Informed Consent for Testing COVID-19

The detection of viruses 2019-nCov or SARS-CoV-2 by sampling the nasal cavity (Nasopharyngeal swab) might cause a risk to medical staff whom expose to infected patients. It may also cause bleeding and wound within the nasal cavity during the sampling procedure.

Therefore, individually checking for infections by taking the sputum and saliva samples is another way to reduce the risk for healthcare providers. Person does not need to take a risk of receiving wound or bleeding from the nose sampling procedure. It is also convenient for people not having to leave their residents to visit hospital which will help reduce their risk of infecting or spreading the virus during the whole process.

The accuracy of detecting SARS-CoV-2 from saliva is up to 90% (Referred to Consistent Detection of 2019 Novel Coronavirus in Saliva, Clinical Infectious Disease, ciaa149, http://doi.org/10.1093.cid/ciaa149). The Department of Health, Ministry of Public Health (Thailand), states that COVID-19 pathogens detected in saliva are as high as 88.6% second to only in nasal mucous. Yet, any laboratory testing may show inconclusive result due to many factors including inaccurate sampling.

Therefore, please sign your name below to express your informed consent;

I agree to take my own saliva samples for checking the pathogen SARS-CoV-2 in the standard laboratory certified by the Department of Medical Science, Ministry of Public Health (Thailand) and I accept the small discrepancies that may occur based on the previous statements.

In case the result is reported positive meaning you are infected with SARS-CoV-2, the inspection institute has the right to redirect your test result to the Department of Disease Control, Ministry of Public Health (Thailand) as Communicable Disease Act announced by National Communicable Disease Committee 2015. Moreover, you agree to travel to the hospital as directed by the Ministry of Public Health (Thailand) to take part in the checkups, quarantine, or isolation, based on your situation as announced by the Department of Disease Control, Ministry of Public Health (Thailand).
