In the year 2020, if you were experiencing COVID-19 symptoms, you probably would have covered them up and been brave enough to go to a lab, doctor's office, or clinic to get a polymerase chain reaction (PCR) test. A medical professional would have stuck a swab up your nose, and you would have had to wait one or two days for the results. Now, you'd probably utilize a test that can be completed at home and provides findings in only 15 minutes. Even when tested against the newest models, it is simpler, faster, and trustworthy. The U.S. Food and Drug Administration estimates that at-home tests will successfully identify illnesses around 80% of the time, despite their limitations.
So is there any longer a need for a PCR test?
Several people appear to have come to the conclusion that there isn't based on the sharp decline in PCR testing rates. Over a year ago, the U.S. Centers for Disease Control and Prevention received weekly reports of more than 15 million laboratory test results. This amount has now decreased to around 2 million every week, and it's not only because there are fewer viruses in circulation. Research reveal that use of at-home tests has gradually increased over time, showing that many people are electing to test themselves instead of undergoing PCR tests. According to Dr. Charles Chiu, a professor of laboratory medicine at the University of California, San Francisco, an at-home test is a fantastic choice if you're feeling OK and simply performing your due diligence before traveling, socializing, or attending an appointment. Rapid tests can be useful if you have symptoms and wish to determine whether COVID-19 is the cause.
Nonetheless, a PCR test is still the best option occasionally, Chiu claims.
Since they are so sensitive and can pick up even minute amounts of COVID-19 genetic material, PCR tests are regarded as the gold standard of COVID-19 detection. After exposure, the SARS-CoV-2 virus takes some time to multiply in the body; typically, viral load peaks around the onset of symptoms. According to Dr. Chaz Langelier, an infectious disease specialist with the Infectious Diseases Society of America, a PCR test may be able to identify an infection even before that peak.
