eGFR has been erratic over the past year or so, ranging from 73 to over 100. Was 87 in September. As of May 5, it is 60--lowest ever. Have mild undifferentiated connective tissue disorder for which I take Plaqeunil, but no other problems, though blood pressure has gone from low in the fall to a bit elevated the last few times I have seen a doctor. What should my next step be? PCP said wait a month and retest eGFR. Also, was unable to produce a urine specimen that day, so they were unable to see if there was protein or blood in my urine. Sigh...so worried.
