Service Description
Walk in or book online for your Kidney Health Screen: BUN Test in Tucson today. About This Test Blood urea nitrogen (BUN) measures the amount of nitrogen in the blood that comes from urea — a waste product formed when the liver breaks down protein. Healthy kidneys filter urea from the blood and excrete it in urine at a steady rate; when kidney function declines, BUN rises in the bloodstream. This test measures serum BUN and is frequently interpreted alongside creatinine to calculate the BUN/creatinine ratio, which helps distinguish kidney-related BUN elevation from dehydration or high protein intake. BUN is a fast, low-cost first-look kidney marker — useful for periodic monitoring or as a starting point when kidney function is in question, before ordering a full metabolic panel or eGFR. Who This Test Is For Anyone with symptoms of kidney dysfunction — swelling in the legs or ankles, changes in urination, fatigue, or unexplained nausea — who wants a quick initial kidney check. People managing chronic kidney disease, diabetes, or high blood pressure who need a simple, periodic kidney function marker between full CMP panels. Those who are dehydrated, have recently increased protein intake significantly, or are taking medications that affect the kidneys and want to check BUN levels. Anyone who wants a low-cost starting point before deciding whether a full comprehensive metabolic panel is warranted. What to Expect & Preparation Preparation: No special preparation needed. Avoid unusually high-protein meals the day before for the most stable reading, but fasting is not required. Your Lab Visit: A quick blood draw, about 15 minutes.
