You've probably heard that when you go to see a doctor for a cold or cough, they'll probably ask you to take a small sample from your nose. That's what we call a nasopharyngeal swab test. While the name may sound a bit complicated, it's actually a simple test that can help diagnose many illnesses, especially respiratory infections. So, let's talk about it in more detail today, shall we?
What exactly is this so-called nasopharyngeal swab?
Simply put, this is a type of nasal swab. A doctor uses it to check for bacteria or viruses that can cause infections in your respiratory system. This involves taking a sample of cells from the inside of your nose, just above the throat, which is what we medically call the nasopharynx .
The instrument we use for this is called a swab. You may have seen it, it looks like an ear swab, but this one is longer. This swab has a long, thin rod. It's often made of flexible plastic or wire. It has a little cotton-like part on one end. That part is what you use to suck up some of the liquid secretions in your nasopharynx.
Who is doing this test? Can't we do it ourselves at home?
This is a very important point. This nasopharyngeal swab test is performed by a trained healthcare worker, either a doctor, a nurse, or someone who has received special training for it.
There are some nasal swab tests that only take a sample from the front of your nose. They may be instructed to do it yourself. However, this is not the case with a nasopharyngeal swab. This is not something you can do on your own.
Because this swab needs to be taken a certain distance into the nose. If it is not done properly, some problems can occur. Therefore, this should definitely be done by an experienced person.
When is this Nasopharyngeal Swab test needed?
If your doctor suspects that you have a respiratory infection, he or she may ask you to do this test. Here are some examples:
- You may have heard a lot about this test during the COVID-19 pandemic.
- Influenza , which is what we commonly call the "flu," is a common condition.
- Pertussis (Whooping Cough) This is a cough that can be especially dangerous for young children.
- Meningitis , also known as "brain fever," is a serious infection of the brain.
- RSV (Respiratory Syncytial Virus) is a virus that can cause respiratory problems in young children and the elderly.
- If you suspect an infection with MRSA (Methicillin-resistant Staphylococcus aureus) , a bacterial strain that is resistant to some antibiotics.
Why would a doctor think you need this test? Are there any symptoms that would make you think so?
Yes, there are several symptoms that can indicate that you have a respiratory infection. A doctor will consider this test only if they see symptoms like these.
Imagine that you have had a high fever for several days, a cough, and a sore throat. Or you have a stuffy nose, runny nose, body aches, and fatigue. At a time like this, your doctor may suspect that you have an infection.
These are the symptoms that are commonly seen:
- Sore throat
- Cough
- Headache
- Fever
- Runny nose (without nasal congestion)
- Nasal congestion
- Body pain (muscle soreness)
- Feeling very tired
If you have one or more of these symptoms, your doctor may recommend a nasopharyngeal swab test to determine exactly what the cause is.
How is this nasopharyngeal swab test performed? Please explain a little.
Okay, let's see how this is done. As I told you before, this is done by a trained health worker.
1. First, you will be asked to tilt your head back slightly and hold your nose slightly up. This will straighten the nasal passage, making it easier to insert the swab.
2. Then, the doctor or nurse will slowly insert the long swab into one of your nostrils. They will push it in slowly until it reaches the nasopharynx, which is the very top of your throat.
3. While the swab is still in the nose, the doctor will slowly rotate it two or three times. This is done to ensure that the cells and secretions in that area are well-attached to the cotton-like tip of the swab. Sometimes, they leave it there for a few seconds before slowly removing it.
4. Usually, a sample from one nostril is sufficient. However, sometimes, if you feel that the sample is not coming out right, you can try to take a sample from the other nostril as well.
This may sound a little scary, but it will be over very quickly.
Do I need to prepare anything in particular before this?
In most cases, you do not need to do anything special to prepare for this nasopharyngeal swab test.
However, if you are being tested for COVID-19, you may sometimes be asked to blow your nose with a tissue before the test. This is to remove any debris from the front of your nose and to make the sample clear.
What should I expect during the test? Will it hurt?
To be honest, this is not completely painless. The swab is inserted through the nose and goes all the way into the ear, so it can feel a little uncomfortable. Some people may just feel a tickling sensation, while others may feel a slight pressure inside.
Also, when the swab hits the nasopharynx, you may experience a brief cough or gag reflex. This is normal, so don't worry. The discomfort only lasts a few seconds.
Try to stay as relaxed as possible. Taking deep breaths and exhaling slowly may help.
What happens after the test? How do I get the report?
The sample taken from you is carefully placed in a special container, sealed, and sent to a lab. There, it is tested for any germs.
Your doctor is the one who tells you the results from the lab.
- If the result is negative: It means that you do not have the disease for which you were tested.
- If the result is positive: It means you have the disease in question.
Are there any risks with this test?
The Nasopharyngeal Swab test is generally a very safe test. However, there are a few things that can happen very rarely:
- Some people may experience a small amount of nosebleed after the test. This usually stops on its own.
- Very rarely, the swab can break and get stuck inside. But this happens very rarely.
- If the test is not performed properly, the results may be incorrect due to insufficient sample collection.
That's why we've said before that this test should definitely be performed by someone who is trained and has a good understanding of the anatomy of your nasal cavity. That way, you can minimize these risks and get an accurate result.
How soon can I get the report?
This depends on several factors.
If the lab is close to where you gave the sample, you may be able to get results quickly. For example, some rapid antigen tests can give results in minutes. However, something like a PCR test can take hours or even a day or two to analyze using laboratory equipment.
If you need to send your sample to a lab in another city, it will take a little longer. It also depends on how many tests are available at the lab at that time.
When you get tested, the people there usually tell you when you can expect the results. If you don't get them by the time you were told, talk to your doctor and ask about it.
Finally, things to remember
No one likes to have a nasopharyngeal swab test. However, the slight discomfort is temporary.
The information from this test is very valuable to your doctor. It helps them figure out exactly what is causing your illness.
Once you know what's wrong, you can start the treatment you need to get better quickly. Your doctor can give you the right advice and help you get back to your normal health.
So, if a doctor tells you to do this test, don't be afraid of it, do it. It's for your own good. Got it?
