Studies on efficacy of HCQ for COVID-19 must employ zinc+hydroxychloroquine+azythromycin to maximize the value of the study (zinc is what ultimately kills the virus), and to be fair, the therapy must be administered upon the presentation of COVID-19 symptoms or suspicion of COVID. Tests are unreliable enough to make it a not so hot idea to depend on test results to make treatment decisions, since waiting a couple days for a result is time that the COVID19 patient may not have, and a false negative test could wind up costing an elderly or high risk patient their life.
One doctor who was COVID positive, tested negative 5 times, before he tested positive.This is a doctor that started treatment upon suspicion of symptoms, which is the way perhaps thousands of doctors all around the world, are treating this disease.
Note when this doctor began treatment on frail elderly (COVID positive) patients in a nursing home environment - as soon as there was a slight reduction in blood oxygen.
