If you previously had a reaction to bee stings, this could suggest you might be allergic to bee venom. Your doctor will order for one or both of the following tests. Skin test: A small amount of insect venom (in this case, bee venom) is injected into your arm or upper back. If you are allergic, you will develop a raised bump at the site of the test. Allergy blood test: By measuring the number of allergy-causing antibodies in your bloodstream, a blood test can assess your immune system's response to bee venom. Allergy skin tests and allergy blood tests are often used together to diagnose insect allergies.
