Covid-19 latest information

There are currently two types of test for the Coronavirus Disease(COVID-19) in HK: diagnostic test and antibody test (or serum tests)

Diagnostic test can show if you have an active coronavirusinfection. There are two diagnostic tests: viral polymerase chain reaction(PCR) detection (or molecular detection), which can detect the genetic materialof the virus, and antigen detection, which can detect specific proteins on thesurface of the virus.

Antibody test can detect past infections. After infection,it may take 1 to 3 weeks for the body to produce antibodies. This method candetermine whether the patient has been infected, and how long it has beeninfected according to the type of antibody produced.


[Antigen Test]

Recognized by the World Health Organization (WHO), the U.S.Food and Drug Administration (FDA) and the European Union (CE), officiallyadopted by the California government, antigen detection uses lateral flowimmunoassay for direct detection of SARS-CoV-2 antigen in nasal swab samples,using the principle that each antibody only binds to the corresponding antigen(such as the correspondence between a lock and a key), as long as the antigen(lock) is stored in the sample, even if the amount is small, the antibody (key)can bind immediately, implying the existence of a virus.

Although the antigen detection rapid screening test is notlike the nucleic acid detection (PCR) principle, which can replicate a largeamount of viral RNA and amplify the infection signal, the sensitivity of antigendetection is relatively low, and there is a chance of false negatives at the initial stage of infection. However, the antigen test can be "tested andknown", in just 15 minutes; and if the test result is positive or symptomsbegin to appear, the accuracy is usually high, and the patient can takeimmediate safety measures, which is safer and faster than PCR test.


[Antibody Detection]

Antibody testing is to detect whether there are antibodiesin the blood by using synthetic viral antigens. After being infected,antibodies will appear in the patient's body. This method can determine whetherthe patient has been infected.

The principle of antibody detection test is like that ofantigen detection, except that it detects IgM and IgG antibodies in the blood.IgM antibody is the first kind of antibody that reacts when the human immunesystem encounters a viral antigen for the first time. It appears approximately1-2 weeks after infection and its concentration will decrease as it clears thevirus. Then, the body produces a second kind of antibody: IgG.

Therefore, on the antibody test, if only IgM antibodies arepositive, it means that the infected person is in the early stage of infection;if only IgG antibodies are positive, it means that they are in the lateinfection or recovery period; if both IgM and IgG antibodies are positive at the same time, it means that they are in the middle of the infection stage or thisis called the active period of infection and must be quarantined and undergofurther testing and treatment.


AttoHealth® Covid-19 Antigen and Antibody Rapid Test Kit

Launched by AttoHealth Medical, patient can be testedanytime and anywhere by himself, with an accuracy rate of ≥95%, and the testresults can be obtained in 15 minutes. The combination includes antigendetection and antibody detection. It is recommended that they should be used inconjunction with each other at the same time. You can do the test on your ownin about 3 to 7 days to have a more accurate detection of infection and thestatus.



Core advantages of AttoHealth® Covid-19 Antigen and AntibodyRapid Test Kit:

Comprehensive testing: Combining antigen and antibody testing to have morecomprehensively detection whether you are/have been infected with the virus,and how long the infection has been, to facilitate further testing andtreatment

Simpleoperation: no need to use special professional equipment and instruments, self-test at home, and can be used frequently

Fastresults: test results can be obtained in only 15 minutes

Highsensitivity: clinically verified sensitivity is above 96%

[Expert suggestion]

Dr. Kenneth Kwong, Doctor of Chemistry in the University ofHong Kong—

"Antigen test can be understood as testing the proteinin the outer layer of the Covid-19 virus. People at high risk should do moreself-testing to protect themselves and others."


Dr. Wilson Lam, Specialist in Infectious Diseases —

"Although the accuracy of home test kit is not as highas that of PCR test, the advantage of it is that people can do it at home andavoid the time-consuming PCR. Through repeated testing, the sensitivity of thetest and the accuracy of the test results can be improved. It serves as anacute diagnosis."


Dr. David Lam, Surgeon—

"Antigen test is a fast, self-service, and highaccuracy choice. Many hospitals have asked employees and doctors to do antigentest every week, and confirm the result to be negative before they work. TheHarvard study also pointed out that the antigen test is easy to use, where a fastdetection is more important than high accuracy."
