Overview of the Microalbumin (Urine) Test
The Microalbumin (Urine) test measures small amounts of Albumin leaking into the urine, providing an early marker of kidney filtration damage.
The test assesses 1 renal biomarker: Microalbumin (Urine).
Albumin is a major blood protein that should normally remain within the circulation.
Healthy kidney glomeruli prevent significant quantities of Albumin from passing into urine.
When these microscopic filtering structures become damaged, small amounts of Albumin can begin to appear before routine kidney blood tests such as Creatinine or eGFR become abnormal.
This early increase was traditionally called microalbuminuria.
Current kidney terminology more often describes this as moderately increased Albuminuria.
The test is particularly relevant in people with diabetes, high blood pressure and other conditions associated with chronic kidney disease.
Albuminuria also carries cardiovascular significance because persistent urinary Albumin loss can reflect wider vascular and renal damage.
A single raised result does not automatically prove chronic kidney disease.
Urinary Albumin can temporarily increase after strenuous exercise, fever, urinary infection, acute illness or significant physiological stress.
Menstrual contamination can also affect a urine specimen.
For this reason, an unexpected abnormal result may need repeating.
A urine Albumin/Creatinine Ratio, or ACR, is often preferred for ongoing kidney-risk assessment because it corrects Albumin concentration for how dilute or concentrated the urine is.
Microalbumin measurement remains useful as a sensitive assessment of low-level urinary Albumin.
What Does the Microalbumin (Urine) Test Check?
The test measures small amounts of Albumin excreted into urine. This test measures 1 biomarker.
Microalbumin (Urine)
Measures low-level urinary Albumin leakage, supporting early detection and monitoring of kidney filtration damage.
Who May Benefit From the Microalbumin (Urine) Test?
Microalbumin testing can be useful when early kidney damage needs to be detected before symptoms or major blood-test abnormalities develop.
People with diabetes - Diabetes is an important cause of persistent Albuminuria and chronic kidney disease.
People with high blood pressure - Hypertension can damage the kidney's filtration system over time.
People with known chronic kidney disease - Urinary Albumin can provide additional information about renal damage.
People with cardiovascular disease - Albuminuria can be associated with increased cardiovascular and renal risk.
People with metabolic syndrome - Diabetes, hypertension and metabolic dysfunction can increase kidney risk.
People with a family history of kidney disease - Screening may be useful where other risk factors are present.
People with a previous raised urinary Albumin result - Repeat testing can establish whether Albuminuria persists.
People undergoing proactive kidney monitoring - Urinary Albumin can detect abnormalities before symptoms appear.
How to Prepare
Temporary Albuminuria can occur with exercise, fever, infection and acute illness.
Unexpected elevation may therefore need confirmation with repeat testing or a Urine Albumin/Creatinine Ratio.
Symptoms and Reasons to Consider the Microalbumin (Urine) Test
Early Albuminuria usually causes no symptoms.
Diabetes requiring routine kidney monitoring - Kidney damage can begin before eGFR falls.
Persistent high blood pressure - Hypertension can damage glomerular filtration.
A previous positive urine protein result - More sensitive Albumin measurement can provide additional information.
Known chronic kidney disease - Urinary Albumin can help characterise renal involvement.
Unexplained kidney-risk factors despite normal Creatinine - Early Albumin leakage can precede changes in blood kidney markers.
A previous abnormal Microalbumin result - Repeat testing can determine whether the finding was persistent or temporary.
Visible blood in urine, major swelling, very low urine output or rapidly worsening kidney function requires medical assessment.
One raised Microalbumin result should not be used alone to diagnose chronic kidney disease.

When Will I Receive My Results?
The current London Blood Tests turnaround for Microalbumin (Urine) is approximately 1–2 days after laboratory receipt.
The underlying laboratory assay can be processed rapidly once the specimen arrives.
Transport from the collection location occurs before the laboratory reporting period begins.
Understanding Your Results
A low result indicates little Albumin was detected in the urine specimen.
This is generally reassuring but should still be considered alongside blood kidney tests where kidney disease is being investigated.
A raised result indicates increased urinary Albumin leakage.
Possible causes include diabetes-related kidney damage, hypertension, glomerular kidney disease and other renal conditions.
Temporary elevation can occur after exercise, fever or infection.
The concentration can also be affected by urine dilution.
For ongoing kidney-risk assessment, ACR can provide a more standardised measurement because Albumin is compared with urinary Creatinine.
Persistent Albuminuria is more clinically meaningful than one isolated abnormal result.
Why Book With London Blood Tests?
London Blood Tests provides private Microalbumin testing for early kidney-health assessment.
Detects low-level urinary Albumin - The test can identify kidney filtration changes before substantial protein loss develops.
Relevant to diabetes monitoring - Albuminuria is an important marker of diabetic kidney involvement.
Useful in hypertension - High blood pressure can damage renal filtration.
Can detect abnormalities before eGFR falls - Early glomerular injury may appear first in urine.
Can complement ACR testing - Ratio-based testing can provide further standardisation where required.
Simple urine specimen - No blood draw is required for this individual test.
Fast laboratory turnaround - Results are expected approximately 1–2 days after laboratory receipt.
Clear pricing - The Microalbumin (Urine) test costs £99.
