Questions 1-5. Read the passage below and decide whether the statements are TRUE or FALSE
If you've had a reaction to bee stings that suggests you might be allergic to bee venom, your doctor may suggest one or both of the following tests:
Skin test. During skin testing, a small amount of allergen extract (in this case, bee venom) is injected into the skin of your arm or upper back. This test is safe and won't cause any serious reactions. If you're allergic to bee stings, you'll develop a raised bump on your skin at the test site.
Allergy blood test. A blood test can measure your immune system's response to bee venom by measuring the amount of allergy-causing antibodies in your bloodstream. A blood sample is sent to a medical laboratory, where it can be tested for evidence of sensitivity to possible allergens.
