Why pcr test take so long. “Behind every COVID-19 test sample is a person worried about their results”
The PCR data from every plate is analysed by two members of the team, to ensure consensus in judgement. These results are fed back into the software, which is equipped with artificial intelligence AI , thus enabling continuous improvement of diagnosis accuracy.
Finally, the anonymous test results are sent back to the NHS who will pass these onto their patients. Skip to main content. Twitter Facebook. Once through the doors of the Cambridge Testing Centre they will put on full PPE and stand in an air shower for 10 seconds, before stepping over the threshold into the lab. But what many of us may not know is how the process actually works. We meet the volunteers behind the testing, who explain how you go from swab sample to diagnosis.

Studies have suggested that PCR tests start to detect RNA from SARS-CoV-2, roughly days before the onset of symptoms — similar to when people start to become infectious — with the highest viral loads observed during the first few days of symptoms assuming the person is symptomatic.
From this point, the amount of virus gradually declines, until it can no longer be detected by PCR. In general, asymptomatic people may test positive for weeks, while those with mild-to moderate disease often continue to test positive for a week or more after this. Less sensitive lateral flow or rapid-antigen tests require a higher viral load to record a positive result, which is why they often only identify people during their most infectious period.
Even though PCR tests are widely regarded as the gold-standard for detecting SARS-CoV-2, they are not perfect, and their probability of detecting an infection will vary depending on when that test is performed. A PCR test done to confirm a coronavirus infection in someone who has recently developed COVIDlike symptoms, is more likely to detect the presence of viral RNA, than a test performed on someone who only became infected the day before, or who became infected several weeks ago.
However, studies performed under real-life conditions suggest false negatives may be more commonplace. In one recent study , Chinese researchers attempted to contact all close contacts of individuals who had tested positive for COVID, but who had tested negative themselves, and invited them to perform an antibody test. Despite these limitations to testing, the authors also noted that the overall control programme which included strict quarantine measures post-exposure was successful in controlling the spread of the virus.
They also highlight the importance of a multi-pronged control strategy, including quarantine measures for those exposed to the virus, and explain why many countries require travellers to conduct two PCR tests — one shortly before or after arrival, and another some days later, in case the first test misses the virus. A recent study published in The Lancet Microbe suggested that, in most people, there is no longer any live virus in the body nine days after the onset of symptoms — even though they may continue to shed viral RNA for weeks, or sometimes months after this.

Borderline results may indicate a very early infection or a prior infection with other Coronaviruses. It is recommended that the test be repeated at a pcg date.
