AI Summary A urinalysis is a simple urine test that checks for signs of infection, kidney problems, diabetes, and liver disease. It has three parts: a chemical dipstick, a visual exam, and a microscopic exam. Bilirubin in urine may point to the liver, while protein and blood more often point to the kidneys or urinary tract. It does not diagnose liver disease alone. Doctors read it with blood tests. Call your doctor if dark urine lasts longer than one day.

A urinalysis checks a sample of your urine for color, clearness, and chemicals. It needs no needle or scan. Doctors use it to look for early signs of several health problems, including liver disease.
This page explains how the test works, what common findings may mean, and when to call your doctor. It also links to detailed guides on bilirubin, urobilinogen, protein, and ketones.
A urinalysis does not diagnose liver disease on its own. Your care team reads it together with your symptoms, blood tests, and imaging.

Urine test basics
A urinalysis is a simple test that checks your urine (pee) for signs of health problems. Doctors use it to look for infections, kidney problems, diabetes, and liver disease. It can find some diseases early, when treatment works better.
For liver care, the urinalysis is a supporting test. Bilirubin in urine may point to the liver. Most other findings, such as protein or blood, point more often to the kidneys or urinary tract.
That is why doctors read a urinalysis alongside blood work such as liver function tests. Together, the results give a fuller picture than any single test.
This group has four detailed guides: bilirubin, urobilinogen, protein, and ketones.
How the test works
Each part looks for something different. Your lab may report one, two, or all three.
A thin plastic stick with chemical strips is dipped into a recently produced urine sample. A strip changes color when a substance is above normal. The dipstick can check acidity (pH), protein, glucose (sugar), white blood cells, bilirubin, and blood.
The lab looks at the color and clearness of your urine. Blood can make urine look red or the color of tea or cola. Infection can make it look cloudy. Foamy urine can be a sign of kidney problems. Dark brown, clear urine can point to extra bilirubin, which is linked to liver disease.
A small amount of urine is viewed under a microscope. This finds things you cannot see by eye: red blood cells, white blood cells, bacteria, and crystals. Crystals form from chemicals in urine and can grow into kidney stones over time.
Common urine test results
These are common patterns. A single result rarely gives the full answer.
| Finding | What it is | What it may suggest |
|---|---|---|
| Bilirubin | A waste product from the breakdown of old red blood cells, normally removed by the liver | May be a sign of liver disease |
| Protein | A building block that belongs in your blood, not your urine | Suggests the kidney's filtering units may be damaged |
| Glucose (sugar) | A sugar that normally stays in the blood | Usually a sign of diabetes |
| White blood cells | Also called pus cells | A sign of infection |
| Blood | Red blood cells in the urine | Can point to infection, a kidney problem, certain medicines, or heavy exercise; needs further testing |
| Acidity (pH) | A measure of acid in the urine | Above normal may suggest kidney stones, urinary infections, or kidney problems |
| Ketones | Chemicals checked in urine or blood, mainly in people with diabetes | Testing can show whether type 1 diabetes has led to ketoacidosis |
Food colorings, supplements, and dehydration can make urine look darker for a short time. Blood in urine can also come from certain medicines or heavy exercise. Your doctor will decide which results need follow-up.
Detailed urine test guides
Bilirubin and urobilinogen are the two chemicals most tied to the liver. Protein and ketones help your care team check the kidneys and diabetes.
Bilirubin in urine may be a sign of liver disease. Your doctor may compare it with the bilirubin level in your blood.
Urobilinogen is another urine chemical your care team may review alongside bilirubin. The guide explains how to read it in context.
Protein in urine suggests the kidney's filtering units may be damaged. Kidney health matters in liver care, because advanced cirrhosis can lead to kidney injury.
Ketone testing is used mainly to check whether type 1 diabetes has led to ketoacidosis. It can be done on urine or blood.

Common Questions
No. A urinalysis checks for signs of several problems, including infection, kidney problems, diabetes, and liver disease. Bilirubin in urine may be a sign of liver disease, but your doctor confirms a diagnosis with blood tests, imaging, and sometimes other exams.
Bilirubin in urine may be a sign of liver disease. Bilirubin is a waste product from old red blood cells, and a healthy liver normally removes it from the blood. Your doctor will look at your blood bilirubin and other liver tests to find the cause.
Not always. Dark urine linked to liver disease is usually consistently dark brown and clear, not cloudy, because of extra bilirubin. Food colorings, supplements, and dehydration can also darken urine for a short time. If it lasts longer than one day or comes and goes, speak with your provider.
Blood in urine needs further testing, but it does not mean you have a serious medical problem. Infection, a kidney problem, certain medicines, or even heavy exercise can cause it. Your doctor will decide which tests come next.
A dipstick is dipped into a recently produced urine sample. The lab also checks color and clearness and may look at the sample under a microscope. Ask your care team if they have special instructions for collecting your sample.
