“On Call Bio was very professional and was able to accommodate the urgency in the situation. They explained the services and was able to relieve my worries as they dealt with the insurance company. Other companies were unable to take the job or handle the job with efficiency to get the ball moving. Since I was needing the job done in a small window of time.”
