Creatinine, eGFR and uACR provide different but connected information about kidney health. Serum creatinine is a waste product measured in blood. It is used in an equation to estimate glomerular filtration rate, or eGFR. The uACR is a urine test that checks whether albumin is leaking through the kidney filters. In simple terms, eGFR estimates filtration while … Read more
Why Did My eGFR Drop Suddenly? Causes and What to Do Next A sudden drop in estimated glomerular filtration rate (eGFR) may happen because of dehydration, acute illness, reduced blood flow to the kidneys, a medication effect, urinary blockage, acute kidney injury, or normal biological and laboratory variation. Because eGFR is calculated mainly from blood creatinine, anything … Read more
A urine albumin-to-creatinine ratio (uACR) checks whether albumin, a blood protein, is leaking into your urine. In adults, a result below 30 mg/g is classified as A1, 30–299 mg/g as A2, and 300 mg/g or higher as A3. A high result can signal kidney damage, but one abnormal test does not by itself diagnose chronic kidney disease. It usually needs … Read more
