Factors that affect interpretation of nutritional markers in CKD

Fluid status: altered body composition and biochemical markers
Systemic inflammation: increased (hsCRP) or decreased (albumin, prealbumin, cholesterol) acute phase protein synthesis
Proteinuria: major determinant of serum albumin levels
Residual renal function: some biochemical markers, such as prealbumin, are cleared by the kidneys
  • hsCRP, high-sensitivity C-reactive protein.
