Glomerular Filtration Rate (CKD-EPI)
The test assesses the kidney glomerular filtration rate (GFR) using the CKD-EPI formula, allowing determination of kidney function and detection of early stages of chronic kidney disease (CKD).
Mechanism of abnormalities: decreased GFR indicates worsening kidney filtration function. High values are rare and require physician assessment.
Recommended for:
- people with chronic kidney diseases
- with swelling or elevated blood pressure
- for monitoring kidney disease treatment
- with suspected decreased kidney function
Biomaterial: Venous blood
- Submit fasting (8-12 hours without food)
- Do not drink water
- Avoid alcohol and excessive physical exertion for 24 hours
- Avoid stress
Medications: if taking diuretics or kidney medications — inform the doctor
- Suspected decreased kidney function
- Chronic kidney diseases
- Swelling, elevated blood pressure
- Decreased urine volume
- Monitoring chronic kidney disease progression
Normal — GFR within reference values considering age, sex, and race
Decreased GFR — signals kidney function disorder
Which doctor to consult:
If kidney function disorder is suspected or test abnormalities are detected, consultation with a nephrologist is recommended. The doctor evaluates laboratory results, clarifies clinical symptoms, and if needed prescribes treatment or additional tests.
Self-treatment is not recommended!
