Diagnostic Tests & Procedures: Estimated Glomerular Filtration Rate

These flashcards cover key concepts related to the Estimated Glomerular Filtration Rate (eGFR) and its importance in assessing kidney health and chronic kidney disease.

Estimated Glomerular Filtration Rate (eGFR)

A calculation that estimates how well your kidneys are filtering waste and extra water from your blood.

Measured Glomerular Filtration Rate (mGFR)

A direct measurement of how well your kidneys are filtering substances not produced by your body.

Chronic Kidney Disease (CKD)

A condition characterized by the gradual loss of kidney function over time.

Creatinine

A waste product from normal muscle wear and tear that is an indicator of kidney health.

Cystatin C

A protein that slows down the breakdown of other protein cells, used as a marker to estimate kidney function.

Inulin

A type of fiber used in measuring kidney function; not produced by the body.

Iohexol

A contrast agent used in imaging tests that can assist in measuring kidney function.

Risk Factors for CKD

Conditions like diabetes, high blood pressure, obesity, being over age 60, and family history that can increase the likelihood of developing CKD.

Kidney Disease Stages

Five stages defining the severity of kidney disease based on eGFR levels, from normal function to kidney failure.

Normal eGFR Range

An eGFR of 90 or higher indicates normal kidney function.

Early-stage Kidney Disease eGFR Range

An eGFR of 60-89 may indicate early kidney disease.

Kidney Failure eGFR Range

An eGFR below 15 indicates kidney failure.

Symptoms of CKD

Urinating changes, itching, fatigue, swelling, muscle cramps, nausea, and loss of appetite.

Healthcare Professional

A practitioner who can order eGFR tests and interpret results for kidney health.

Nephrologist

A kidney specialist who manages kidney disease and its treatments.
