Early Detection Breakthrough: Study Identifies Blood Markers That Predict Kidney Risk in Diabetes Patients
India is facing a serious health crisis. With over 101 million adults suffering from Type 2 diabetes and nearly 136 million more living with prediabetes, the country’s healthcare system is under growing pressure. Diabetes doesn’t just affect blood sugar—it slowly harms organs like the kidneys, eyes, and nerves. Nearly one in three diabetic patients in India develops chronic kidney disease (CKD), which often goes unnoticed until it’s too late.
Traditional diagnostic tests like fasting glucose, HbA1c, and creatinine levels only show part of the picture. They fail to catch early biological changes that signal kidney risk years before symptoms appear. According to IIT Bombay researcher Sneha Rana, diabetes alters several metabolic pathways, not just glucose. Detecting these hidden changes early could help prevent life-threatening complications.
What the New Study Found
Researchers from IIT Bombay, Osmania Medical College, and Clarity Bio Systems Pune have made a promising discovery. Their study, published in the Journal of Proteome Research (July 2025), explored how tiny molecules in the blood—called metabolites—can reveal the real health of diabetic patients.
The team analyzed blood samples from 52 volunteers in Hyderabad. Using advanced techniques like LC-MS and GC-MS, they scanned nearly 300 metabolites. The results were eye-opening: 26 metabolites showed clear differences between healthy individuals and diabetics. Some expected ones like glucose and cholesterol were there, but several new ones—such as valerobetaine, ribothymidine, and fructosyl-pyroglutamate—had never been linked to diabetes before.
This means that diabetes is more than a sugar problem—it’s a deep metabolic imbalance. And spotting these changes early could help reduce kidney risk and other serious complications.

New Metabolic Markers for Kidney Risk
One of the biggest breakthroughs came when scientists compared diabetic patients with and without kidney problems. They found seven key metabolites, including arabitol, myo-inositol, and ribothymidine, that increased as the disease progressed. A compound called 2PY also rose steadily from healthy individuals to diabetic kidney patients.
These findings could help doctors identify patients who are at high kidney risk long before their kidneys show damage. “Monitoring these molecules could let us act early,” said lead author Sneha Rana. Dr. Manisha Sahay added that these markers might soon work alongside traditional kidney tests like creatinine and eGFR, giving doctors a clearer and faster way to intervene.
This approach could also guide treatment—some patients may need stronger medication, while others could benefit from targeted lifestyle changes.

Why This Study Matters for India
Unlike most international studies that analyze only plasma, this research examined whole blood, including red blood cells. This broader view may explain why some Western biomarkers, like branched-chain amino acids (BCAAs), didn’t show up in Indian patients. It also highlights the importance of developing diagnostic tools suited for the Indian population.
Professor Pramod Wangikar, who led the study, said the team is already working on a simple finger-prick blood test that could detect these metabolic markers from dried blood spots. If successful, this could revolutionize diabetes monitoring—especially in rural India, where access to advanced testing is limited.
This breakthrough could allow millions to manage their kidney risk early, before irreversible damage occurs.
What’s Next: Personalized Diabetes Care
The researchers plan to expand their study to include a larger group of patients from different regions. The ultimate goal is personalized diabetes care—where every patient gets treatment tailored to their metabolic profile.
In India, where most diabetes treatment still follows a one-size-fits-all model, this could be a game-changer. Detecting kidney risk through these blood markers means early prevention, fewer hospitalizations, and a better quality of life.
The study offers hope that one day, a simple test could tell you how close you are to developing kidney disease—and what steps you can take to stop it.
Latest Context
According to the World Health Organization (WHO), diabetes-related kidney disease is among the top ten causes of death globally. With India’s growing diabetic population, early testing methods like this study’s could save thousands of lives.
Health experts suggest maintaining a balanced diet, regular exercise, and routine medical checkups to reduce kidney risk. For people already living with diabetes, regular monitoring and doctor consultations remain the best line of defense.
