My rheumatologist ordered a 24 hour urine test along with bloodwork at my first visit. All my life it seems like I’ve had a trace amount of blood in my urine. I saw a urologist years ago and discovered I have kidney stones. I have never passed any, they just seem to be happy staying put. I think the rheumatologist felt like my numbers were bad for my age and my lifestyle so she was looking for other causes and she definitely found one. I also had a lot of UTI’s as a child if that factors into the grand scheme of things. 🤷🏼‍♀️
