Tuot DS, Lin F, Shlipak MG, et al. Potential Impact of Prescribing Metformin According to eGFR Rather Than Serum Creatinine. Diabetes Care , vol. 38 no. 11 2059-2067; doi: 10.2337/dc15-0542 ...

Median baseline eGFR measured by Cockcroft-Gault was 89 mL/min/1.73 m² and 82 mL/min/1.73 m² with eGFR-CR-Cys. Average patient age was 66, 66% were female, and 83% were white.

The new race-free creatinine-cystatin C estimating equation underestimated measured GFR in Black adults by 0.1 and overestimated measured GFR in non-Black adults by 2.9. Related Content ...

Things get a little more complex from here. Your creatinine level can provide information about your kidney function, but it isn‘t the same thing as your GFR.

The more creatine you have, like a supplement, means it’s more likely you’ll have higher creatinine,” he says. The eGFR , or kidney function score, is based on the creatinine levels, he says.

Previously, the equations for eGFR had a race adjustment that meant Black patients had a higher eGFR despite having the same creatinine level. The rationale for this is based on earlier studies that ...

Using the eGFR creatinine formula, they found that among 350 Black patients, kidney failure was reached at an average 23 months, versus an average 22 months for 122 white patients, which the ...

The eGFR test is the most widely-used formula to calculate kidney function. It measures creatinine, a waste product of muscles, and factors in age, sex, weight - and race.

Metformin eligibility was examined among 3,902 adults with diabetes from the 1999 to 2010 National Health and Nutrition Examination Surveys using conventional sCr thresholds and eGFR categories.

Using the eGFR creatinine formula, they found that among 350 Black patients, kidney failure was reached at an average 23 months, versus an average 22 months for 122 white patients, which the ...
