When you go to see a doctor, you are often asked to give a urine sample, right? While this may seem normal to some, others may wonder, "Why is this urine test being done? What does this report say?" In fact, your urine is like a mirror that tells a lot about the health of your body. So today, let's talk about this urine test , or ` Urinalysis `.
What is this urine test (Urinalysis)?
Simply put, `Urinalysis` is a process of taking your urine (pee) and running a series of tests on it. It is also known by other names like `Urine Test`, `Urine Analysis`, `UA`. Doctors use this test to check for common diseases or symptoms of a health condition in our body.
Why does the doctor ask you to do a urine test?
There may be several reasons for this.
- As part of a routine health checkup: This test can be done to get an idea of your overall health, just like during your annual `full check-up`.
- Detect diseases early: This is a good way to detect some diseases at an early stage. For example:
- Kidney disease
- Liver disease
- Diabetes
- For other medical procedures: This test can be done if you are preparing for surgery or are about to be admitted to the hospital. It is also a mandatory part of the tests performed during pregnancy.
- Find the cause of your symptoms: If you have symptoms of a urinary tract infection or kidney problems (e.g., burning sensation in the bladder , frequent urination , back pain), this test can help determine the exact cause.
- Monitor an existing condition: If you already have a condition like kidney disease, this test is also done regularly to see how it changes over time.
How do you do this test? There are three ways to do it!
The urine sample you provide is tested in three main ways. You may be tested using all three methods.
1. Visual Exam
This involves visually examining the color and clarity of the urine. Imagine,
- If there is blood in your urine, it may be a dark brown color, similar to red.
- If the urine is foamy , it could be a sign of kidney disease.
- If your urine is dark (cloudy), it could be a sign of an infection.
2. Microscopic Exam
This involves looking at things that are too small to be seen with the naked eye through a microscope. Here are some things that are not normally seen in healthy urine, but can be found under a microscope:
- Red blood cells
- White blood cells
- Bacteria (`Bacteria`)
- Crystals - These are small lumps of minerals that form when they accumulate. Their presence can be a sign of kidney stones.
3. Dipstick Test
This is the most important part of the report that most people will see. This involves dipping a thin plastic strip coated with chemicals into your urine sample. If there are higher than normal levels of certain substances in your urine, the chemicals on the strip will react and change color. The tests for these substances are listed in the table below.
| What is being tested (Component) | What does it indicate? (What it indicates) |
|---|---|
| Acidity (or pH) | If this value is abnormal, you may have kidney stones, a urinary tract infection (UTI), or another condition. |
| Protein | This could mean that your kidneys are not working properly. The kidneys are responsible for filtering waste products from the blood. |
| Glucose (sugar) | Elevated sugar levels in the urine are a major symptom of diabetes. |
| White Blood Cells | These symptoms indicate an infection or inflammation somewhere in the kidneys or urinary tract. |
| Nitrites | If these are present, it means there is an infection caused by a specific type of bacteria. |
| Bilirubin | This is a waste product that is normally excreted by the liver. If it is present in your urine, your liver may not be functioning properly. |
| Blood | Sometimes this is a sign of infection. It can also be a sign of other medical conditions. |
Do we need to prepare before the test?
If you are only doing a urine test, you can eat and drink normally. However, things like beetroot or food dyes can change the color of your urine. So it is best to avoid eating such things the day before the test.
The most important thing is to tell your doctor about all the medications you take (including vitamins and supplements) . If you are having the test while you are on your period, let your doctor know ahead of time.
How to give a urine sample correctly? (Clean Catch method)
For best results, you should follow the "Clean Catch Method." The lab will give you instructions on this before they give you the sample. But it's good to know. Here are the steps:
- Wash and clean the urethra and surrounding area thoroughly with soap.
- First, empty some urine into the toilet.
- Now stop urinating in the middle .
- Next, add about 1-2 ounces (30-60 milliliters) of urine to the cup you are given.
- Empty the remaining urine back into the toilet.
- Then, submit the sample according to the instructions from the lab or doctor.
For those who cannot give a sample in this way, such as small babies, a doctor can take a sample by inserting a soft, thin tube called a `catheter` through the urethra into the bladder.
What is the meaning of what is said in this report?
This is the most important thing. A urine test report is just one piece of information about what's going on inside your body. It can show warning signs , but it can't determine for sure that you have a disease from this report alone.
Remember, a urine test report is just one piece of information about your health. If it gives you any clues, you may need to do more tests to investigate further.
If your results are slightly different, but you have no other symptoms, your doctor may not need to do any further testing. However, if you already have a urinary tract infection or kidney problems, this report can help your doctor adjust your treatment plan.
So, the best thing to do is not to panic after seeing the report, but to take it and talk to your doctor about it. He or she will explain what it means and, if necessary, advise you on what to do next.
