I am a 59 year old, white female. I have been diagnosed with lupus, thalessemia minor, and I have a stent in my LAD. My blood pressure is low to normal and my cholesteriol is normal. I've been feeling tired. My doctor recently took blood and the results are generally normal except I have elevated Leukocyte esterase 1+ and WBC of 6-10. My Creatinine is 1.13 and eGFR Non-Afr American is 53. My Ferritin count is 342. In addition, my Hemoglobin is 10.2, Hematocrit is 32.7, MCV is 71.6. MCH is 22.5, MCHC 31.4 and RDW is 17.1. Some of these results are because of my diagnosed problems. But I am concerned about what I've read about these other tests are they indicators of some kidney disorder?
