Urine tests are the most frequent tests you'll receive. They're vital to detect any problems with the way your kidneys are functioning. Your physician will collect a urine sample and check for levels of protein (also referred to as proteinuria) and blood (hematuria) in the urine. Your protein levels should stay below 0.5 grams per day.
It's recommended that people living with lupus get a urine test every 3 months, while those with active lupus nephritis are tested as often as monthly.
