In recent weeks, Lancet has been put on the spot after some of those who went for Covid-19 tests at the facility tested positive and later tested negative at KEMRI. The most recent case involved 17 members of staff of St Andrew’s Turi who tested positive for Coronavirus but later tested negative when they went for a second test. Lancet CEO Dr Ahmed Kalebi on Wednesday set the record straight as he sought to explain the conflicting results among patients. Dr Kalebi stated that the tests conducted by Lancet are very specific and maintained that positive results are real. Through a newsletter seen by Ureport, Lancet added that false-negative results may occur in up to 20% of swabs done especially in mild or asymptomatic individuals.
