- People with diabetes, hypertension, cardiovascular disease or known kidney risk
- People with abnormal creatinine/eGFR or urine findings
- Anyone whose medication needs renal monitoring

TEST PASSPORT · REVIEWED JULY 2026
Kidney function + urine ACR
Use filtration and urine albumin together for a more complete kidney-risk view.Creatinine-based eGFR estimates filtration; urine albumin-to-creatinine ratio detects albumin leakage. Trends and persistence matter more than one isolated result.
ACCESSLab drawBlood + spot urine
TURNAROUNDOften 1–3 daysProvider and location dependent
RELATIVE COST$–$$Total downstream cost matters
COMMERCE STATUSPartner readyBlood + at-home urine collection pathway
HOW TO USE THIS PAGE
Decide whether this test deserves a place in your plan.
- 01Confirm the question
Be clear about what decision the result would change before ordering.
- 02Check fit and preparation
Review who it helps, who should pause and how to protect the quality of the signal.
- 03Plan the response
Know what you will do with a normal, abnormal or unclear result.
01 / WHO SHOULD TAKE IT
Fit the test to
the person.
Testing is useful when the result can change a real decision. These are educational selection criteria, not a diagnosis or personal order.- Interpreting creatinine without muscle mass, hydration and trend
- Diagnosing chronic kidney disease from a single transient result
02 / SIGNAL VS. STORY
What it tells you.
What it cannot.
01
Estimated filtration from blood creatinine
02
Urine albumin relative to creatinine
03
Risk category when values are persistent
01
eGFR is an estimate and can be affected by muscle mass and creatine intake
02
Exercise, infection and menstruation can transiently affect urine albumin
03
Chronic disease generally requires persistence or other evidence
03 / MARKERS + RANGES
Read the panel
without chasing flags.
The report should show its own method, units and laboratory reference interval. Clinical decision thresholds may be different from a lab interval. We do not invent a universal “optimal” range where authoritative guidance does not support one.Use the laboratory unit and method, then interpret with symptoms, trend and the decision this marker can change.

MEN, WOMEN + LIFE-STAGE CONTEXT
The correct range is personal context—not pink versus blue numbers.
Where biology differs, we call it out. Clinical interpretation should also reflect organs present, hormone therapy, pregnancy, age, medications and health history.
Pregnancy, menstruation and lower average muscle mass influence testing context; avoid urine contamination when possible.
Higher muscle mass can raise creatinine; urine ACR and sometimes cystatin C can clarify discordant cases.
04 / PREPARATION
Protect the quality
of the signal.
The best assay cannot rescue the wrong timing, wrong specimen or wrong question. Follow the ordering clinician and laboratory instructions when they differ from this general guide.Avoid unusually hard exercise before a baseline urine ACR when possible.
Use normal hydration; extremes can distort measurements.
Report creatine and high protein intake rather than assuming a creatinine change equals damage.
REPEAT CADENCEAt least risk-based for diabetes/hypertension and clinician-guided for abnormal or treated disease; confirmation is usually required.
05 / AFTER THE RESULT
Turn the number
into a next step.
- 01
Repeat transient abnormalities
- 02
Control blood pressure and glucose when relevant
- 03
Review medicines and kidney-protective treatment with a clinician
DO NOT WAIT ON A CONSUMER TEST
Rapid swelling, breathing difficulty or much less urine
Blood in urine, severe flank pain or confusion
