Allergy screening test is a part of the diagnosis and treatment process available for those who suffer from allergies. It can also help identify the exact substance which is causing the patient’s allergies.
Allergy screening may be carried out either by a Skin Prick Test or by Blood Tests for specific IgE, both of which can help identify allergies to various substances, including house dust mite, animal dander, cockroaches, pollen, mold, food or medication.
There has been a large amount of researches looking into comparisons between Skin Prick Test and Blood Sample Test and it has been found that the results of both are extremely similar, with little to choose between them. Nevertheless, each method has its own benefits and disadvantages. So patients should give careful consideration to both before making a decision.
Allergic screening test can inform doctors about exactly which substances the patient is allergic to, helping them provide a more accurate diagnosis than when only performing a basic health checkup or analysis of the patient’s medical history. When we become aware of what we are allergic to, we can avoid those substances altogether, thereby helping alleviate the symptoms of allergies faster than through medicated treatment alone. However, in some cases, when an allergy has been identified, doctors may consider the treatment in the form of Allergen Immunotherapy.
When a patient has suffered from long-term or recurrent symptoms and suspected the cause from allergies. The symptoms include:
If patients are allergic to any of the substances, they will show red and itchy bump around the area of skin where that particular allergen was placed.
In preparation for the screening, patients must abstain from any antihistamine and sleep medications for a period of 7 days prior to the day of screening in order to ensure the highest levels of accuracy.
Although skin testing is one of the simplest and safest forms of allergy screening, there is still a risk of a severe allergic reaction occurring. However, the chance of such an occurrence is one in a million. Nonetheless, it is advised that patients undergo this screening in an accredited hospital which has specialist doctors available to carry out the assessment, explain the results, and provide treatment.
