Walk-in lab services

We are the only medical lab in Humboldt County that’s open seven days a week, 8 am to 5 pm Monday – Friday and 8 am to 3 pm Saturday – Sunday, and no appointments needed for testing. Since we’re even open on weekends, stopping by to get your ordered lab tests is convenient and flexible.
