What Is a Neutrophil Gelatinase-Associated Lipocalin (NGAL), Urine Test?
The neutrophil gelatinase-associated lipocalin (NGAL) urine test measures the level of a protein called 'neutrophil gelatinase-associated lipocalin' in a urine sample. This protein is released by kidney tubular cells (the cells lining the tiny filtering tubes inside the kidneys) when they are injured. It is primarily ordered when a doctor suspects early kidney damage. This test is also referred to as the NGAL urine test, the lipocalin-2 (LCN2) urine test, or the urinary neutrophil gelatinase-associated lipocalin test. A midstream urine sample is all that is needed for this test.
What Does a Neutrophil Gelatinase-Associated Lipocalin (NGAL), Urine Test Measure?
The neutrophil gelatinase-associated lipocalin (NGAL) urine test measures a single key protein in urine. The table below explains what it is and why it matters:
| Parameter | What It Measures | Why It Matters |
|---|---|---|
| Urine NGAL (Neutrophil Gelatinase-Associated Lipocalin) | A 25 kDa protein produced by injured kidney tubular cells | Rises sharply when kidney tubules are damaged, allowing detection of kidney injury earlier than traditional markers such as serum creatinine |
NGAL is normally present at low levels in urine. When kidney tubular cells are stressed or damaged, they release significantly more of this protein, making the NGAL urine test a sensitive early indicator of kidney injury.
Why Is a Neutrophil Gelatinase-Associated Lipocalin (NGAL), Urine Test Done?
A doctor may order this test in several clinical situations, from sudden illness to monitoring known kidney conditions.
Common Symptoms That May Require This Test
The following symptoms may prompt a doctor to request an NGAL urine test:
- Reduced or absent urine output
- Swelling in the legs, ankles, or feet
- Unusual fatigue or generalised weakness
- Nausea without a clear cause
- Shortness of breath
- Fluid retention in the body
- Confusion or difficulty concentrating
Conditions This Test Can Help Detect
This test can provide useful information for identifying or assessing the following conditions:
- Acute kidney injury (AKI), detected at an earlier stage than standard blood markers allow
- Intrinsic kidney damage, as distinct from reduced blood flow to the kidneys (prerenal AKI) or blockages downstream (postrenal AKI)
- Chronic kidney disease (CKD) and its progression over time
- Kidney injury caused by sepsis (a severe body-wide infection)
- Contrast-induced nephropathy, which is kidney damage that can follow certain imaging procedures using contrast dye
- Kidney transplant rejection
- Hepatorenal syndrome, a form of kidney dysfunction linked to liver disease, particularly cirrhosis
Neutrophil Gelatinase-Associated Lipocalin (NGAL), Urine Test for Chronic Disease Monitoring
The lipocalin-2 (LCN2) urine test has recognised value in patients already living with chronic kidney disease. It can help track changes in kidney tubular injury over time, giving clinicians early warning of deterioration. The test is also used for serial monitoring in patients receiving medicines that can harm the kidneys (nephrotoxic medications) or those undergoing repeated contrast imaging procedures.
How to Prepare and What to Expect
No special preparation is needed before giving a urine sample for this test. The process is simple and straightforward.
Do You Need to Fast?
No fasting is required before the NGAL urine test. You can eat and drink as normal before sample collection. If your doctor has ordered additional kidney or blood tests at the same time, ask whether any of those require fasting.
Practical Tips Before Your Test
The following steps will help you provide a clean, usable sample:
- A fresh morning urine sample is preferable where possible
- Inform your doctor about any medications you are currently taking, especially those that may affect kidney function
- Avoid contaminating the inside of the sample container
- Keep the collection container upright and ensure the lid is tightly secured
Step-by-Step Procedure
- Wash your hands thoroughly and clean the genital area before collection.
- Begin urinating, then collect the middle portion of the urine stream (midstream) in the sterile container provided by the laboratory.
- Close the container lid securely after collection.
- If the sample cannot be sent to the lab immediately, keep it refrigerated.
- Hand the sample to the phlebotomist or laboratory staff for prompt dispatch.
- Your result will be ready within the same day or up to 24 hours, depending on the laboratory.
Factors That Can Affect Accuracy
- Urinary tract infections (UTIs), which can cause false elevations in NGAL levels
- White blood cells in the urine (leukocyturia), a known cause of falsely high readings
- Systemic infections or widespread inflammation in the body
- Certain cancers, which can also raise NGAL levels
- Sample contamination during collection
- Delays between collection and laboratory processing
Understanding Your Neutrophil Gelatinase-Associated Lipocalin (NGAL), Urine Test Results
Your result should always be reviewed by your doctor, who will consider it alongside your symptoms, medical history, and other tests. The table below provides general reference ranges:
| NGAL Level (ng/mL) | Interpretation | Possible Condition |
|---|---|---|
| <150 (Normal Range) | No significant kidney injury | Normal renal function |
| 150–300 (Mild Elevation) | Early kidney stress or minor injury | Risk of Acute Kidney Injury (AKI), dehydration, mild nephrotoxicity |
| >300 (High Elevation) | Significant kidney injury | Acute Kidney Injury (AKI), contrast-induced nephropathy, sepsis-related kidney damage, drug toxicity |
| >600–1000 | Severe kidney injury | Advanced AKI, multi-organ dysfunction, high risk of progression to renal failure |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain health situations can alter your urinary neutrophil gelatinase-associated lipocalin test results in ways that are unrelated to kidney tubular injury. Urinary tract infections and the presence of white blood cells in the urine can raise NGAL levels, leading to readings that appear higher than expected. Bacterial infections and systemic inflammatory conditions (the body's widespread inflammatory response to illness or injury) can also push NGAL values upward, making results harder to interpret in patients with sepsis. Some cancer patients may also show elevated readings. Your doctor will consider all of these factors before drawing any conclusions.
How to Maintain Healthy Levels
The following general wellness habits support kidney health over time:
- Drink enough water daily to stay well hydrated and help your kidneys filter waste efficiently
- Keep underlying conditions such as diabetes and high blood pressure well managed, as both can affect kidney function over time
- Avoid taking medicines that can harm the kidneys without medical supervision, and always tell your doctor about every medicine or supplement you take

Frequently Asked Questions
The NGAL urine test is used to detect kidney tubular injury at an early stage, often before standard blood tests such as serum creatinine show any change. Doctors use it to assess the risk and severity of acute kidney injury, monitor chronic kidney disease, and evaluate kidney health in critically ill patients.
NGAL levels in urine can rise within 2 to 4 hours of kidney injury occurring. This is considerably earlier than creatinine, which may take 24 to 48 hours to reflect damage. This early rise makes the neutrophil gelatinase-associated lipocalin (NGAL) urine test particularly valuable in urgent or critical care settings.
Doctors typically order the neutrophil gelatinase-associated lipocalin (NGAL) urine test for patients who are critically ill, have had major surgery, or are at high risk of kidney injury due to sepsis, cirrhosis, or respiratory compromise. It may also be ordered for patients receiving medicines known to affect kidney function or those undergoing contrast imaging procedures.
No fasting is required. You can eat and drink normally before providing your urine sample. Simply follow the collection instructions provided by the laboratory to ensure the sample is clean and uncontaminated.
Yes. Urinary tract infections can cause NGAL levels to appear higher than they actually are. White blood cells in the urine, which are common during a UTI, are a known source of false elevations. Always inform your doctor if you have or suspect a UTI at the time of testing.
A high result may indicate kidney tubular injury, which can be caused by acute kidney injury, sepsis, contrast dye used in imaging, or nephrotoxic medicines. However, elevated levels can also occur due to infections or inflammation unrelated to the kidneys. Your doctor will review the result alongside other tests, such as serum creatinine and urine output, before drawing any conclusions.
Yes. For patients with chronic kidney disease or those on long-term medicines that may affect the kidneys, serial NGAL testing can help track changes in tubular health over time. Your doctor will advise whether repeat testing is appropriate in your situation.
