The kidney's second number

What is urine albumin (UACR) and why test it?

A normal eGFR doesn't mean your kidneys are fine — many people have never had the second number, UACR, checked.

  1. 1UACR = urine albumin-to-creatinine ratio. One random urine sample is enough — no 24-hour collection.
  2. 2Categories: A1 <30 | A2 30–300 | A3 >300 mg/g.
  3. 3At the same eGFR, higher albuminuria means higher risk of kidney failure and cardiovascular events — the second axis of the KDIGO risk heat map.
  4. 4It can be changed: blood pressure and glucose control, and medicines such as RAS blockers and SGLT2 inhibitors — discuss with your doctor.
  5. 5If you have diabetes, hypertension or known CKD, guidelines advise testing at least yearly — more often at higher risk.

0–5Report: eGFR ticked normal, empty box "UACR ?"Normal eGFR — so the kidneys are fine? Not necessarily. There is a second number.
5–16Urine cup + "one random sample"UACR is the ratio of albumin to creatinine in urine. One random sample is enough — no all-day collection. It shows whether the kidney filter is leaking protein.
16–28Three bands A1 A2 A3Under 30 is A1, 30 to 300 is A2, over 300 is A3. The higher the number, the bigger the leak.
28–40KDIGO heat map: green → yellow → orange → redAt the same eGFR, more albuminuria means higher risk of kidney failure and heart disease. That is why guidelines grade eGFR and UACR together.
40–52BP monitor, glucose meter, pill boxThe good news: it can change. Blood pressure and sugar control, and certain kidney-protective medicines, can bring it down — talk to your doctor.
