How is a sore throat diagnosed?

There are many different ways to diagnose a sore throat. Your doctor may examine you, review your medical history, or order tests and / or imaging tests.

Throat culture

A throat culture is a test in which the back of the throat is rubbed with a long cotton swab. The swab is usually sent to a laboratory to test for the presence of bacteria. If it is a rapid strep test, you will get immediate results.

Rapid strep tests can sometimes give false negative results. For this reason, the throat culture is usually sent to the laboratory for further testing. After a day or two, you may be called in to confirm the diagnosis of pharyngitis .

A sore throat caused by sinusitis or nasal infections can be diagnosed with a throat culture. Your doctor may also take samples of your sputum , the material you cough up.

Allergy tests

Blood tests or allergy skin tests can tell your doctor if your sore throat is caused by an allergy.

During a skin test, your doctor exposes you to an allergen through a small scratch on the skin, something you may be allergic to. If you are allergic, you will have a reaction. Blood tests also look for antibodies (immune system proteins) against specific allergens.

Skin test results are available immediately. Blood test results can take several days.

Drug trials

Test medications for acid reflux can help your doctor find the cause of your sore throat. If you respond to treatment, your doctor may diagnose you with acid reflux.

Also, trying antihistamines can help your doctor diagnose allergies. This can be done before an allergy test.

Display

Medical images, including computed tomography (CT) , ultrasound, or magnetic resonance imaging (MRI) , can be used to diagnose a sore throat. This can be done if the suspected cause is a tumor, swelling, or sinusitis.

Acid reflux and similar problems are often diagnosed with an upper endoscopy.

Another test that can be used is to swallow barium . During this test, you will be asked to drink a thick solution that contains barium. The barium covers the esophagus and stomach so they can be seen on x-rays.

Physical exam

Your doctor will also do a physical exam to examine your throat and feel your neck. You will also be asked about your symptoms and medical history.

Your doctor will examine you for lumps or bumps in your throat. The lump that accompanies a sore throat may be a lymph node . It could also be something more disturbing. If your doctor cannot identify it as a lymph node, you may need a biopsy.
