Renal Function

Renal function tests show how well your kidneys filter waste, balance fluids and minerals, and help control blood pressure and bone health. Because early kidney problems are often silent, routine blood and urine testing can find issues before symptoms start—especially if you have diabeteshigh blood pressure, heart disease, a family history of kidney failure, or a history of urinary problems or stones.

The Beta-2-Microglobulin (B2M) Test measures levels of B2M, a protein found on most cell surfaces and released into the blood. Elevated levels may indicate multiple myeloma, lymphoma, chronic infections, or kidney disease. Doctors order this test to evaluate cancer stage, prognosis, or kidney function. Results provide essential insight into disease progression, immune activity, and treatment monitoring for blood cancers and renal disorders.

The BUN Creatinine Ratio Test compares blood urea nitrogen (BUN) to creatinine levels to assess kidney function and hydration status. A high ratio may indicate dehydration, gastrointestinal bleeding, or high protein intake, while a low ratio can suggest liver disease or malnutrition. Doctors order this test with kidney panels to evaluate fatigue, swelling, or abnormal lab results. Results help diagnose renal issues and guide treatment planning.
