PCR would be chosen where there is a low likelihood of having the virus, but doctors want to be certain the patient doesn't have it. Antigen would be chosen if there is a high probability the patient has the virus (i.e. is experiencing symptoms), and doctors need to screen the patient as positive or negative.
The first type of PCR detection process includes multiple steps such as specimen processing, nucleic acid extraction, and PCR detection. The average detection time takes 2-3 hours. Because it directly detects the viral nucleic acid in the samples we collect, it has strong specificity and relatively high sensitivity and is currently the main detection method. The second type of antibody detection includes the colloidal gold method and the magnetic particle chemiluminescence method. The average detection time of the colloidal gold method is about 15 minutes, but if the serum is used instead of whole blood, the serum processing will take some time. Blood is about 15 minutes. The magnetic particle chemiluminescence method generally takes 30-60 minutes. Antibody detection is to detect the level of antibodies in human blood. In the early stage of infection, the human body may not produce antibodies, so it has a window period for detection. Therefore, antibody detection can be used to assist in the diagnosis of cases with negative nucleic acid tests, and can also be used for screening and screening, but it cannot replace nucleic acid detection methods.
Why choose the Swab Training & Demo Model?
➤ An Educational Model for Swab Collection Training & Demonstrations
It is an educational model that can be used to teach proper oropharyngeal & nasopharyngeal swabbing and learn the correct swab insertion and collection.
The key to a proper oral or nasal swab involves the direction and depth of the swab being inserted. And the swab test training model helps to exercise and solidify those swabber aspects.
Perfect test demonstrations in test sites, clinics, health facilities, doctor’s offices, and more.
➤ Accurate and Realistic
The carving model features openings to the sculpted nasal and oral cavities.
The head is tilted back slightly for easier access to the realistically sculpted nasal passages and throat as well as a clear observation of the procedures.
Mimic tissues and structures of the nasal and pharyngeal cavities. The swab training model is the most realistic one.
Why need a swab test training model?
Doctors are always struggling with how to train newcomers to find the correct swab position in PCR and antigen testing. After listening to the advice of doctors and friends, we decided to design a model for them to help guide newcomers on how to do PCR and antigen testing. We have been faced with the COVID pandemic since 2019. A nasopharyngeal or oropharyngeal swab and nucleic acid test are the best way to fast identify whether the patient is infected with COVID-19 nowadays. Thus early testing for COVID-19 remains essential for controlling the pandemic.
Swabbing is a new procedure for health professionals or healthcare workers who have never done it before or were not as familiar with it. With an ever-expanding number of screening tests, more and more healthcare professionals, whether or not properly trained in this procedure, are being called on to perform these tests. However, improper swabbing probably injures the patients or even produces false negative results. So the swab training model is carried out and becomes an essential educational tool to standardize the learning and improvement of NPS or OPS collection. Help to improve the skills of those performing the swabs and aid proper COVID testing.
