What is SARS-CoV-2?
Formerly, this disease was referred to as "2019 novel coronavirus" or "2019-nCoV". CoVID-19 is caused by a coronavirus called SARS-Cov-2. Coronaviruses are a large family of viruses that are common in people and many different species of animals. In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to move severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome(SARS)
Symptoms of CoVID-19
- Shortness of breath
- Trouble breathing
- Sore throat
These symptoms are usually mild and begin gradually. Some people become infected but only have verymild symptoms may appear 2-14 days after exposure to the virus.
Book Test Now To Early
Real Time RT-PCR is the gold standard test for detecting cases of CoVID-19. The test requires specialized laboratory setup with specific bio-safety and bio-security precautions to be followed as per NABL and ICMR guidelines

Understand RT-qPCR and Serological Test Results
Reverse Transription Quantitative Polymerase Chain Reaction (RT -qPCR)
The COVID-19 RT-PCR test is a real time reverse transription polymerase chain reaction (rRT-PCR) test for the qualitative detection of nucleic acid from SARS-CoV-2 in upper and lower respiratory specimens (such as nasopharngeal or oropharyngeal swabs, sputum, lower respiratory tract aspirates, bronchoalveolar lavage, and nasopharyngeal wash/aspirate) collected from individuals suspected of COVID-19.
Serological immunoassays - viral-specific antibodies (IgM and IgG) or antigens
A serologic test is blood test looks for antibodies created by your immune system. The serologic test for CoVID-19 specially looks for antibodies against the CoVID-19 virus. it can help in identity anyone who has recovered from coronavirus (by using IgG antibody testing) or has a recent and portentially active infection (by using IgM antibody testing)
Patient may be in the window period of infection
Patient may be in the stage of recovery
This table is based on the current knowledge about the rise and fall of SARS-CoV-2 RNA and antigens, IgM antibody and IgG antibody Figure and the correlation of these level variations with the initial time of infection, onset of symptoms and recovery phase. As shown in Figure, serological tests are recommended to be used on patients at least 3 days after onset of symptoms or 7-10 days after infection with the virus.

Frequently Asked Questions
Why should I use a separate test of SARS-CoV-2 IgG compared to a Total Antibody test?
An assay targeting the whole antibody response by all Immunoglobulin classes cannot reliably differentiate recent infections from more distant ones and may generate confusion on potential active infections vs. past infections, engendering the need for further testing steps on positives.
Epidemiologists and healthcare workers will need to further elucidate the type of immune reaction that is occurring when a positive signal for a total antibodies assay has been detected. In addition, total antibody results may lead to the misclassification of individuals in terms of time of infection. As further data develops, it is IgG which will eventually be used to predict immunity and protection, if longer term immunity is found to occur for SARS-CoV-2."
Since the IgG serological response is potentially long-lasting the evaluation of an IgG antibody response appears well suited for the purpose of population screening to assess the burden of infections and possibly to evaluate incidence and the efficacy of prevention measures."
How often should I test someone for SARS-CoV-2 IgG?
There is currently no recommendation or guidance on the test frequency. Decision to test should be based on symptoms and contact tracing to a recently infected patient.
If someone is tested positive for SARS-CoV-2 IgG, does that mean he/she is immune to the virus now?
We do not know yet if having antibodies to the virus can protect someone from getting infected with the virus again, or how long that protection might last. Currently there is not enough information yet to say whether someone will be immune and protected from reinfection if someone has antibodies to the virus.
Is there a vaccine available for SARS CoV-2?
World Health Organization (WHO) is coordinating efforts to develop vaccines and medicines to prevent and treat COVID-19.
