What is urinalysis?
Uraline is a laboratory test. This can help your doctor diagnose problems that can be seen in your urine.
Many diseases and disorders affect how your body eliminates waste and toxins. The organs involved are your lungs, kidneys, urinary tract, skin and bladder. Any of these problems can affect the appearance, concentration, and content of your urine.
Uranalysis is not like a drug screening or pregnancy test, although all three tests include urine samples.
Why urinalysis is done
Uranalysis is often used:
- Before surgery
- As an important screening during a pregnancy checkup
- As part of a routine medical or physical examination
Your doctor may also order this test if they suspect you have certain conditions, such as:
- Kidney disease
- Liver disease
- Urinary tract infection
If you have already been diagnosed with any of these conditions, your doctor may use urinalysis to check the progress of the treatment or the condition.
If you experience any symptoms, your doctor may also want to do a urinalysis, including:
- Stomach pain
- back ache
- Blood in your urine
- Painful urination
Preparation of urinalysis
Before your test, make sure you drink plenty of water so that you can give a proper urine sample. However, drinking too much water can have the wrong consequences.
One or two extra glasses of fluid, which may include juice or milk, if your diet allows, you need on the day of the test. You do not need to fast or change your diet for the test.
Also, tell your doctor about your medications or supplements you are taking. Some of the things that can affect your urinary outcome include:
- Vitamin C supplements
- Anthraquinone laxative
- Mito carbamol
Some other medications may also affect your results. Tell your doctor about the substances you use before urinating.
About the process of urinalysis
You will have your urine sample taken at a doctor’s office, hospital, or special examination facility. You will be given a plastic cup to go to the bathroom. There, you can urinate privately in a cup.
You may be asked to take a clean urine sample. This technique helps prevent bacteria from entering the sample from the penis or vagina. Start by cleaning around your urethra. Clean with the cleaning provided by a doctor. Make small amounts in the toilet, then collect the sample in the cup. Avoid getting inside the cup so that you do not move the bacteria into the sample with your hands.
When you are done, put the lid on the cup and wash your hands. You will either bring the cup out of the bathroom or leave it in a designated box inside the bathroom.
In some cases, your doctor may ask you to have a urinalysis using a catheter that enters your bladder through the urethra. This can cause minor discomfort. If you are not bothered by this method, ask your doctor if there is an alternative method.
After providing your samples, you have completed your part of the test. The sample will then be sent to the lab or they will remain in the hospital if they have the necessary equipment.
Methods of urinalysis
Your doctor will then use one or more of the following methods to check your urine.
On a microscope examination, your doctor looks at your urine droplets under a microscope. They find:
- Abnormalities in your red or white blood cells, which could be a sign of an infection, kidney disease, bladder cancer, or blood disorder
- Crystals that can identify kidney stones
- Infectious bacteria or yeast
- Epithelial cells, which can identify tumors
For a dipstick test, your doctor inserts a chemically treated plastic stick into your sample. The rod changes color depending on the presence of certain substances. This can help you find your doctor.
- Bilirubin, a product of the death of red blood cells
- Protective or special traction
- Changes in pH level or acidity
The high number of particles in your urine may indicate that you are dehydrated. High pH levels can indicate urinary tract or kidney problems. And any presence of sugar can be a sign of diabetes.
Your doctor may also test for abnormalities, such as:
- Cloudy appearance, which may indicate an infection
- Unusually stinky
- A reddish or brownish tinge, which may indicate blood in your urine
When your urinalysis results are available, your doctor will review them with you.
If your results look unusual, there are two options.
If you have previously been diagnosed with kidney problems, urinary tract problems or other related conditions, your doctor may order further tests or other urine tests to identify the cause of your abnormal urinary tract. Can give
If you have no other symptoms of the underlying condition and a physical examination shows that your overall health is normal, your doctor will not need follow-up.
Protein in your urine
Your urine usually contains less protein than you need. Sometimes, the level of protein in your urine can rise because of:
- Excessive heat or cold
- Stress, both physical and emotional
- Excessive exercise
These factors are usually not a sign of a major problem. But abnormal amounts of protein in your urine can be a sign of underlying problems that can lead to kidney disease, such as:
- Heart conditions
- High blood pressure
- Scale cell anemia
- Joint ossification
Your doctor may order a follow-up test to identify any conditions that may be caused by abnormally high protein levels in your urine.
Following urinary incontinence
If your urinalysis results come back abnormal, your doctor may need additional tests to determine the cause. These may include:
- Blood tests
- Imaging tests such as CT scans or MRI
- Comprehensive metabolic panel
- Urine culture
- Complete blood count
- Liver or kidney panel
