I get blood screenings every year as part of my health package at work. I'mout of the normal range in seven or eight categories each year, the same categories. If your MD has seen the results, you're o.k. or he would have ordered more tests or made some diagnosis. Ranges are only average. Many of us are out of the ranges simply because our body chemistry is a little different. For example, my RBC and hematocrit are always below the range, yet I'm not anemic nor am I suffereing from any disease. I simply have lower amounts (not much lower, but out of the range). Get teted every year and compare results. Once you have a base line, greater deviations are easy to spot.
