I've written a small application to generate charts of my blood work. You may have noticed the "Cancer Statistics" link in the side bar. This used to contain 1 (relatively ugly) chart. I now have charts for White Cells, Red Cells, Hemoglobin, Neutrophils and Absolute Neutrophils. As soon as I have more PCR data, I'll add a chart for that as well. Each chart notes significant events and indicates a normal range for the reading.
Not to geek out on you (which means I'm going to) but it's interesting the story the charts tell. In particular note the Neutrophils and Absolute Neutrophils charts. The Neutrophils chart shows the percentage of white blood cells that are neutrophils. The Absolute Neutrophils chart shows the actual number of neutrophils. For instance, if the white cell count was 1000 and the neutrophil reading was 65%, the Absolute Neutrophils would be 650.
The percentage of white blood cells that were Neutrophils started out low (between May and mid June 2008). However, the actual number of Neutrophils (the Absolute Neutrophil count) was very high. Based on this we can tell that I had a very high number of abnormal white blood cells that weren't neutrophils. This caused the percentage of neutrophils to be low, but the absolute count to be high. This means I had so many junk white cells that even though the actual number of neutrophils was very high, there were relatively few compared to the overall white cell count.
The application I wrote makes it easy to update and publish these charts so they should stay up to date each time my blood is drawn.
