Highlights

  • The recent coronavirus update says that numerous individuals with Covid 19 symptoms are testing negative
  • There are a few probable reasons, for example, mutation of the infection getting away from detection, quality of inspecting and testing, and viability of RT-PCR kits
  • Tests can turn out wrong at different stages, from incorrect sample collection and short capacity to faulty extraction. Some other reasons are mentioned down below. 

As India battles to cope with the uncommon demand for RT-PCR tests, reports propose that up to 20% of people with Covid 19 symptoms are testing negative. This pattern of bogus negative test results may deny genuine patients medical facility and basic care while allowing asymptomatic ones to spread the infection by moving around. 

People With Covid 19 symptoms Are Tested Negative

RT-PCR tests, considered the highest quality level in the determination of Covid-19, are not intended to be perfectly accurate. The base affectability( to detect Covid) reported by the Indian Council of Medical Research (ICMR) for approving an RT-PCR test is 95%. That implies that up to 5% false test results of covid are expected. Theoretically, four expansive elements decide the accuracy of coronavirus testing: 

  1. a load of viral in the individual, 
  2. the quality of test collection and preparing, 
  3. the adequacy of the test kit, 
  4. the benchmark for test understanding. 

Even though the RT-PCR test is a decent test, there might have been issues with how the swab is taken, regardless of whether it was deep enough during sample collection or if maybe the individual took the sample test after too long. And the infection was not in the upper respiratory part no longer, but the inflammation had gotten inside the lungs. The entirety of this can bring about a false RT-PCR test of an individual who has all the Covid 19 symptoms.  

Price Crash Of RT-PCR

In a single year, the cost of the RT-PCR kit tumbled from over Rs 1,100 to under Rs 40. Since import obligation exemption was removed in October 2020, most brands left the Indian market because of the extra 15% expense trouble. Various Indian brands, as well, have been declining to sell less than Rs 100. Many have discovered a devoted corporate customer base who wouldn’t fret paying some extra to guarantee quality. Some are also offering numerous PCR kits at various price levels. 

Conclusion

There have been countless cases where the individual has all of the Covid 19 symptoms, but the reports are negative when tested. There are a few probable reasons, for example, mutation of the infection getting away from detection, nature of examining and testing, and viability of RT-PCR kits. Tests can turn out wrong at different stages — from poor sample test collection and defective extraction.
