The Case Of Viral Pneumonia Was First Detected In 2019, And The New Coronavirus (COVID-19) That Caused The Disease Was Discovered. On January 12, 2020, The New Viral Pneumonia Was Named "COVID-19" By The World Health Organization And The Corresponding Virus Was Named "SARS-CoV-2". The Virus Is Coated With Round Or Elliptical Particles, Which Are Polymorphic With A Diameter Of 60-140nm. Its Genetic Characteristics Are Significantly Different From SARSr-CoV And MERSr-CoV And Have More Than 85% Homology With ß-SARS- Like Coronavirus (ß-SL-CoVZC45). The Virus Can Be Excreted Through Respiratory Secretions And Spread Through Saliva, Sneezing, Contact And Aerosols.

SARS-CoV-2 Antigen Test Kit (Saliva) (Colloidal Gold) Use The Double-antibody Sandwich Method To Qualitatively Detect SARS-CoV-2 In Saliva.

Testing Principle Of SARS-CoV-2 Antigen Test Kit (Saliva) (Colloidal Gold)
SARS-CoV-2 Antigen Test Kit (Saliva) (Colloidal Gold) Is The Kit Based On Nitrocellulose Membrane And Qualitative Immunoassay To Detect SARS- CoV-2 In Saliva.

During The Test, Add The Saliva Sample To The Buffer And Mix Well.

After Adding It To The Sample Well, It Will React With The Bound SARS-CoV-2-N22 Antibody-coated Gold Nanoparticles To Form An Antigen-antibody Complex.

This Complex Migrates Forward Along The Test Strip On The Chromatographic Membrane, Interacts And Binds With The Immobilized SARS-CoV-2-N21 Antibody, And Immobilizes The Antigen In The Test Line Area Of The Test.

If The Specimen Contains SARS-CoV-2, A Color Line Will Appear In The Test Line Area, Indicating That The Result Is Positive.

Otherwise, There Will Be No Color Line In The Area, Indicating A Negative Result. In Order To Determine The Validity Of The Test Strip, A Color Line Will Always Appear In The Control Line Area, Indicating That An Appropriate Volume Of Sample Has Been Added And Reacted With The Quality Control Antibody On The Membrane.
