No worries on your part...Stupid and risk-taking on theirs, but you're good...It pretty much takes a blatant blood-to-blood (or anything that has frank blood on it, exposed to a break in the skin -like a tattoo needle used on someone else) to transmit it...Even people having Gorilla sex (sorry for the visual) have an extremely low chance of transmitting it...
Despite training with SOC's, there are still those health care people out there that think they don't need to follow them, and carelessly expose themselves and others...
As a Paramedic, and unfortunately the recipient of a dirty needle stick with hep C, I've become the world's most aware (paranoid?) person there is. I've given nurses and lab techs alike a piece of my mind when they've gone to draw blood and haven't worn gloves, and then tell them why I feel so strongly...the universal reaction is the look of surprise (the big "O" sign) because I don't look like a drug user and I'm not covered in tattoos...(The stigma that comes with having Hep C)... No, I don't think you're being OCD...I think your being aware...good for you...It sounds like you may have had a new lab tech because most wouldn't be ruffled by a bad blood draw...And, call the lab supervisor. They need to be aware if their techs need further education or "refreshing" on their technique.....
I've been out of touch from the medical field for so long but here are some general guidelines gleaned from memory.
1. Washing hands between each and every patient. (hardly ever done by most lab techs)
2. changing gloves between each and every patient. (even this gets skipped sometimes)
3. not using any unclean supplies (needles, alcohol wipes, cotton balls, etc) from one patient to another. You know that rubber band they put around your arm before they take your blood - ever see a bad stick when someone bleeds on that band? I have. Think they change that band? Or just give it a wipe with alcohol? Watch.)
4. not touching something potentially contaminated (like the sink faucet or the trash can) with something clean (like the gloves the tech just put on) prior to doing a procedure.
There's a lot more - thise just off the top of my head.
Most people taking your blood these days are just underpaid techs who think (rightly )that you won't be able to call them on breaks in technique.
Thanks for your comment. What is considered proper procedure?
If proper procedure is followed there should be no risk. With that said there are an amazingly large amount of incompetent and/or uncaring people in the medical field these days. I've observed , at my Veterans Administration hospital in Los Angeles, the lab technician draw blood from me and use the SAME SET of gloves on the very next patient. He was protecting himself with the gloves- but not the patients.
Keep your eyes open.
