Disclaimer: Never stop treatment without medical advice.

In 30 Seconds

GFR estimates the kidneys' ability to filter blood. Chronic kidney disease is defined by a renal abnormality persisting ≥ 3 months, including GFR < 60 mL/min/1.73 m².

Why Does GFR Decrease?

  • Age (progressive decline possible)
  • Hypertension, diabetes
  • Dehydration / medications (to discuss medically)
  • Specific kidney conditions

The 2 Prevention Pillars

  1. Controlled blood pressure
  2. Controlled blood sugar (HbA1c, fasting glucose)

Simple Actions

  • Measure blood pressure at home if needed (reliable, regular)
  • Physical activity and weight loss if overweight
  • Review with doctor medications "at risk for kidneys" if GFR is low

FAQ

### Normal creatinine = kidneys OK? Not always: creatinine depends on muscle mass. GFR is more interpretable.

### How do I import my lab results into BioSense? It's very simple. Once you receive the email from your laboratory, download your report in PDF format. On BioSense, click 'Send my report' and import the file. Our technology automatically analyzes the data to provide you with a clear summary.

### Does BioSense work with all laboratories? Yes, BioSense is compatible with all Medical Biology Laboratories (LBM) operating worldwide. Whether you had your blood test done at a large national network or an independent laboratory, you just need to send us the original PDF.

### Is my health data secure during import? Security is our absolute priority. Your data is hosted on secure servers in Europe, compliant with GDPR standards. BioSense uses complete encryption to ensure your information remains strictly private and confidential.

### What if my report is on paper and not in PDF? For optimal analysis with BioSense, we recommend using the digital PDF file provided by your laboratory on its patient portal. If you only have a paper version, you can scan it cleanly to PDF using your smartphone before importing.
