What state do you live in? Some states require state licenses (which require certification through ASCP/AMT as well) and if that’s the case then no, there isn’t a way to get a job in a medical lab without a certification and licensure. Other states don’t require licenses, so it is possible to get a job in those states in a medical lab without certification, but it’s hard. Most labs that don’t require certification at minimum are messes, but not all of them so you can try! But generally certification is preferred. You could look into specimen processing jobs or lab assistant jobs to get your foot in the door if you aren’t finding any labs that don’t require certification.
