I am 42 years old. A history of high blood pressure for 2-3 years, now controlled on medication. Just had an ultrasound of the kidneys and found to have moderate bilateral cortical thinning. Recent labs revealed an eGFR of 52. I viewed labs back from 2008 and the eGFR was 70. The last three results in the past 2 months have been 57, 56 and now 52. Urine albumin is 48 and the urine creatinine is 390.1. There is no blood in my urine on spot check. Normal HgB A1c. No history of diabetes. Hemoglobin 14.7, hematocrit 44, and creatinine 1.14. Do I have CKD? Should I be seeing a nephrologist? My family physician has taken no interest in any of this inofrmation and disregards my questions. Please advise! Thank you!
