KIDNEY & LIVER
Estimated Glomerular Filtration Rate
Also known as eGFR
What it is
eGFR is a calculated estimate of how well the kidneys filter blood, based on creatinine, age, and sex.
Why it matters
eGFR is the standard measure of kidney function. It determines medication choices and safety for many therapies.
Range GPLX watches for
GPLX watches for eGFR above 60 mL/min/1.73m² as a general threshold. Values below that warrant further evaluation.
This educational range is not a personal diagnostic threshold. Your physician interprets your result in context of your full biomarker panel, medications, symptoms, and history.
What abnormal values can suggest
If low
A low eGFR value can suggest chronic kidney disease, acute kidney injury, or dehydration.
If high
A high eGFR value is generally favorable but can be artifactually elevated in low muscle mass.
