The Science behind Covid-19 Test in Delhi


The Science behind Covid-19 Test in Delhi

The novel Coronavirus has been stretched for over a year now, and with each passing day, there are several insights about the virus that are brought to light. While every nation is outlining initiatives to fight the virus, advancing various safety measures such as social distancing, using face masks, using hand sanitisers have been made compulsory. Hygiene volumes have been the top priority in every household, clinical laboratories, hospitals,  and also shopping centres.  

The statistics state that there have been 637,087 cases registered in the national capital of India, out of which 624,866 have been successfully recovered, with 10,899 deaths. There are 1041 active cases currently undergoing treatment. www.lalchandanipathlab.com/ helps identify the status of infection accurately.  

To determine the intensity of the virus, every individual was directed to take a COVID-19 test, irrespective of whether the person had symptoms or no. According to the World Health Organization (WHO), in most situations, a molecular test is considered to detect SARS-COV-2 and confirm the infection. Polymerase Chain Reaction (PCR) is a primarily used molecular test, conducted by collecting the nasal swab. To detect the levels of the on-going Coronavirus, three types of tests are essential for accurate results:

  1. RT-PCR Test: Real-time reverse transcription-polymerase chain reaction is one of the widely used laboratory techniques for detecting the intensity of the Coronavirus. Corona is an RNA virus, which infiltrates a healthy cell to multiply and survive. Therefore, RT-PCR test is used to identify the SARS-COV-2 RNA. The RNA is then converted to DNA through the reverse transcription process for detecting the intensity of the virus. 

  2. Rapid- Antigen Test: Antigen tests are used to diagnose the respiratory virus. Rapid- Antigen tests are used as a tool for quick results, antigen tests provide less accurate results. The test is conducted by collecting nasal swabs and placing them inside the antigen tool that detects foreign substances in the body of an infected person. A laboratory is not necessary to conduct the test, rapid antigen tests can be conducted at home too. This test requires nearly 15 mins to provide the result

  3. Serology Test: Also known as Antibody tests, Antibodies are specific proteins, produced by the immune system to prevent the body from viral attack. If there are more than enough antibodies present in a person’s blood, the blood plasma can be used to treat others. An antibody substance is present in the body of a person who has been tested negative for SARS-COV-2.

Why do we require testing?

Not everyone who is infected may have symptoms, and hence, to determine, and

  • To limit the spread of COVID-19.

  • To identify whether you are the infected individual and prevent a person to person transmission.  

Hence, it is essential to know that not all results will be accurate, testing in established laboratories is important to be close to accurate results. Dr Lalchandani Laboratory provides all three tests and has the most accurate result rate.  Stay Home & Be safe!
