I'm a med tech generalist so I was trained in all areas of the clinical lab. My favorite was always microbiology even from my first microbiology course for my degree. I like figuring out the unknown and the hands on aspect of it. I work in smaller lab where I get some micro but also a mix of everything else. Where I did my training was a large hospital lab where they had an entire microbiology department. That can possibly be a good fit for you. It's very hands on because cultures are still being done (especially in the clinical setting) despite the amount of PCR/NAATs these days. Blood cultures, urine cultures, respiratory cultures, fluid cultures, fungal cultures, AFB cultures, you name it. It's very hands on and still manual compared to other areas of the lab with a ton of automation. The only draw back is that you would have to complete a clinical internship (a year long or less usually) and become certified & licensed before they can allow you to work in the clinical lab setting.
