Evidence-Based Kidney Health

About KidneyTracker

Making complex kidney health calm, understandable, and accessible for patients and caregivers, completely free.

Our Mission

An estimated 37 million American adults have chronic kidney disease (CKD), and approximately 90% of them are unaware of it. Because kidney disease often progresses silently without physical symptoms in its early stages, individuals can lose more than half of their filtration capacity before receiving a diagnosis.

KidneyTracker was founded to change this reality. We build free, evidence-based digital health tools and clinical directories that explain kidney function, lab results, dietary choices, and medication risks in plain, calm English. No subscription fees, no paywalls, no mandatory account sign-ups, and no personal data collection.

Our 4-Tier Clinical Review & Editorial Standards

Medical information online is too often either dense academic jargon or alarming worst-case scenarios designed to generate clicks. To provide reliable, trustworthy guidance for families managing serious health decisions, KidneyTracker adheres to four strict editorial pillars:

1. Primary Evidence Grounding

Every numeric range, lab cutoff, and clinical recommendation is verified against authoritative government agencies, clinical nephrology guidelines, and peer-reviewed medical literature. We do not publish unverified claims, anecdotal opinions, or commercial wellness trends.

2. Deterministic, Verified Data

Our tools rely on deterministic, structured datasets rather than generative approximations. Nutritional data is mapped to exact gram weights from USDA FoodData Central. Medication guidance reflects official FDA prescribing information and KDIGO clinical thresholds.

3. Patient-Centered Translation

We translate complex nephrology concepts (such as the 2021 CKD-EPI creatinine equation, active tubular secretion, and mineral bioavailability) into calm, scannable explanations. Our goal is to reduce patient anxiety and foster productive doctor-patient discussions.

4. Absolute Privacy Architecture

Health data belongs solely to the patient. All calculations (including eGFR scores, lab interpretations, and meal tracking) execute entirely inside your local browser via client-side code. Your medical values are never transmitted, collected, or stored on external servers.

Primary Clinical & Government Sources

KidneyTracker compiles and verifies its clinical datasets from the most respected nephrology and nutritional institutions in the world:

KDIGO (Kidney Disease: Improving Global Outcomes) Global non-profit organization developing evidence-based clinical practice guidelines for kidney disease staging, blood pressure targets, diabetes management, and glomerular diseases.
National Kidney Foundation (NKF / KDOQI) Leading kidney patient advocacy and clinical organization. We utilize NKF dietary benchmarks, potassium management protocols, and patient education standards.
USDA FoodData Central The United States Department of Agriculture agricultural research database. Powers our 300+ food directory with exact milligrams of potassium, phosphorus, sodium, and protein.
U.S. Food and Drug Administration (FDA / DailyMed) Official FDA drug labels, package inserts, and black box warnings used to verify eGFR dose adjustment thresholds, nephrotoxicity risks, and drug contraindications in our medication directory.
NIH / NIDDK (National Institute of Diabetes and Digestive and Kidney Diseases) Government research institute providing foundational clinical research on CKD epidemiology, diabetic kidney disease, and mineral bone disorder.
