Simple Tests Can Detect Kidney Issues Early, Prevent Dialysis

As of November 18th, 2025, experts are emphasizing the importance of simple blood and urine tests in detecting kidney issues early and preventing the need for dialysis. According to Dr. Nikhil Bhasin, a consultant nephrologist, the serum creatinine test and estimated glomerular filtration rate (eGFR) are crucial indicators of how well the kidneys are filtering waste from the blood. Urine tests can also detect early signs of kidney disease, such as the presence of protein or blood.

While these basic tests are the first and most important step, imaging techniques like ultrasound or CT scans can also play a role. Dr. Mahesh Prasad, a senior consultant nephrologist, explains that imaging helps identify structural causes of kidney dysfunction, such as stones, blockages, scarring, or congenital abnormalities. However, he notes that imaging is not always the initial step, as it can appear normal even when kidney function is reduced.

Experts recommend that for individuals at risk, such as those with diabetes, hypertension, or a family history of kidney disease, regular blood and urine monitoring is crucial. Imaging should be used only when there are specific symptoms or abnormalities detected through the initial tests. Early detection through these simple measures can go a long way in preventing chronic kidney disease and the need for dialysis later on.
