eGFR

This laboratory investigation measures eGFR to help assess the relevant biochemical process, including aspects of kidney function, electrolyte balance, metabolism, or mineral status as applicable to the test. Clinicians use the result alongside symptoms, examination findings, medical history, medicines, and other laboratory measurements. Hydration, diet, treatment, and the timing of collection may influence some results. Follow any preparation instructions provided by the laboratory or clinician. An abnormal result does not by itself confirm a diagnosis and should be reviewed clinically.
