VOICED : El 30% de las pruebas diagnosticas del coronavirus arrojan falsos negativos

The video discusses the issue of false negatives in COVID-19 testing, highlighting that 3 out of 10 results can be false negatives. This is not due to test unreliability but often due to incorrect technique. The French Laboratory Union corroborates this, noting up to 30% false negatives in diagnosed patients. A case of a teenager who died after two negative tests is mentioned. The RT-PCR technique, which amplifies the virus's genetic material, is explained. Proper sample collection is crucial, requiring swabs to reach the upper pharynx or the back of the throat. Timing of the test is also critical, as virus presence varies with infection stages, potentially leading to incorrect results even with perfect technique.
