Cidney measures your Albumin-to-Creatinine Ratio (ACR) — the gold standard screening test for early kidney damage. It detects protein (albumin) in your urine and uses creatinine to confirm accuracy.

Cidney uses the same lab-grade colorimetric chemistry found in doctor's offices and clinical laboratories. It is CLIA Waived and FDA-recognized for over-the-counter use.

A lab ACR test requires a doctor visit, prescription, and 3–7 days for results. Cidney uses the same chemistry but gives you a screening result in 60 seconds at home.

Dip the strip in urine for 1–2 seconds, place pad-side up on a tissue, wait 60 seconds, then compare pad colors to the chart on the bottle.

First morning urine provides the most consistent results. Avoid testing after strenuous exercise, during a fever, or during a UTI, as these can cause false positives.

Retest in one week with first morning urine. If still abnormal, photograph your strip and consult your healthcare provider.
