Hi Darryl. My HCT (hematocrit - may have spelled that wrong) was waaaay out of whack and high. I had blood testing last fall and they failed to do a complete blood count (CBC). That's the first indication that showed it and will for most people. I started with a new physician and she ran the full gammit of blood tests on me to get a baseline on my health when I started with her a couple months go. Bam. There it was. Associate yourself with a good medical system. My preious doctor ran tests on me but NOT a CBC. No idea how long I have had this.
