Symptoms of kidney dysfunction, including
fatigue, fluid retention, and changes in urination, may manifest before any
rise in Cystatin C levels, a protein detectable through a blood test. Cystatin
C serves as a marker for kidney function and aids in estimating the glomerular
filtration rate (GFR). Elevated Cystatin C levels can indicate reduced kidney
function. Monitoring Cystatin C levels is essential in assessing kidney health
and tracking kidney disease progression, assisting healthcare providers in making
informed decisions about treatment and management strategies.
