Kidney tests estimate how well the kidneys filter and whether they are leaking protein. Creatinine-based eGFR is the standard, cystatin C gives a filtration estimate that is not skewed by muscle mass, and the urine albumin-to-creatinine ratio catches early kidney stress that blood tests miss. These tests are ordered by people with high blood pressure, diabetes or a family history of kidney disease, by heavy-training athletes and high-protein eaters whose creatinine runs high, and to monitor medications that are hard on the kidneys.

Low-molecular-weight protein used to assess kidney function and estimate glomerular filtration rate (eGFR), often more sensitive than creatinine.
Calculates estimated glomerular filtration rate using both creatinine and cystatin C, providing a more accurate assessment of kidney function than either…
