Nej, det har kommit rapporter från Sydkorea om false negative provsvar i patienter som håller på och tillfrisknar. Vilket inte är speciellt konstigt, eftersom testen är kända för att bara vara tillförlitliga om man har symptom.
"South Korean officials on Friday reported 91 patients thought cleared of the new coronavirus had tested positive again. Jeong Eun-kyeong, director of the Korea Centers for Disease Control and Prevention, told a briefing that the virus may have been “reactivated” rather than the patients being re-infected.
The Geneva-based WHO, asked about the report from Seoul, told Reuters in a brief statement: “We are aware of these reports of individuals who have tested negative for COVID-19 using PCR (polymerase chain reaction) testing and then after some days testing positive again.
“We are closely liaising with our clinical experts and working hard to get more information on those individual cases. It is important to make sure that when samples are collected for testing on suspected patients, procedures are followed properly,” it said."
