Is there an easy, cheap way to know where blood levels are at?
My brother works as a long haul truck driver. His schedule is very unpredictable, so doctor's appointments are nearly impossible for him to get.
He needs transfusions every month or so, and wants to know when to get to a hospital before the whiteouts begin. Would blood pressure machines provide the information he needs? Are there more subtle signs to look for? Or is there some other simple way for him to test blood levels? Perhaps a machine he can buy?
He's been diagnosed with either ulcerative colitis or Crohn's Disease by doctors in three different states. None of them can pin down which of these he has, or stop the pain and bleeding. He *is* on medication.
