Laboratory hours of operation are split amongst six (6) Medical Laboratory Technicians.  The Lab is staffed from 6:00 am - 10:30 pm, Monday through Friday, and 6:00 am - 2:30 pm, Saturday and Sunday. In addition, a Lab tech is on-call for emergency response after hours. 

Any testing that cannot be performed in-house is sent to Quest Diagnostics, a reference lab in Seattle, Washington.  We receive our blood bank supplies from the American Red Cross out of Yakima.  Laboratory testing is vital in assisting providers in diagnosis, treatment and monitoring of patient disorders. Jeremy

We accept all patients that have a doctor’s order with a diagnosis code for blood draws.  Our lab techs will make sure the results are sent to your doctor when all testing is complete.  We are pleased to serve all our communities and help them with their needs.
