Overview of the Creatinine (Urine)
The Creatinine (Urine) test measures creatinine excreted into urine.
The test contains 1 biomarker: Creatinine (Urine).
Creatinine is generated continuously through normal muscle metabolism, enters the blood and is subsequently filtered and excreted by the kidneys.
Urinary Creatinine can be used in several clinical contexts.
When measured within a timed collection, it can contribute to Creatinine Clearance calculations and assessment of total daily creatinine excretion.
Urinary Creatinine is also frequently used when another urine biomarker is expressed as a ratio to Creatinine.
Albumin/Creatinine Ratio and Protein/Creatinine Ratio are examples.
This helps adjust the other marker for how concentrated or dilute the urine specimen is.
A random urine Creatinine concentration varies significantly according to hydration and should not generally be interpreted as an independent measure of kidney filtration.
The required collection method should therefore be followed carefully.
What Does the Creatinine (Urine) Test Check?
This test measures 1 biomarker.
Creatinine (Urine)
Measures creatinine excreted in urine and can support timed renal calculations or interpretation of other urinary biomarkers.
Who May Benefit From the Creatinine (Urine) Test?
Urine Creatinine is generally most useful as part of another renal or metabolic investigation.
People completing a timed urine investigation - Creatinine can help interpret a 24-hour urine collection.
People undergoing Creatinine Clearance testing - Urinary Creatinine is required for calculation of clearance.
People having another urinary marker expressed relative to Creatinine - Ratios can adjust for variations in urine concentration.
People with a previous unusual urinary Creatinine result - Repeat testing may clarify the finding.
People undergoing kidney assessment - Urinary Creatinine can provide complementary information alongside blood tests.
People having a 24-hour urine collection assessed for completeness - Total Creatinine excretion can help determine whether a timed collection appears plausible.
People undertaking specialist metabolic urine testing - Several urinary analytes are interpreted relative to Creatinine.
People specifically advised to obtain urine Creatinine - The test can be arranged when the individual measurement is required.
How to Prepare
Do not deliberately alter your water intake to change the concentration of the urine.
If a significant portion of a timed urine collection is missed, contact London Blood Tests before submitting the specimen.
Symptoms and Reasons to Consider the Creatinine (Urine) Test
Urine Creatinine itself does not have a characteristic symptom pattern. Testing is usually requested because another renal or urinary investigation requires it.
A previous abnormal kidney-function result - Urine measurements may provide complementary information during renal assessment.
Protein detected in the urine - Creatinine can be used to calculate a Protein/Creatinine Ratio.
Albumin detected in the urine - Urinary Creatinine is used in the Albumin/Creatinine Ratio.
Known kidney disease requiring urine monitoring - Urinary markers can provide information that blood Creatinine alone does not capture.
Need for a Creatinine Clearance calculation - Timed urinary Creatinine is an essential component of the calculation.
A timed urine collection requiring assessment of completeness - Total Creatinine excretion can help evaluate whether the collection appears plausible.
Very dilute or concentrated urine results - Urinary Creatinine can provide useful context about specimen concentration.
Specialist metabolic urine testing - Other analytes may be normalised to Creatinine to improve interpretation.
These reasons do not mean that an abnormal urine Creatinine result alone diagnoses kidney disease.
Urinary Creatinine is generally interpreted as part of a ratio, timed collection or wider renal assessment.
How to Book Your Creatinine (Urine) Test

When Will I Receive My Results?
The current expected turnaround time is approximately 6 days after an acceptable specimen reaches the laboratory.
Incorrect or incomplete timed collection information may delay the result.
Understanding Your Results
Urinary Creatinine concentration depends strongly on how dilute or concentrated the urine is.
A low concentration can occur when urine is very dilute.
A higher concentration can occur in a more concentrated specimen.
For timed collections, total Creatinine excretion provides different information from the concentration of one sample.
Creatinine production is also influenced by muscle mass.
A standalone urine Creatinine result should therefore not be interpreted in the same way as serum Creatinine or eGFR.
It becomes more clinically useful when incorporated into Creatinine Clearance or another urine ratio.
