The widely used antigen rapid tests of pharmaceutical company Abbott are, according to Leiden researchers, a lot less reliable than expected, reports the WE Friday. According to the Leiden University Medical Center (LUMC) it appears research (pdf) that the test misses about 40 percent of positive infections.
Abbott’s rapid antigen tests were used 4,000 times at various GGD locations on Thursday alone. As with the normal PCR test, where a result is known after 24 hours, the Abbotts Panbio test takes moisture from the nose with a cotton swab. The test then checks whether a virus protein is present. The results will follow after fifteen minutes.
Abbott contradicts the WE the criticism of the LUMC and states that his test is “proven and accurate”. The American manufacturer is talking about an accuracy of 90 percent, but this is not found, according to the Leiden researchers.
The fact that the LUMC will publish the results on Christmas Day has to do with the holidays, according to researcher Frits Rosendaal, professor of epidemiology. “We discovered this the day before yesterday. We are concerned that people will feel safe after a negative rapid test and are going to celebrate Christmas with family. It is not good that Abbott’s tests only detect 60 percent of the cases.”
The RIVM says at the WE to know that rapid tests have a lesser reliability compared to the regular PCR test. That is why, according to the institute, it is important to observe the corona rules – even with a negative test.
