Allergy Testing Q&A

Commonwealth Medical Center

What exactly is an allergy?

An allergy is a chronic reaction caused the body’s incorrect overreaction to certain substances. When your body incorrectly identifies a foreign substance, such as pollen or tree nuts, as harmful, it attacks it with antibodies called immunoglobulin E (IgE) and histamines. Histamines cause the symptoms of an allergic reaction, such as swelling and hives.

How do allergists test for allergies?

The Commonwealth Medical team tests for allergies using blood serum testing, formerly known as RAST testing. Serum testing is superior to traditional skin testing because it’s:

  • Less painful
  • Less upsetting to sensitive skin
  • Useful for the testing of up to 56 allergies
  • Less risky


On top of that, with serum testing, you don’t have to abstain from using histamines or medicines that could interfere with skin testing beforehand.

To perform these tests, a Commonwealth Medical Center team member simply draws your blood and tests it at their lab facility. The blood draw is quick and may feel like a little pinprick. To get results, the team member mixes your blood with small amounts of allergen-specific serum and waits to see if your blood produces IgE antibodies. If it does, this means that you’re likely allergic to the substance in the serum.

If you suspect you or your child is suffering from an allergy, or if you’d just like to get tested, make an appointment with the caring team at Commonwealth Medical Center. Or, if you’re experiencing an active allergic reaction that isn’t life-threatening right now, walk into Commonwealth Medical Center’s urgent care center.
