What we test for
Every Modern Checkup strip reads two markers in your urine — albumin and creatinine — and turns them into one number that shows how your kidneys are doing: your uACR. Here’s exactly what each pad measures, and what your number means.
One strip. Two test pads.
Inside is the same test chemistry Siemens makes for the machines in hospital labs. We put it on a strip you read at home — no lab, no appointment.
How to read the two pads
Read the albumin pad at 50 seconds
It sits nearest the handle. Colour change tells us how much albumin is leaking through.
Read the creatinine pad at 60 seconds
The outer pad. It tells us how concentrated the sample is, so hydration can be corrected for.
Two markers, one number
Here is exactly what each pad is measuring and why it earns its place on the strip.
A protein that belongs in your blood, not your urine. Healthy kidneys keep it in circulation. Stressed or damaged kidneys start letting it slip through — and that leak is the earliest measurable sign of kidney trouble, often years before you feel anything.
A steady waste product your muscles produce at a predictable rate. We read it alongside albumin to correct for how dilute your sample is — so a large glass of water before the test cannot flatter your result.
Albumin divided by creatinine — the urine albumin-to-creatinine ratio. It is the number kidney specialists, medical guidelines and your own past results can all be measured against. This is what we track for you, month after month.

What your number means
We sort your uACR into the same three levels a kidney specialist would use.
Under 30 mg/g
Normal to mildly increased
30 – 300 mg/g
Moderately increased
Over 300 mg/g
Severely increased
One reading is a snapshot, not a diagnosis.
uACR moves with exercise, illness and hydration. That is exactly why we test monthly — the trend is the signal, and a single number never is.
And what we don’t test for
We would rather be clear about the edges of this test than oversell it.
It doesn’t diagnose kidney disease.
Only a clinician can, using your history and a blood test. An abnormal result is a prompt to book that conversation.
It doesn’t measure blood sugar, cholesterol, or kidney filtering rate.
Those need a blood draw. Albumin in your urine is the sign that shows up first — often years before a filtering test would.
It doesn’t replace your annual physical.
It fills the eleven months in between, so nothing drifts unnoticed.
