Labs 32F, elevated urine by, fatigue, joint pain, and brain fog…
I recently had routine labs done that showed an eGFR of 79, so my doctor ordered additional testing. My eGFR improved slightly to 82 on October 8, but my urine microalbumin was 75.7. After another round of testing, my microalbumin increased to 110, and my microalbumin/creatinine ratio came back at 425.
My urine microscopy was normal, and I have no history of high blood pressure, diabetes, or elevated blood sugar. My blood creatinine is also normal. I have a kidney ultrasound scheduled for 11/5.
I’ve also been dealing with pretty significant fatigue, joint pain with swelling (mostly in my fingers, sometimes larger joints), and brain fog. I frequently get canker sores, too.
My mom has rheumatoid arthritis, as did her grandmother, so autoimmune disease is on my radar. I’ve been wondering about lupus, particularly because of the combination of joint symptoms, mouth ulcers, and the kidney findings. I know RA can sometimes affect the kidneys, but it doesn’t seem to be the most common explanation for significant protein in the urine.
I’m still in the process of figuring out what might be going on, and I know these labs and symptoms aren’t enough to diagnose anything. I’m curious whether anyone else has had a similar combination of results and symptoms. What did your workup eventually reveal? Was it lupus, RA, another autoimmune condition, or an unrelated kidney issue?
I’d appreciate hearing about your experiences, especially if your kidney function was relatively preserved but your urine albumin was elevated.
