A compact kidney-testing device developed at BITS Pilani Hyderabad could bring key blood results closer to patients instead of sending every sample through a central laboratory. The portable, internet-enabled platform measures creatinine, urea and uric acid from a small serum sample and displays readings on a phone, tablet or computer. It may shorten the wait for an initial kidney-health assessment, although it is not yet a replacement for complete testing or a doctor’s diagnosis.
What Did The BITS Hyderabad Team Build?
Researchers from the campus’s MEMS, Microfluidics and Nanoelectronics Lab created a portable electrochemical platform for three renal biomarkers. Their study, “Dual-Interface IoT-Enabled Portable Electrochemical Platform for Multiplexed Detection of Renal Biomarkers,” appears in Electrochimica Acta.
The device uses laser-induced graphene electrodes, enzyme-based sensing layers and a miniaturised potentiostat. A serum sample goes onto a sensing chip, where separate electrodes read the three biomarkers. Software then converts the signals into concentration figures and shows them on a web dashboard.
Key features reported so far include:
- Simultaneous measurement of creatinine, urea and uric acid
- Results displayed on smartphones, tablets or computers
- Compact hardware designed for point-of-care use
- Testing with spiked and clinically obtained human serum
- Wireless transfer through an IoT-enabled system
Larger trials must still show how accurately the device performs across different patients and healthcare settings.
How Could Instant Kidney Tests Reduce Waiting Times?
Conventional kidney testing can involve blood collection, labelling, transport, processing, analyser time and report verification. In a rural clinic linked to a distant laboratory, those steps may turn a basic test into an hours-long or next-day process. The BITS Hyderabad kidney test device could remove several links by analysing the sample near the patient.
That could help primary health centres, emergency teams, dialysis units and telemedicine services make quicker referral decisions. A clinician could see an abnormal reading during the visit instead of waiting for a later report.
Still, “instant” needs context. The platform displays sensor readings quickly after a prepared serum sample reaches the chip. It does not remove blood collection, sample handling, medical interpretation, or confirmatory testing. Detailed reporting on the BITS Hyderabad prototype describes it as a system being developed for decentralised monitoring, not a device already available in clinics.
An Instagram news post covering the kidney-testing innovation also highlights its promise for faster screening.
Why Faster Kidney Screening Is Drawing Attention
Kidney disease can progress quietly, and early-stage patients may feel normal. The World Health Organization’s kidney disease fact sheet says an estimated 674 million people globally have chronic kidney disease, with many living in low- and middle-income countries. WHO also says serum creatinine and urine albumin tests can support detection in primary care.
India faces an access gap too. Long travel and limited diagnostic infrastructure can delay testing. Chronic kidney disease is covered under India’s non-communicable disease programme. Government data showed more than 40 crore screenings each for hypertension and diabetes by February 2026, creating a large group that may need kidney checks when risks appear.
A portable device could fit into that screening network, particularly where a full biochemistry analyser is unavailable. It may help a health worker decide whether a patient should be referred to a larger hospital.
What Must Happen Before Patients Can Use The Device?
The promising part is speed and portability. The unfinished part is clinical adoption. Researchers need wider validation against standard laboratory analysers, repeatability checks, shelf-life studies and safe sample-handling procedures. Manufacturing quality, data security and dependable connectivity will also shape deployment.
Regulatory approval is another major step. A kidney result can influence medicine doses, admission and dialysis decisions, so an inaccurate reading carries risk. Doctors also diagnose chronic kidney disease using more than three biomarkers. The NIDDK guidance on kidney testing identifies estimated glomerular filtration rate and urine albumin as core checks, often supported by repeat testing and clinical history.
The BITS Hyderabad device could reduce diagnostic waiting times for an initial assessment, especially outside major cities. Its impact depends on whether clinical trials confirm reliable results at scale and whether the final product stays affordable. For now, it remains a strong research prototype, not a home-testing shortcut or substitute for a nephrologist.
Frequently Asked Questions
1. What does the BITS Hyderabad kidney device test?
It measures creatinine, urea and uric acid together using a small prepared blood serum sample.
2. Does the device provide results instantly?
It displays readings within minutes, but collection, preparation and medical review still require additional time.
3. Can patients use this kidney device at home?
Not currently; the prototype requires further clinical validation, regulatory clearance and trained sample handling procedures.
4. Will it replace regular kidney function tests?
No, doctors may still require eGFR, urine albumin, repeat tests and other clinical examinations too.
5. Who could benefit most from this technology?
Rural clinics, primary health centres, dialysis units and patients needing frequent kidney monitoring could benefit.
