In this study, only individuals with GFRs > 60 mL/min/1.73 m2
were evaluated. Previous studies have reported discordant findings
depending on serum creatinine levels: one found less interference
at high creatinine levels (mean, 3.02 [2.15–4.24] mg/dL) [11], whereas
another one showed significant underestimation of pre-dialysis
serum creatinine levels of patients receiving regular hemodialysis
[34]. In the latter study,
