متن کاملComparison of different diagnostic products for skin prick testing.
BACKGROUND Different in vivo methods are used to quantify the amount of allergens in products for skin prick testing. It is unclear how this impacts on the correct diagnosis of allergies. AIM OF THE STUDY We compared the allergenic potency of three commercial extracts for skin prick testing and evaluated batch-to-batch differences within each product. METHODS Patients with a mono-sensitizat...
متن کاملAre skin prick tests really safe? A case of anaphylaxis caused by skin prick testing with inhalant allergens.
Skin prick test (SPT) which is widely used to demonstrate an immediate IgE-mediated allergic reaction is a major diagnostic work-up in the field of allergic diseases. SPT is cheap, easily performed and provides a response within a few minutes. This test is generally considered a very safe procedure. Although the frequency of systemic reactions caused by extracts of inhalant allergens is extreme...
متن کاملFaster and Simpler Minimal Conflicting Set Identification
Let C be a finite set of n elements and R = {r1, r2, . . . , rm} a family of m subsets of C. A subset X of R verifies the Consecutive Ones Property (C1P) if there exists a permutation P of C such that each ri in X is an interval of P . A Minimal Conflicting Set (MCS) S ⊆ R is a subset of R that does not verify the C1P, but such that any of its proper subsets does. In this paper, we present a ne...
متن کاملIntradermal Skin Testing in Allergic Rhinitis and Asthma with Negative Skin Prick Tests.
Taking medical history, physical examination, and performing some in vivo and in vitro tests are necessary for the diagnosis of allergy. Skin prick test (SPT) is considered as the standard method and first-line approach for the detection of allergic sensitization. Although mainly SPT is used for the detection of allergic sensitization, intradermal skin test (IDST) may be necessary, especially i...
