I'm a bit distressed, I am a confirmed non-smoker -- have never smoked, can't stand to be around cigarette smoke, and am not at all exposed to second-hand smoke, either at home or at work. However, after having blood drawn for my annual wellness test at work, I tested positive for high levels of cotinine. The test was repeated and the result was the same!
I've been doing a lot of research to see what could cause a false positive, and have read that certain foods in large quantities (almonds, mustard, broccoli, tomatoes, potatoes) could yield a false positive... but I've consumed none of those in large amounts.
Can anyone shed any light? I really don't want my medical file to look as if I smoke heavily, when I've spent my whole life avoiding cigarettes!! I do sometimes light candles in my house, could that have this affect?! Grasping at straws!View Thread
Annb46, I've read that cotinine passes from the body within a couple days of exposure, so you're definitely not seeing effects of any brief smoking you did 20 years ago.
Please let me know how you make out after the third test, and what kind of testing you do at the non-Quest lab! As you say, it is very frustrating to be portrayed as a smoker, so I'm wondering about potentially re-testing as well.View Thread
My company test was done at Quest Labs, which I have always believed to be a fairly reliable lab. My GP knows that I am a non-smoking athlete and feels like I should just put the whole thing out of my mind and not stress about it, but I hate having anything in my file that could portray me as a smoker, when I have been so adamantly anti-smoking for my entire life! Also, if there really IS nicotine in my body for some reason, might this be harmful in some way?
As Dr. Foulds suggested, I asked my GP about conducting an independent test, but she felt that urine and follicle testing were even less reliable than the bloodwork; in her opinion, I should just forget the whole thing. Still bothering me, though, and I unfortunately opted out of doing my company wellness testing this year, as I worried that the false result would be repeated!View Thread
Thanks for your response, Dr. Foulds. No! I've never used any nicotine replacement products because I've never smoked, and I've likewise never smoked pot as well! As a marathon runner, I train nearly every day and don't want any odd substances in my body, LOL.
I've washed my face with Noxzema every day since I was 13, and I know it contains menthol and camphor. I realize I'm just grasping at anything here, but could something like that cause a false positive?View Thread
