Kidney Infection Diagnosis. The most important test in diagnosing kidney infection is a urinalysis (UA). This is basically a test to analyze urine sample and evaluate for an infection in the urine. Urinalysis is done by collecting a clean catch, midstream urine in a sterile collection cup. The urine may be analyzed by the doctor in the office using or by analysis in a laboratory. Because urine is normally sterile, any finding suggesting an infection may be considered abnormal and supportive of a kidney infection. 1  Gross inspection of urine (macroscopic analysis) may reveal cloudy urine.
Tests to check kidney function. When kidney function is decreased, substances such as urea, creatinine, and certain electrolytes begin to build up in the blood. The following tests measure levels of these substances to show how well your kidneys are working. The doctor can use the GFR to regularly check how well the kidneys are working and to stage your kidney disease. 2  A blood urea nitrogen (BUN) test measures how much nitrogen from the waste product urea is in your blood. 3  BUN level rises when the kidneys aren't working well enough to remove urea from the blood.
