Anemia in context of CRF usually correlates with the severity of Renal failure.Deficiency of erythropoietin is the primary cause of anemia in chronic renal failure.Anemia is responsible for several nonspecific symptoms in a patient with CRF.
Mechanisms implicated for Anemia in CKD are-
1. Relative deficiency of Erythropoeitin: Also called hematopoietin or hemopoietin, it is produced by the peritubular capillary endothelial cells in the …

Estimated values
A number of formulae have been devised to estimate GFR or Ccr values on the basis of serum creatinine levels.

Estimated creatinine clearance rate (eCCr) using Cockcroft-Gault formula
A commonly used surrogate marker for estimate of creatinine clearance is the Cockcroft-Gault formula, which in turn estimates GFR: It is named after the scientists who first published the formula, and it …
