State-of-the-Art GHC-SCW Labs

GHC-SCW labs use state-of-the-art technology to bring you accurate and timely diagnostic services. We are proud to be certified by the CMS CLIA Certification of Compliance. 

What to Expect When You Need Tests

  • Your primary care provider or specialist will tell you that you need tests done in the lab.
  • For some tests, you might not be able to eat or drink anything except water for 12 hours. Those tests are usually done right away in the morning.
  • You don’t need an appointment, except for some tests at Madison College Community Clinic.
  • You’ll come to the lab, sign in and you’ll be called back when it’s your turn.
  • You’ll be served on a first come, first served basis. The typical wait time is around 15 minutes.
