  • Doctor, your study looked at both cystatin C and creatinine for estimating glomerular filtration rates. (aacc.org)
  • And then if we just sort of look across all of the patients, if you use the combined equation it sort of averages all this out so that if you didn't know what kind of patients you have that probably the safest as far as bias at least would be to use the combined creatinine-cystatin C equation. (aacc.org)
  • Well certainly creatinine and cystatin C, they both work to measure GFR because they are freely filtered and then they also have a relatively constant rate of production so that at a given steady state the blood level will reflect what your kidney function is. (aacc.org)
  • The AACC/NKF document also recommends incorporating a marker called cystatin C into eGFR equations in addition to creatinine, because equations that use both markers show superior performance over those that use one or the other. (newswise.com)
  • The researchers looked at two new eGFR formulas that do not include a race adjustment: one used creatinine alone - the standard test - and the second looked at both creatinine and cystatin, a newer blood test that is thought to improve accuracy when kidney function is at higher ranges. (scienceblog.com)
  • When they looked at the eGFR creatinine-cystatin formula, they found that among 289 Black patients, kidney failure was reached at an average 21 months, versus an average 26 months for 152 white patients, which was also not statistically significantly different, but more divergent than the results of the eGFR creatinine formula. (scienceblog.com)
  • These findings suggest that the new creatinine-cystatin equation, but not the creatine equation, is still associated with differences in pre-emptive wait time by race," said Ku. (scienceblog.com)
