At-home kidney function tests check markers like creatinine, eGFR, and urine albumin to screen how well your kidneys filter – often before symptoms appear.
What they screen for
Kidney kits typically measure creatinine (to estimate eGFR) and urine albumin (ACR), the early warning sign of kidney stress.
Who should consider testing
People with diabetes, high blood pressure, or a family history of kidney disease benefit most, since kidney disease is often silent.
How it works
You provide a fingerstick blood sample and/or a urine sample and mail it to a certified lab.
