I will be finishing CLS as well in 2015 but have worked for a number years as an unlicensed everyman in several labs and blood banks. My Dad is a laboratory director who got there on a B.S. alone (see Old Economy Steve meme) but he really hates it. The managers I've encountered have an alphabet soup of things that sound really mind numbing to me (quality management, Six Sigma, etc.). My former manager could put 26 letters after her name if she wanted to based on all the nonsense she went after but she stuck to MT(ASCP), SBB(ASCP), CQA. Molecular is apparently the future assuming FDA approval comes through but, while the theory and mechanisms behind it are cool, it's still just pressing "play" like any other automated assay. I was trained by a traveling tech. for GenProbe who had gotten HLA certification and he described some neat opportunities related to organ transplantation since molecular assays will continue to create finer HLA matches.
I am also interested in path. asst. but you have to really love grossing because that's it. I was an autopsy technician for the local medical examiner and while it's definitely cool at first, the scenery doesn't change much. It's been said that the "assistant" title brings with it doing everything that the physician doesn't want to do and while some pathologists love autopsy and specimen prep., the vast majority do not. They like to stay in slacks behind the scope. Personally, I think 70-90K for chop shop all day is pretty good but I'm not very mobile at the moment and there is no school within 700 miles of me. The downward pressures/race to the bottom in pathology may affect the outlook for PAs but probably not by much. Dead people are not bad to work with and you quickly get used to decomposition smells, puke, stool, old blood and the like. It can be very sad to see so many people come to unfortunate ends but the fascination is endless. We got a burned corpse that appeared to be a house fire victim until we found the hollow point bullet deep in his neck. There was another poor fellow who created a device for autoerotic asphyxiation. Naturally, something went wrong and the ME found the beginnings of a tumor in his kidney that might have been his near-term downfall anyway if he wasn't into Carradine-ing. You get a chance to explore pathology in ways you wouldn't otherwise be able to but that also means loving pathology.
Introversion does not work well at all for management. You have to gladhand, a**kiss and finesse your way through not only the senior management riding you like a mule but also your army of disgruntled staff. Meeting after meeting after meeting and work never ends. One Thanksgiving, my dad tried to take some days off and in the middle of dinner, some employee felt that she was not appreciated enough and caused a huge disruption in the lab that he had to go mediate. He had to work on budgets and reports through VPN access the whole time anyway so his attempt at time off was a wash really. But, he takes home 95K so you have to ask yourself what's important to you in life. Part of me hopes I fall in enough love with the lab to counteract the itchiness wanting to be a clinician of some stripe but we'll just have to see. I'm beefing up pre-req's before my clinical year just in case.
