I have always had perfect bloodwork, I have a physical every year and my lab work always comes back perfect. Just had a CBC done back in Oct 2002 and six months later after a colonoscopy I end up with blood clots in my right arm, the docs say it was probably cause by the IV in my hand. Anyways I asked the dr after they were diagosed to run a CBC on me and my hemoglobin, RBCs and hematocrit were all just slightly elevated, just 7 tenths over the normal range. A week later he retook it and they had gone back into the normal range so I was relieved to say the least. Well I was feeling kind of tired and run down this weekend so they took my CBCs again and this time they where 4 tenths over the norm so I had another lab take them the next day and everything was normal but the hemoglobin, which was once again 4 tenths over. Has anyone had this happen after they had blood clots, can the blood clots elevate these blood components or could the warfarin elevate them slightly like this?? Again they are only slighty abnormal but still has me worried.
