They evaluate kidney function, detect signs of infection, and measure substances such as calcium and uric acid that may contribute to kidney stone formation.
Blood tests are an important part of the diagnostic evaluation for patients with suspected kidney stones. Although they cannot confirm the presence of a stone on their own, they help doctors understand how well the kidneys are functioning and whether any metabolic abnormalities are increasing the risk of stone formation.
Your urologist may recommend blood tests to assess the following:
Blood tests measure creatinine and blood urea nitrogen (BUN) levels to determine how well your kidneys are filtering waste products. If a kidney stone is blocking urine flow, kidney function may be affected.
High levels of calcium in the blood (hypercalcemia) can increase the risk of developing calcium-based kidney stones, which are the most common type of kidney stone.
Elevated uric acid levels may increase the likelihood of uric acid kidney stones. Identifying high uric acid early allows doctors to recommend dietary changes and medications to reduce future stone formation.
If you have fever, chills, or severe pain along with a suspected kidney stone, blood tests may show an increased white blood cell count, indicating an infection that requires prompt treatment.
For patients who experience recurrent kidney stones, blood tests help identify metabolic disorders that contribute to repeated stone formation. This information is valuable in creating a long-term prevention plan.
Blood tests are usually performed alongside urine analysis and imaging tests such as ultrasound or CT KUB scans to provide a complete assessment. Together, these investigations help your doctor confirm the diagnosis and choose the most appropriate treatment.
At SCI International Hospital, New Delhi, Dr. Gautam Banga, Senior Consultant Urologist and Andrologist, performs a comprehensive diagnostic evaluation for patients with kidney stones. Blood tests, urine analysis, and advanced imaging are used together to assess kidney health, identify the underlying cause of stone formation, and develop a personalized treatment and prevention plan. This evidence-based approach helps improve treatment outcomes while reducing the risk of future kidney stones.
