COVID-19 Update: Our lab is still open and accepting samples as usual until further notice.  Many employees are working fewer hours and staggering work times in order to maintain social distancing.  We hope to maintain the high level of service that we normally provide but there may be extended turnaround times during this worldwide corona virus pandemic that is affecting us all.  Stay safe.
