Allergy tests, Does it were really accurate?
Allergy tests are performed in the lab is not necessarily providing accurate results; it is consistent with the results of a study published in The Journal of Pediatrics, the United States. Although allergy tests are often able to justify the suspicions held against the patient’s allergies one particular type of food and materials, but in reality it does not render the absolute results.
Allergy tests in the lab is generally done in two ways, namely through a blood test and use the awl tool provided little material suspected of being able to give effect to the skin allergy. By the time someone had an allergy test, 8% of children who undergo these tests will have positive results have allergies but in fact only 1% that actually show physical symptoms of the allergy in question.
Thus it is proved that the best way to see a person’s allergies is through direct experiment eating foods suspected, the doctor’s supervision and with the dose of medication that a few others. So it will be able to show tangible results as The Gold Standard in diagnosing food allergy.
Even Dr. Robert Wood allergy specialist at Johns Hopkins Children’s Center also confirmed that there are many children in a positive allergy tests results showed no allergic symptoms nor vice versa, children who are not proven in tests, were able to show real symptoms of allergy. So he argues that even if not accurate, at least an allergy test is able to provide warning of the possibility of specific allergy in children and adults. Meanwhile, according to the National Institutes of Health, USA, 3% of adults and 6% of children have at least one type of food allergies.
