On the job training for MT or ASCP for Microbiologist?

You'll need to contact any college with a medical technology program. They have contracts with various hospitals that offer the clinical internships. You'll probably need to enroll in the college while doing the internship. I got my degree in biology/chemistry before my internship started, so I had to stay enrolled at my school during my internship year, giving me an additional 32 hours of college credit. No accredited teaching lab is going to let you do on-the-job training informally - they will require you to be enrolled in an MT program at a college.

Response to comments:

Most likely what you are seeing are ads from large reference laboratories, such as Roche, Quest, or LabCorps. There is a nationwide shortage of medical technologists, so some labs will hire someone without the clinical rotation experience. If you have the appropriate college degree and you have at least one year's experience in any particular section of the laboratory, you will become eligibile to sit for an ASCP registry, but, if you pass, you will certified to work in just that one area of the laboratory. A person who graduates from a medical technology program and takes the registry examination, is certified to work in all areas of the laboratory. For instance, I am a medical technlogist (MT) through ASCP so I could legally work anywhere in a laboratory as an MT, but if your experience was in chemistry, for instance, then you would be certified as a chemist (C) through ASCP. There is a big difference. It wouldn't matter if you weren't certified in all areas of the laboratory if you worked in a very large lab, because your employer could just leave you in the one department during your entire employment. However, if you wanted to change jobs, then you would have to find a laboratory that needed a chemist and only a chemist.

If you can afford to go to school for another year, I highly recommend doing the formal internship at an accredited school of medical technology so you can sit for the MT(ASCP) registry. You'll have far more career options if you do.

I recommend you go to www.ascp.org where you can read in depth the various routes to registry.

Good luck to you.
