Propagation of measurement errors in glomerular filtration rate determination: a comparison of slope–intercept, single-sample and slope-only methods

Conclusion Measurement errors are probably insignificant relative to biological variation for GFR of more than 60 ml/min/1.73 m2, but become significant irrespective of biological variation at lower GFR, particularly in serial studies when GFR less than 25 ml/min/1.73 m2. Limits of precision recommended in the 2018 British Nuclear Medicine Society guideline are appropriate for once-off GFR measurement, whereas slightly more stringent limits are proposed for serial studies.
