Novel Coronavirus 2019-nCoV Detection
What is coronavirus?
•Coronaviruses are a large family of RNA viruses includingHCoV-229E, OC43, NL63, and HKU1 that usually cause mildrespiratory illnesses with the exceptions of the fatal SevereAcute Respiratory Syndrome Coronavirus (SARS-CoV) and theMiddle East Respiratory Syndrome Coronavirus (MERS) of thelast two decades.
•A recent outbreak of pneumonia in Wuhan, China declaredon December 12th, 2019, led to the isolation and identificationof a new human coronavirus, 2019-nCoV (SARS-CoV-2), as theresponsible agent of this new acute respiratory syndrome. Thisvirus can cause the disease named coronavirus disease 2019(COVID-19). WHO refers to the virus as COVID-19 virus in itscurrent documentation.
According to WHO; globally more than 15 million COVID-19 cases were confirmed, andmore than 640 thousand deaths were reported. The cases are reported from 216countries, areas or territories.

COVID-19 Testing
According to CDC; two kinds of tests are available for COVID-19: viral tests and antibody tests.
•A viral test tells you if you have a current infection.•An antibody test tells you if you had a previous infection.
Who should be tested?
Most people will have mild illness and can recover at home without medical care and may not need to betested. CDC has guidance for who should be tested, but decisions about testing are made by healthdepartments or healthcare providers.
How to collect samples?
According to CDC Guidelines; specimens should be collected as soon as possible once a decision has been made topursue testing, regardless of the time of symptom onset.
For initial diagnostic testing for SARS-CoV-2, CDC recommends collecting and testing an upper respiratory specimen.The following are acceptable specimens:
•A nasopharyngeal (NP) specimen•An oropharyngeal (OP) specimen•A nasal mid-turbinate swab (using a flocked tapered swab)•An anterior nares (nasal swab) (using a flocked or spun polyester swab)• Nasopharyngeal wash/aspirate or nasal wash/aspirate (NW)
Swabs should be placed immediately into a sterile transport tube containing 2-3mL of either viral transport medium(VTM), Amies transport medium, or sterile saline, unless using a test designed to analyze a specimen directly, (i.e.,without placement in VTM).

COVID-19 Detection Methods
Immunoassays Molecular Assays
Serologic assays for SARS-CoV-2, now broadly available.These assays can play an important role in understandingthe virus’s epidemiology in the general population. Unlikeviral direct detection methods such as nucleic acidamplification or antigen detection tests that can detectacutely infected persons, antibody tests help determinewhether the individual being tested was ever infectedeven if that person never showed symptoms.
Serologic tests detects SARS-CoV-2 virus infectionindirectly therefore these tests cannot typically replacedirect detection methods as the primary tool fordiagnosing an active SARS-CoV-2 infection. But they arevery important for monitoring and responding to theCOVID-19 pandemic.
Currently, there is no identified advantage of theseassays whether they test for IgG, IgM and IgG, or totalantibody.
The preferred testing method is the real-time reversetranscription-PCR (RT-PCR) test. These tests detectsSARS-CoV-2 virüs directly. Within 5 to 6 days of theonset of symptoms, patients with COVID-19 havedemonstrated high viral loads in their upper and lowerrespiratory tracts. A nasopharyngeal (NP) swab and/or anoropharyngeal (OP) swab are often recommended forscreening or diagnosis of early infection.
Results are for the identification of SARS-CoV-2 RNA.The SARS-CoV-2 RNA is generally detectable in humanoropharyngeal swab and nasopharyngeal swabspecimens during the acute phase of infection. Positiveresults are indicative of active COVID-19 infection.Laboratories are required to report all positive results tothe appropriate public health authorities.
Negative results do not preclude COVID-19 infection andshould not be used as the sole basis for patientmanagement decisions. Negative results must becombined with clinical observations, patient history, andepidemiological information.
