A Renal Function Measure is an organ function measure that assesses kidney function and filtration capacity (supporting renal health evaluation).
- AKA: Kidney Function Test, Renal Function Test, Kidney Function Measure, Nephrology Test.
- Context:
- It can typically assess Kidney Function through blood analysis.
- It can typically measure Filtration Rate through glomerular assessment.
- It can typically evaluate Excretory Function through waste measurement.
- It can typically monitor Renal Health through biomarker analysis.
- It can typically guide Treatment Decision through clinical parameter.
- ...
- It can often detect Kidney Disease through early marker.
- It can often track Disease Progression through sequential measurement.
- It can often adjust Medication Dosage through clearance calculation.
- It can often predict Clinical Outcome through prognostic indicator.
- ...
- It can range from being a Basic Screening Test to being an Advanced Diagnostic Measure, depending on its test complexity.
- It can range from being a Single Point Measurement to being a Continuous Monitoring Assessment, depending on its temporal scope.
- It can range from being a Direct Function Measure to being an Indirect Function Estimate, depending on its measurement approach.
- ...
- It can interact with Blood Chemistry for metabolite analysis.
- It can integrate with Urine Analysis for excretion assessment.
- It can coordinate with Imaging Study for structural evaluation.
- ...
- Examples:
- Filtration Measures, such as:
- Glomerular Function Tests, such as:
- Clearance Tests, such as:
- Blood Markers, such as:
- Serum Analysises, such as:
- Protein Markers, such as:
- Urine Measures, such as:
- Protein Analysises, such as:
- Electrolyte Tests, such as:
- ...
- Filtration Measures, such as:
- Counter-Examples:
- Liver Function Measure, which assesses hepatic function rather than renal function.
- Cardiac Function Measure, which evaluates heart performance rather than kidney performance.
- Lung Function Measure, which measures respiratory capacity rather than filtration capacity.

- Renal function, in nephrology, is an indication of the kidney's condition and its role in renal physiology. Glomerular filtration rate (GFR) describes the flow rate of filtered fluid through the kidney. Creatinine clearance rate (CCr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR. Creatinine clearance exceeds GFR due to creatinine secretion,which can be blocked by cimetidine. In alternative fashion, overestimation by older serum creatinine methods resulted in an underestimation of creatinine clearance, which provided a less biased estimate of GFR. Both GFR and CCr may be accurately calculated by comparative measurements of substances in the blood and urine, or estimated by formulas using just a blood test result (eGFR and eCCr). The results of these tests are used to assess the excretory function of the kidneys. Staging of chronic kidney disease is based on categories of GFR as well as albuminuria and cause of kidney disease.
Dosage of drugs that are excreted primarily via urine may need to be modified based on either GFR or creatinine clearance.
