Sputum Test: Purpose, Procedure, and What to Expect

A sputum test is a simple medical test that checks for germs or problems in your lungs. Doctors often use a sputum test to find out if you have an infection or another lung issue. Because it helps find the cause of coughs or breathing trouble, a sputum test is very important for your health.

What Is a Sputum Test?

Simply put, a sputum test looks at mucus from your lungs. This mucus, called sputum, comes up when you cough deeply. Unlike saliva, sputum comes from your lungs, not your mouth. Doctors use this test to check for infections, such as tuberculosis or pneumonia. Sometimes, it also helps find out if you have allergies or other lung diseases.

Why Is a Sputum Test Done?

Doctors order a sputum test for many reasons. For example, you may need it if you have a cough that will not go away. In addition, if you have chest pain, fever, or trouble breathing, your doctor may suggest this test. Here are some common reasons for a sputum test:

To find out if you have a lung infection, like pneumonia or bronchitis

To check for tuberculosis (TB)

To see if your asthma or allergies are causing problems

To help choose the right medicine for your infection

According to the CDC, sputum tests are key for diagnosing lung infections and guiding treatment.

How to Prepare for a Sputum Test

Getting ready for a sputum test is easy. However, following a few steps can help you get a good sample. Here are some tips:

Drink a glass of water before the test to loosen mucus

Brush your teeth and rinse your mouth, but do not use mouthwash

Try to collect sputum first thing in the morning

Follow your doctor’s instructions closely

Sometimes, your doctor may ask you to avoid eating or drinking for a few hours before the test. Always check with your healthcare provider for special instructions.

The Sputum Test Procedure: Step by Step

Many people wonder about the sputum test procedure. The process is simple and safe. Here is what usually happens:

First, you will be given a clean container.

Next, take a deep breath and cough hard from your lungs.

Spit the mucus (not saliva) into the container.

Repeat until you have enough sputum, usually about a teaspoon.

Finally, close the container tightly and give it to the nurse or lab staff.

Sometimes, if you cannot cough up sputum, your doctor may use a saline mist to help loosen it. This makes it easier to collect a sample.

What Do Sputum Test Results Mean?

After the lab checks your sputum, your doctor will explain the results. The test can show if you have an infection, and what type of germ is causing it. For example, the results may show bacteria, viruses, or fungi. This helps your doctor choose the best treatment. If the test finds tuberculosis, you may need more tests or special medicine. In some cases, the sputum test results may be normal, which means no infection was found.

Risks and Safety of Sputum Tests

For most people, a sputum test is very safe. There are almost no risks. However, coughing hard may cause a sore throat or mild discomfort. Rarely, people with certain lung problems may feel short of breath. If you feel dizzy or have trouble breathing during the test, tell your doctor right away. Overall, the benefits of a sputum test far outweigh the risks.

Tips for Accurate Sputum Collection

To get the best results, it is important to collect a good sputum sample. Here are some helpful tips:

Always collect sputum, not saliva

Try to cough deeply from your chest

Collect the sample in the morning, if possible

Follow all instructions from your healthcare provider

Do not eat or drink right before the test, unless your doctor says it is okay

With these steps, you can help make sure your sputum test for infection is accurate.
