Hi. You probably know that due to the surge in coronavirus cases in the United States, Quest Diagnostics laboratories are lagging behind in processing and reporting test results, and the lead time for Covid-19 tests for many patients takes from a few days to a week or longer. "We attribute this demand primarily to the rapid, ongoing spread of COVID-19 infections throughout the country, but especially in the southern, southwestern and western regions of the country." You can read this in the quest diagnostics reviews
https://quest-diagnostics.pissedconsumer.com/review.html. Quest Diagnostics Labs can now run up to 125,000 tests per day, roughly double its throughput compared to two months ago.
