CertifiedLabsWhat is COVID RT-PCR Test?
The COVID-19 RT-PCR test is a laboratory-based diagnostic test that identifies the presence of SARS-CoV-2, the virus responsible for COVID-19. It is a molecular test that detects the virus’s RNA in a nasal or throat swab, helping confirm an active infection.
SARS-CoV-2 belongs to the Beta coronavirus genus and is a single-stranded RNA virus. It spreads through respiratory droplets, contaminated objects, and in some cases, aerosol transmission in enclosed areas. After entering the body, it binds to receptors in organs such as the lungs and heart, leading to infection. Symptoms range from mild (fever, cough, tiredness) to severe (breathing difficulty, pneumonia, organ failure), with older adults and those with pre-existing conditions at greater risk.
To perform the test, a sample is collected from the nose or throat and analysed in a laboratory to detect viral RNA. A positive result confirms an active infection, while a negative result suggests no detectable virus at the time of testing.
For those in Noida, at-home COVID-19 RT-PCR testing is a practical option, ensuring swift sample collection and timely reporting of results.
COVID -19 RT PCR Test Parameters
The COVID-19 RT-PCR test evaluates a single key parameter: the detection of SARS-CoV-2, the virus responsible for COVID-19.
It functions by identifying small RNA fragments of the virus in a sample collected from a person’s throat or nasal passage. The test uses polymerase chain reaction (PCR) technology to amplify the virus’s genetic material, making it easier to detect.
Several factors affect test accuracy, including the timing of sample collection after exposure and how well the sample is obtained. While RT-PCR is considered highly reliable, improper sample handling can lead to inaccurate results.
In hospitalised COVID-19 cases, additional tests are often required to monitor health status. A Complete Blood Count (CBC) and Comprehensive Metabolic Panel (CMP) help assess overall health, while markers like C-reactive protein (CRP), D-dimer, and ferritin indicate inflammation and clotting risks. Chest X-rays and CT scans may be performed to check for lung complications such as pneumonia in severe cases, though they may not always show early signs of infection.
COVID Test Preparation
Here’s what you need to know before taking a COVID-19 RT-PCR test at home:
Prerequisites : No fasting or specific preparation is necessary before the test.
Best Time to Get Tested: The test is suitable for any time of the day.
Who Should Get a COVID RTPCR Test?: Those with symptoms such as fever, cough, or breathing difficulties, individuals who have been in close contact with an infected person, and those arriving from high-risk locations should consider taking the test for early diagnosis and prevention.
Cautions Before Taking a COVID RTPCR Test: No special precautions are required before undergoing the test.
Why Take the COVID -19 RT PCR Test?
The COVID-19 RT-PCR test is suitable for individuals in the following instances:
People Showing Symptoms: Fever, cough, difficulty breathing, extreme tiredness, sore throat, muscle pain, nausea, headache, or diarrhoea.
Individuals at Increased Risk:
Those living or working in shared spaces like dormitories and camps.
Recent travellers from areas with a high number of COVID-19 cases.
Medical professionals exposed to COVID-19 patients.
Severe Cases Needing Urgent Care:
Individuals with a serious lung infection requiring hospitalisation.
Those with a high fever (above 38°C) and breathing difficulties.
Testing helps in early detection, preventing the virus from spreading and ensuring timely medical treatment.
FAQs on COVID -19 RT PCR Test in Noida

Yes, Orange Health Labs provides a home sample collection service for COVID RTPCR testing. A certified eMedic will arrive within 60 minutes of booking to safely collect the sample.
A COVID RTPCR test detects SARS-CoV-2 by identifying viral RNA in a sample taken from the nose or throat, confirming infection in both symptomatic and asymptomatic individuals.
No fasting is required before this test.
The primary parameter assessed in a COVID RTPCR test is the presence of SARS-CoV-2 RNA in respiratory specimens.
The COVID RTPCR test determines infection based on Ct values. A result is positive when the Ct value is less than 40. Lower values indicate a significant viral presence, while higher values suggest reduced viral load.
COVID RTPCR test reports are generated within 57 hours following the collection of your sample.
Testing frequency for COVID RTPCR is determined by personal risk, symptoms, and a doctor’s evaluation.
