Recent blood tests done on me - CBC w/Differential/Platelet - show my red blood cell count is 5.35. Hemoglobin is 16.1. Hematrocrit is 48.3. I take B-12 injections ev. other week because my entire ilium was removed and 1/2 colon due to Crohn s Disease in remission since 1979. Reason was that I needed iron injected since I could not absorb it. Have been taking these injections since 1985 with no problems. These CBC numbers have been heightened a little since that time anyway & my GE doc said it is to be expected. Now my new, younger GP says he s concerned about the numbers because it may show I need oxygen through supplemental therapy. I presently have Idiopathic Interstitial Pulmonary Disease, DX in 2012. My GP wants the CBC redrawn now. He thinks the numbers are too high. I don t. I also was DX with Peripheral Neuropathy in 2003 - I take Lyrica for that. Your thoughts for the doctor s concern?
