Kidney Function Test at Home: Early Detection of Kidney Disease with an Albumin Urine Test
A kidney function test at home detects albumin in your urine — one of the earliest signs of kidney damage. The Kidney Function Test from The Tester delivers 99% accurate results in just 5 minutes using a simple urine strip, helping you catch kidney problems before they become serious. No doctor’s appointment needed.
Why Kidney Health Matters More Than You Think
Your kidneys filter about 180 litres of blood every day, removing waste, balancing electrolytes, and regulating blood pressure. Chronic kidney disease (CKD) affects an estimated 10% of the global population — and most people don’t know they have it until significant damage has occurred.
The reason? Kidney disease is often called the “silent killer.” In early stages, there are virtually no symptoms. By the time you feel sick, you may have already lost 50% or more of your kidney function. That’s why early screening through a simple albumin urine test is so valuable.
What Does Albumin in Urine Mean?
Albumin is a protein that normally stays in your blood. Healthy kidneys filter waste while keeping proteins like albumin where they belong. When your kidneys are damaged, albumin leaks into your urine — a condition called albuminuria or microalbuminuria.
Even small amounts of albumin in urine can signal:
- Early-stage kidney disease
- Diabetic nephropathy (kidney damage from diabetes)
- Hypertensive kidney damage
- Increased cardiovascular risk
Who Should Test Their Kidney Function?
- People with diabetes — diabetes is the #1 cause of kidney disease
- Anyone with high blood pressure — hypertension damages kidney filters over time
- Those over 60 — kidney function naturally declines with age
- People with a family history of kidney disease
- Regular NSAID users — painkillers like ibuprofen can affect kidneys
- Anyone who is overweight or obese
- Smokers — smoking reduces blood flow to the kidneys

Signs of Kidney Problems to Watch For
While early kidney disease is silent, as it progresses you may notice:
- Foamy or bubbly urine (sign of protein)
- Swelling in feet, ankles, or around the eyes
- Frequent urination, especially at night
- Persistent fatigue and difficulty concentrating
- Decreased appetite or unexplained nausea
- Muscle cramps, especially at night
- Dry, itchy skin
If you notice any of these symptoms, testing your kidney function at home is a smart first step before visiting your doctor.

- Stay hydrated: Drink 1.5–2 litres of water daily
- Limit salt intake: Aim for less than 5g per day

Frequently Asked Questions
How reliable is a home kidney function test?
The Kidney Function Test from The Tester has 100% sensitivity and 98.04% specificity, meaning it catches virtually all cases of albuminuria with very few false positives. It’s CE-certified and manufactured to ISO 13485 standards.
When is the best time to take the test?
Use your first morning urine, as it is the most concentrated and provides the most accurate reading of albumin levels.
What should I do if my test is positive?
A positive result means albumin was detected in your urine. Consult your doctor for follow-up blood tests (creatinine, eGFR) and a comprehensive kidney health evaluation. Early detection allows for effective treatment.
How often should I screen my kidney function?
If you have diabetes or high blood pressure, test at least once a year. For general screening, every 1–2 years is recommended for adults over 40.
Can I test both my liver and kidneys at once?
Yes! The Liver & Kidney Function Combination Test checks both ALT/AST liver enzymes and kidney albumin in one convenient package.
Is albumin in urine always a sign of kidney disease?
Not always. Temporary albuminuria can occur after intense exercise, fever, dehydration, or urinary tract infection. If your first test is positive, it’s wise to retest after a few days and consult your doctor.
Do I need a prescription?
No. This is a CE-certified over-the-counter self-test available without a prescription.
