Problem: Text: 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 (C 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 C 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 eC).

Question: is creatinine clearance and gfr the same thing?

OPTIONS:
- no
- yes
A: no

Previous Speakers have been minority leaders (when the majority party changes, as they are already the House party leader, and as the minority leader are usually their party's nominee for Speaker), or majority leaders (upon departure of the current Speaker in the majority party), assuming that the party leadership hierarchy is followed. In the past, other candidates have included chairpersons of influential standing committees.
