-examiner wipes his/her nose with a tissue, holds the end of the nasal swab in his/her hand, raises his/her head slightly, inserts the nasal swab into one nostril, slowly pricks it along the nasal passage for 1-1.5 centimeters, rotates the swab against the nasal passage at least four times, and stays there for more than 15 seconds, and then repeats the above operation with the same swab in the other nasal passage.

Self-examiners aged 2-14 years were examined by other adults. The inferior nasal passage was 1 cm deep and adhered to until the nasal cavity was rotated at least four times and held for no less than 15 seconds. The same swab was repeated in the other nasal cavity. In addition, when taking the swab, be careful not to contaminate the head swab or possibly affect the results with false positives or false negatives.

2. What do I need to know about antigen testing for the whole family?

The following requirements should be noted:

Sterilization. Everyone before and after the operating system need to we use the enterprise flow of water or hand sanitizer to wash their hands.

Understand the testing process. Carefully read the antigen self-test kit support instructions and notes related to antigen self-testing.

Reagent Preparation. Check that the antigen self-test reagents are within the shelf life, and check that the contents of nasal swabs, sampling tubes, test cards, etc. are not missing or damaged. If reagents are expired or reagent contents are missing or damaged, replace the test reagents promptly.

Determine environmental temperature and humidity requirements. The general requirement for colloidal gold strip testing is to avoid abnormal results due to excessive cold, heat, or humidity at ambient temperatures of 14 °C to 30 °C. The test should be performed in an environment with a temperature range of 0.5 °C to 0.5 °C. The test should be performed in a temperature range of 0.5 °C to 0.5 °C. Remove the antigen test card and place it in a flat, clean area.

Help self-testers aged 2-14 years to take samples by avoiding hand contact with the swab head and sterilizing promptly.

Detection and analysis of negative results, after the use of all the nasal swabs, sampling tubes, test cards, etc. into a sealed bag after as a business general living waste classification and disposal; detection of positive results of the study, in the transfer of personnel together with medical services need to be in accordance with the country's medical waste disposal.

3. How to help disabled family members, infants and children antigen test?

Disabled family members:Testing timing issues. Testing of disabled family members is not recommended unless necessary. If they do have symptoms of infection, it is recommended that they test themselves at home. Care should be taken to help them get tested. Two people in the family work together to help the family member with a disability sit up, then one person makes sure the head is fixed while the other collects a nasal swab. During this process, it is necessary to ensure that the collection rod is parallel to the nasal septum. After the test, take care to disinfect your hands and dispose of the medical waste in a sealed container.

Infants and young children: Infants and young children may instinctively resist the unknown. If your child is resistant to "nose poking" and "throat poking", you can explain the procedure to him in advance with videos or pictures, or by playing the roles of "little doctor" and "little patient". Practice in advance by playing the roles of "little doctor" and "little patient". Making sampling fun is the easiest thing for babies to accept. It will help to allay his fears and increase his cooperation. Before sampling your baby, parents should wash their hands and not test themselves and then give the test directly to your baby.

Always note that the antigen test stick should be parallel to the nose when doing the test. Before sampling, clean the nasal passages and blow your nose to facilitate sampling. Different antigen kits have different requirements for sampling, including nasal swabs and throat swabs. Parents must follow the instructions when using them.

4. If a positive study result is measured, how can I effectively avoid spreading the infection to others?

At the end of the self-test, the test results are all negative and disposed of as general trash by using sealed bags of sampling swabs, sampling tubes and test cards.

Positive test results should also be put into a sealed bag, but should be handed over to the medical institution as medical waste for disposal; at the same time, the domestic garbage should be sprayed with chlorine-containing disinfectant, and the disinfection time should be about 30 minutes.

Positive patients at home, need to have not been wearing a mask and live in their own independent room; after using the toilet, their own bathroom can be sprayed to disinfect and quickly back to the house, half an hour through other needs between family members can not meet the use; pay attention to the ventilation of the family and to ensure that the sunshine.
