Relationship between serum EPO and mGFR. Mercadal et al7 studied the relationship between serum EPO and mGFR among anemic patients. They found that, as CKD progressed, the observed EPO response lagged well behind the expected response, indicating a relative deficiency of EPO. mGFR, measured glomerular filtration rate.
