&lt;p&gt;&lt;span style=&quot;color: #808080;&quot;&gt;Cystatin C, combined with Estimated Glomerular Filtration Rate (eGFR) derived from serum levels, provides a reliable measure for assessing kidney function. Unlike traditional markers, cystatin C is less influenced by age, gender, or muscle mass, offering a more accurate estimation of glomerular filtration rate. This combined test is crucial in diagnosing and monitoring renal diseases and guiding treatment decisions for optimal kidney health.&lt;/span&gt;&lt;/p&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;

&lt;p&gt;&lt;span style=&quot;color: #808080;&quot;&gt;Evaluating renal function in individuals suspected of kidney disease, tracking treatment progress in those already diagnosed, and determining glomerular filtration rate (GFR) are essential tasks. This is especially critical in cases where serum creatinine might not accurately reflect kidney function, such as in very obese, elderly, or malnourished patients. Utilizing the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) cystatin C estimated GFR helps provide a more reliable assessment in such populations.&lt;/span&gt;&lt;/p&gt;
