Can anyone tell me if a nicotine test would be done at a pre op for BA or on the morning of surgery?

This is not a routine test done before surgery. If your surgeon advised you to stop smoking, we generally trust our patients to be honest with themselves and us about important issues like smoking.

Many surgeons and facilities , including my practice, do test for nicotine preoperatively. This may be done routinely, or only in selective cases. Some procedures I will not perform if patients are still smoking, although augmentation is not one. Smokers are at higher risks for anesthetic complications, however. You should follow your surgeons guidlines on this, and tell them if you are currently smoking.

I routinely use the urine cotinine (nicotine) test prior to any procedure that includes resecting large amounts of tissue and skin and closure under tension (tummy tuck, breast reduction or lift, facelift). I usually perform this test at the patient's pre-op visit, which usually takes place two weeks prior to the procedure. I do not routinely perform this test for routine breast augmentation cases where I am making a small incision and not closing the incision under tension. I recommend checking with your board certified plastic surgeon regarding his or her specific protocol. Good luck with your procedure!
