Re: Smoking and CBC levels
I would think that if smoking affects your CBC and hemoglobin, it would also affect your ferriten test as well. After all, they are both testing your iron levels. Who knows... I've never heard of smoking increasing iron levels, but then again there are so many things out there that can skew labwork that it is possible that smoking can change things. One thing that can really mess with a CBC is hydration... if you're really dehydrated or too hydrated it can change things around. Food that you've recently eaten can also change things around. The amount of time the lab tech has the tournaquite (sp?) thing on can also skew numbers as well. However, the tournaquite would have to be on for a LONG time to affect things in a major way. Also, how the tubes of blood are handled can aslo affect the values. There are just SO many variables that can change things I wouldn't worry about it. Just about everyone who has had a CBC done has had their results skewed a bit due to external factors.
If smoking skewed lab values that much then most likely doctors would factor that into things. I'm not saying that doctors are all up on this stuff, they definitely are not, but if the values were off by a HUGE amount due to smoking then the medical community would take it into consideration. For right now it sounds like it might skew results by a bit but not enough to cause alarm or anything...... otherwise they might start asking people to not smoke the night before their labs are done, just like they do with fasting lab tests.... I wouldn't worry about it too much at all.
