I've been diagnosed with Iron Deficiency Anemia. In July 2014 CBC was Hct 34 Hemoglobin 10.5 MCHC 31.0 MCV 79 Platelets 351 RBC 4.32 RDW 16.5 WBC 7.3. In November 2014 all numbers similar except Platelets were 440. January 2, 2015 all results were within normal range except RDW 21.2. My Dr has refered me to a hematologist. I've only been on iron meds since November 27, 2014. Why would she refer me to a specialist?
