Identifying kidney injury before conventional markers become abnormal

Chronic kidney disease progresses silently. RenoraDx is developing approaches to detect earlier biological signals of kidney stress—at a stage when intervention may still be meaningful.

The Challenge

Kidney disease progresses silently

Chronic kidney disease (CKD) is among the most prevalent non-communicable diseases globally, affecting an estimated 850 million people worldwide.1

Standard clinical markers—primarily serum creatinine and estimated glomerular filtration rate (eGFR)—lack sensitivity for early-stage injury. By the time these indicators fall outside normal range, substantial nephron loss may already have occurred.2

The majority of CKD cases go undiagnosed until late stages, limiting opportunities for meaningful clinical intervention.3

Earlier signals could change what is possible

Emerging research suggests that kidney injury generates detectable molecular signals prior to the functional decline captured by GFR-based testing.4 Novel biomarkers—including urinary and plasma proteins associated with tubular stress and glomerular injury—have shown potential to identify CKD progression at earlier stages than conventional assays.5

  • Earlier awareness may support more timely clinical decision-making
  • Could expand the window for disease-modifying strategies
  • Aligns with growing demand for precision diagnostics in nephrology
  • Addresses a known gap in the diagnostic landscape for high-risk populations

The hypothesis that earlier detection translates to better outcomes is supported by clinical data in adjacent disease areas,6 and is an active area of investigation in nephrology.

Disease Context

The CKD detection gap

Standard diagnostics are optimised for established disease, not early injury. This is the gap RenoraDx is working to address.

Stage 0–1
Subclinical kidney stress
Molecular-level changes begin. GFR remains normal. No clinical symptoms.
Target signal window
Stage 2–3a
Mild functional decline
GFR mildly reduced. Most patients remain undiagnosed. Intervention still viable.
Earlier detection zone
Stage 3b–4
Moderate-severe decline
Serum creatinine begins to rise. Conventional markers become abnormal.
Standard detection
Stage 5
Kidney failure
Dialysis or transplant required. Limited therapeutic options remain.
Late-stage presentation
Our Approach

A new approach to early detection

RenoraDx is developing a diagnostic approach aimed at identifying kidney stress earlier than conventional measures allow—without overstating what the science currently supports.

01

Novel biomarker identification

Targeting biological signals associated with early tubular and glomerular stress that precede measurable GFR decline. Grounded in published nephrology and proteomics research.

02

Diagnostic assay development

Translating biomarker candidates into a clinically actionable diagnostic format—designed with sensitivity for early-stage detection as the primary objective.

03

Clinical validation pathway

Pursuing rigorous validation through prospective cohort studies in collaboration with academic nephrology and clinical partners to establish diagnostic performance.

04

High-risk population focus

Initial focus on populations with known CKD risk factors—diabetes, hypertension, and cardiovascular disease—where earlier detection would have the greatest clinical value.
