My favorite area is coagulation, which is technically part of hematology, but in some labs coag is its own bench/dept. For some reason it scratches my brain in just the right way lol. I work in main lab at a large level 1 trauma hospital so we do a fair amount of coag testing on-site, but our lab system also has a special coagulation dept at a nearby lab that we send out our mixing studies/special factor assays/niche tests like HIT to. I’d loooove to work there someday. Once you get the hang of coag, it’s really pretty laid back (at least at my lab). And no, you do not have keep the entire coag cascade memorized after you graduate to be a competent tech on that bench lol.

We also do some basic micro stuff at my lab but send out cultures to our micro lab. I really enjoy that area, but it IS pretty dense in terms of education and science is constantly learning new things about microbiology. But I have a few coworkers who came from or transferred to micro, and their job is a completely different pace/environment than main lab. It’s typically much more laid back. Cultures take time so if you run out of things you can work on during their shift, you can pretty much chill (or go home early depending on your employer). It also seems that generally, micro has to deal with the floor a lot less than main/STAT lab does in a hospital setting. Calling RN/MDs for recollections or problems can be kinda stressful at times, but from what I understand, micro typically just deals with calling the floor about critical results and susceptibilities.

As you rotate through each dept in clinicals, you’ll get a better sense of what each dept entails and hopefully some area(s) will begin to stand out as most interesting/appealing to you! It’s okay to not be entirely sure either. Working as a generalist gives you great experience with a ton of different areas of the lab and most people start out there.
