How are your kidneys? Let's learn about the 24-hour urine test.

Hello! How are you? Today we are going to talk about a test that is a little new to many people, but sometimes very important. That is the 24-hour urine test, or in English `(24-hour urine test)`. Perhaps your doctor has told you about this, or you are curious to know about it. Let's see what it is, why it is done, and how it is done.

What is a 24-hour urine test?

Simply put, this is a test that helps your doctor see how well your kidneys are working . It involves collecting urine (also called urine ) over a 24-hour period. This urine sample is used by doctors to check the levels of things like protein , albumin , and creatinine in your urine. The levels of these things can help determine whether you have any diseases that affect your kidneys, or how well they are being controlled. This is a very important test, because your kidneys are like the silent workers in your body. We don't notice much unless they are working properly.

When do we need this 24-hour urine test?

Now you may be wondering, 'Do I need this?' A doctor will usually order this test if they have already done other tests to check your kidney function - such as a urinalysis or blood test - and need more information. The results can help your doctor diagnose conditions such as these, or assess the condition of someone who has them:

• Alport syndrome
• Bladder cancer
• Kidney stones
• Heart failure-like conditions
• High blood pressure
• A cancer condition called ``Multiple myeloma``
• Nephrotic syndrome. This can be caused by conditions such as amyloidosis, diabetes-related nephropathy, and lupus nephritis.
• Preeclampsia, a condition of high blood pressure during pregnancy
• Rhabdomyolysis, a condition of muscle damage
• Urinary tract infections (UTIs)

Don't be scared when you see this list, okay? This doesn't mean that you can have all of these diseases. A doctor only recommends this test to confirm if there is any doubt.

How do you collect urine for 24 hours?

What happens here is very simple. You collect urine every time you urinate for a day, which is exactly 24 hours.It happens. Your doctor or the lab will give you a special bottle (maybe several bottles) for this. They will also give you instructions on how to do it correctly. After collecting urine for 24 hours, you will need to take the bottle to the appropriate lab to be tested. Think of it like collecting a sample of your urine throughout the day, and that can tell you a lot about the health of your kidneys.

How should we prepare before this test?

To do this test well, you need to have a little preparation. Here are a few things to consider:

• Choose a day when you can stay home most of the day. That way, you can collect each urine sample without any difficulty. If you have to leave the house, you'll want to take that urine collection bottle with you, because you don't want to miss a single urine sample.
• There should be a way to keep the urine collection bottle cold throughout the day . A fridge would be good. Or you could keep it in an ice pack.
• Your doctor may tell you to avoid exercise for 24 hours before the test and on the day of the test, as excessive exercise can affect some of the results.
• Follow your doctor's instructions about what you can and cannot eat on the day of the test and the day before. This is very important, as some foods and drinks can affect the results.
• Tell your doctor about any medications you are taking, as well as any supplements, vitamins, and herbs you are using, as some medications can affect the results of this test.

What should we not do during the test?

It's best to talk to your doctor about what you can and can't eat before and on the day of the test. You can usually avoid things like:

• Caffeine-containing beverages like coffee and tea.
• Things that contain nicotine, like smoking.
• Alcohol.
• Some fruits (e.g. bananas, avocados), vegetables (e.g. eggplant, tomatoes) and fruit drinks (e.g. orange juice).
• Vitamins, supplements, or certain medications.

But remember, don't stop taking any medication until your doctor tells you to. This is very important!

How do I accurately collect a 24-hour urine sample?

Okay, now let's see how to collect this urine properly. This is something that needs to be done with some care. Here are some general instructions:

1. First thing is, don't collect your first urine when you wake up in the morning. Just pass it into the toilet as usual. But write down the exact time. This is the time to start your test. Let's say you passed your first urine at 8 am (and didn't collect it). So 8 am is the time to start.

2. ThenEvery time you urinate, collect it in the bottle provided. Be very careful here to make sure that all of your urine goes into the bottle, and that no feces (we also call it goo) or toilet paper gets into it. This is not too difficult because the bottle has a wide mouth.

3. When you're not using the urine bottle, keep it in the fridge. Or you can keep it in a cool box with ice. The main thing is that it's cold.

4. Drink plenty of water throughout the day. You can eat normally, except for things your doctor specifically tells you not to eat.

5. You should mark the time you started the test, exactly 24 hours later, and try to collect your last urine as close to that time as possible. For example, if you voided your first (uncollected) urine at 8 a.m. on Monday, try to collect your last urine around 8 a.m. on Tuesday.

6. Don't forget to clearly write your name, the time the test started, the time it ended, and any other necessary details on the bottle. The lab may provide a sticker to write these details on.

7. Take this bottle to the lab as soon as possible. Your doctor will tell you where to take it.

The most important thing is to follow any additional instructions your doctor gives you (such as when to start collecting, how to use the bottle, etc.) very carefully. Only by following the instructions exactly will you get the most accurate results.

How much water should we drink on the day we collect this urine?

It is generally recommended that you drink about 8 glasses of water on the day of your urine collection. A glass of water is about 180-240 milliliters (6-8 ounces). However, if you have a condition such as kidney disease that restricts your water intake, ask your doctor for advice.

Are there any risks in doing this test?

There is really no harm or risk to you from having this test. It is not painful in any way. However, there is a small chance that the results may be incorrect if the sample is not collected properly or for some other reason. Here are some of the reasons:

• Collecting urine for more or less than 24 hours, or skipping urination during that time. Missing even one urination may change the result.
• Certain foods, medications, or supplements.
• Excessive exercise.
• Extreme stress.
• Dehydration is a lack of water in the body.

That is why it is important to follow the doctor's instructions exactly.

What are the results of collecting this 24-hour urine sample?

Your test report shows the total level of protein in your urine, and the protein/creatinine ratio.You can find out. At the same time, the lab also gives you a ``reference range.'' This tells you what the results should be for a normal, healthy person. So the doctor comes to a conclusion by comparing your results with this standard range.

What are the typical results of a 24-hour urine test?

For an adult, a protein level of less than 150 milligrams per day (`< 150 milligrams per day`) and a protein to creatinine ratio of less than 0.2 (`< 0.2`) are considered normal. If it's higher than these values ​​(we also call this condition `proteinuria`), it could mean that your kidneys are not working properly. But don't worry if your results are a little high once in a while. Your doctor will look into the cause.

How long will it take for me to know the results?

It can take a few days for the results of this 24-hour urine test to come back. Some labs may even have the results the same day. You can ask the lab when you submit the sample and when you can expect the results.

If the results are abnormal, what happens next?

If your results are abnormal, meaning they are not what the doctor expected, he or she will talk to you and decide what to do next. This may include making a diagnosis, deciding on treatment, or doing additional tests . For example, a kidney scan or, if necessary, a biopsy. All of this is done to give you the best treatment.

When should I call my doctor ?

If you have any questions about how to collect your urine sample, if there is anything that is unclear, or if you want to know what the test results mean , be sure to talk to your doctor or healthcare provider. Don't keep anything to yourself. It's best to ask.

Finally, things to remember

There are many reasons why you might want to do this, whether it's to monitor a condition you already have or to get more information after other tests.
