Introduction:
A urine routine test, also known as a urinalysis, is a diagnostic laboratory test that is used to investigate the presence of abnormalities in the urine. The test is used to identify the presence of bacteria, blood, pus cells, and other substances in the urine. In this blog post, we will discuss the principle, uses, procedure, observation, and microscopy of the urine routine test.
A urinalysis is a test of your urine. It’s used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes.
Principle of the Urine Routine Test:
The principle of the urine routine test is based on the visual and chemical examination of the urine to identify the presence of abnormalities. The urine sample is collected from the patient and examined for its color, clarity, and odor. The sample is also tested for the presence of glucose, protein, and ketones. The test also involves the microscopic examination of the urine to identify the presence of bacteria, blood cells, and other substances.
Uses of the Urine Routine Test:
The urine routine test is used for a variety of purposes, including:
- To diagnose urinary tract infections.
- To monitor the effectiveness of treatment for urinary tract disorders.
- To screen for kidney disease.
- To detect early signs of diabetes.
Procedure of the Urine Routine Test:
The procedure of the urine routine test involves the following steps:
- Collection of Urine Sample: A urine sample is collected from the patient in a sterile container.
- Visual Examination: The sample is examined for its color, clarity, and odor.
- Chemical Examination: The sample is tested for the presence of glucose, protein, and ketones.
- Microscopic Examination: The sample is examined under a microscope to identify the presence of bacteria, blood cells, and other substances.
How you prepare before the test?
If you’re having only a urinalysis, you can eat and drink before the test. If you’re having other tests, you might need to fast before the test. Your health care provider will give you specific instructions.
Many drugs, including nonprescription medications and supplements, can affect the results of a urinalysis. Before a urinalysis, tell your doctor about medications, vitamins or other supplements you take.
Observation of the Urine Routine Test:
The observation of the urine routine test involves the following:
- Color: Normal urine color is yellow. Abnormal colors include red, brown, and cloudy.
- Clarity: Normal urine clarity is clear. Abnormal clarity includes cloudy and turbid.
- Odor: Normal urine odor is slightly unpleasant. Abnormal odors include foul-smelling and sweet-smelling.
- Glucose: The presence of glucose in the urine may indicate diabetes.
- Protein: The presence of protein in the urine may indicate kidney disease.
- Ketones: The presence of ketones in the urine may indicate uncontrolled diabetes.
- Blood: The presence of blood in the urine may indicate urinary tract infections or kidney disease.
Microscopy of the Urine Routine Test:
Microscopy of the urine routine test involves the following:
- Wet Mount: Wet mount is used to identify the presence of bacteria and yeast cells.
- Urine Culture: Urine culture is used to identify the presence of bacteria in the urine.
What does urine routine test show?
It’s used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes. A urinalysis involves checking the appearance, concentration and content of urine. For example, a urinary tract infection can make urine look cloudy instead of clear.
Results:
For a urinalysis, your urine sample is evaluated in three ways: visual exam, dipstick test and microscopic exam.
Visual exam
A lab technician examines the urine’s appearance. Urine is typically clear. Cloudiness or an unusual odor can indicate a problem, such as an infection. Protein in urine can make it appear foamy.
Blood in the urine can make it look red or brown. Urine color can be influenced by what you’ve just eaten or by certain drugs you’re taking. For example, beets or rhubarb might tint your urine red.
Dipstick test
A dipstick — a thin, plastic stick with strips of chemicals on it — is placed in the urine. The chemical strips change color if certain substances are present or if their levels are above typical levels. A dipstick test checks for:
- Acidity (pH). The pH level indicates the amount of acid in urine. The pH level might indicate a kidney or urinary tract disorder.
- Concentration. A measure of concentration shows how concentrated the particles are in your urine. A higher than normal concentration often is a result of not drinking enough fluids.
- Protein. Low levels of protein in urine are typical. Small increases in protein in urine usually aren’t a cause for concern, but larger amounts might indicate a kidney problem.
- Sugar. The amount of sugar (glucose) in urine is typically too low to be detected. Any detection of sugar on this test usually calls for follow-up testing for diabetes.
- Ketones. As with sugar, any amount of ketones detected in your urine could be a sign of diabetes and requires follow-up testing.
- Bilirubin. Bilirubin is a product of red blood cell breakdown. Usually, bilirubin is carried in the blood and passes into your liver, where it’s removed and becomes part of bile. Bilirubin in your urine might indicate liver damage or disease.
- Evidence of infection. Either nitrites or leukocyte esterase — a product of white blood cells — in your urine might indicate a urinary tract infection.
- Blood. Blood in your urine requires additional testing. It may be a sign of kidney damage, infection, kidney or bladder stones, kidney or bladder cancer, or blood disorders.
Microscopic exam
Sometimes performed as part of a urinalysis, this test involves viewing drops of concentrated urine — urine that’s been spun in a machine — under a microscope. If any of the following levels are above average, you might need more tests:
- White blood cells (leukocytes) might be a sign of an infection.
- Red blood cells (erythrocytes) might be a sign of kidney disease, a blood disorder or another underlying medical condition, such as bladder cancer.
- Bacteria, yeast or parasites can indicate an infection.
- Casts — tube-shaped proteins — can be a result of kidney disorders.
- Crystals that form from chemicals in urine might be a sign of kidney stones.
A urinalysis alone usually doesn’t provide a definite diagnosis. Depending on the reason your provider recommended this test, you might need follow-up for unusual results. Evaluation of the urinalysis results with other tests can help your provider determine next steps.
Getting standard test results from a urinalysis doesn’t guarantee that you’re not ill. It might be too early to detect disease or your urine could be too diluted. Tell your provider if you still have signs and symptoms.
