Allergy Tests & Sinus Infections

Sinusitis, caused by bacterial, fungal or viral infections, is an inflammation of the sinuses. People who suffer from allergies are more prone to sinus infections. It is estimated that 37 million people suffer from sinusitis each year, according to the Ear Nose and Throat Testing and Treatment Center. Allergy testing can help determine the cause of recurrent sinus infections.

Sinuses

• The sinuses are cavities, filled with air and lined with mucous membranes, located in your skull. They are behind the forehead, eyes, cheeks and nasal bones.

Infection

• If the sinuses become inflamed, they can become blocked with mucous and cause an infection called sinusitis. A sinusitis infection can be viral, bacterial or even fungal.

Allergies

• Allergies can cause a person to sneeze and become congested. This is because when the person is exposed to one of his allergens, plant pollen or animal hair, for example, his body releases the chemical histamine. Histamine causes swollen membranes. Prolonged congestion from allergies can lead to sinusitis.

Allergy Testing

• Allergy testing is conducted intra-dermally, which means under the skin. A small amount of a potential allergen is injected underneath the skin, then swelling is measured about 15 minutes later. If allergens are identified, they can be avoided or you can take medication to help with the allergic reaction.

Sinusitis Diagnosis

• To diagnose sinusitis, the physician may shine a light on the sinuses or tap the sinuses. Material from the nose may also be tested at the lab. X-rays are also sometimes performed. Sinusitis is generally treated with antibiotics, plenty of fluids and a warm cloth applied to the sinuses several times daily.
