As a contractor we call in for testing quite a bit. Rarefied is great at taking down our information, setting up quick appointments, calling us when they’re on site if they have questions about what we need tested. I love the quick turnaround time with the phone call of the results of the testing. If insurance is involved they quickly change the billing to include the insurance carrier.
