A computer displays a positive COVID-19 sample Oct. 27 in IU’s COVID-19 testing labs in Myers Hall. If the curves from the testing sample pass a threshold, marked by the colored lines across the graph, the sample is positive, scientific director Craig Pikaard said. The sooner a curve crosses a threshold on the x-axis, the more virus is present in that sample. All positive and inconclusive results are double-checked by hand, Pikaard said. Colin Kulpa
