What You Need to Know About Allergy Testing

Runny nose, sneezing, and itchy eyes are signs that you could be having an allergic reaction but you might not know the cause. Allergy testing at Urgent Care TX, in Lancaster, TX, and Cleburne, TX, can help you identify your triggers.

Allergy Testing

Allergy testing helps you identify the allergens that trigger your reactions. During allergic reactions, your body's defenses go into overdrive to produce exaggerated responses to factors in your environment.

Common signs of allergic reactions include:

  • Runny nose
  • Sneezing
  • Itchy, watery eyes
  • Coughing
  • Itchy skin
  • Itchy nose and throat
  • Exaggerated responses to an insect bite

Allergy testing might involve skin tests, blood tests, elimination diets, and challenge tests.

Skin Test

Skin allergy testing at the Urgent Care TX, facilities in Lancaster and Cleburne, TX, typically takes a few minutes. The test could be either a scratch, intradermal, or patch test. Your doctor would typically perform these tests on your forearm or upper back.

For scratch tests, the allergists place the potential allergen on your skin and scratch your skin surface with a special instrument. After the waiting period, they would inspect your skin for signs of a reaction such as redness and inflammation like you would get from a mosquito bite.

Inconclusive scratch tests might lead your allergists to suggest an intradermal test where they inject the allergen into your skin.

Patch tests take longer to complete as you would need to wear the patch for about 48 - 96 hours for observation.

Blood Tests

Medications such as antihistamines could interfere with the results of your skin allergy test. Your doctor might ask you to stay off such medications for a few days before your test. However, if you can't give up your medication, your allergist might carry out a blood test for antibodies instead.

Blood tests need a few days for processing, so you won't get your results immediately.

Elimination Diets

Elimination diets involve removing selected items from your diet and gauging your reaction as they reintroduce them. If you have a risk of severe allergic reactions, your allergist might not recommend this test.

Challenge Test

Challenge tests expose you directly to potential allergens. For instance, you might have to inhale pollen or eat certain food to observe your reaction.
