What is Effective Renal Plasma Flow (ERPF)?
What is Effective Renal Plasma Flow (ERPF)?
The volume of plasma that flows through the kidneys per minute. It measures renal tubular function.
What is Glomerular Filtration Rate (GFR)?
What is Glomerular Filtration Rate (GFR)?
A test that measures how much plasma is filtered by your kidneys each minute. It measures glomerular function.
How is ERPF measured?
How is ERPF measured?
99mTc-mertiatide is commonly used to measure ERPF. It measures how efficiently the kidneys are filtering waste products from the blood.

Study Notes
Quantitative Renal Studies
- Evaluate tubular and glomerular function numerically.
- Useful for monitoring renal pathology progression.
- Methodologies include blood sampling for tracer clearance and camera-based methods for measuring tracer accumulation.
Effective Renal Plasma Flow (ERPF)
- Measures renal tubular function.
- Typically performed after administering 99mTc-mertiatide.
- Defines the plasma volume flowing through the kidneys per minute.
- Historically measured using PAH (a non-radioactive substance).
- Estimation methods involve imaging, computer data processing, and blood/urine sample collection.
- Normal values range from 500-600 ml/min, varying by age and sex.
Glomerular Filtration Rate (GFR)
- Measures GFR using 99mTc-pentetate, as its renal uptake is proportional to GFR.
- GFR calculation methods utilize single blood samples or imaging with computer data processing.
- Normal GFR is 125 mL/min, varying by age and sex.
