Creatinine- vs. cystatin C-based equations compared with 99mTcDTPA scintigraphy to assess glomerular filtration rate in chronic kidney disease.

Conclusions: At GFR <60 ml/min, CKD-EPI and Hoek equations appeared to best correlate with 99mTcDTPA. In controls and at early stages of CKD, creatinine-based equations correlated better with 99mTc-DTPA, with CKD-EPI being the one with the best degree of agreement.
