The percentage of transferrin carrying iron — the functional iron marker paired with ferritin in CKD.
TSAT = serum iron / total iron-binding capacity × 100. Low TSAT (< 20%) with appropriate ferritin signals iron deficiency needing supplementation before or alongside ESA therapy. High ferritin with low TSAT suggests functional iron deficiency or inflammation.
An iron-storage protein — the iron marker tracked with TSAT to guide anemia treatment in CKD.
Low hemoglobin caused by kidney failure — reduced erythropoietin production, iron deficiency, and inflammation — treated with iron and ESAs.
Iron given by infusion to treat iron-deficiency anemia in CKD — safer and more effective than oral iron in advanced stages.
A synthetic erythropoietin (epoetin alfa, darbepoetin) used to treat anemia of kidney disease.
