Blot excess fluid from the arm, taking care to not cross contaminate the check sites.
The check(s) ought to be in the course of a negative management test with the solvent used for the extracts. (A positive management check with aminoalkane resolution may be used).
Interpretation of diagnostic test reactions
Scrutinise the course of reactions at intervals. The definitive check result's browse once about ten minutes. A positive management check reaction presents as a pale harm (oedema) with a encompassing halo of red (erythema).
Assess the strength of every reaction by the degree of erythroderma and therefore the space of the harm fashioned. Record the strength of every reaction relative to the management as follows:-
-
No wheal. erythroderma absent or but one millimetre diameter.
+
Wheal absent or terribly slight. erythroderma gift, less than three millimetre diameter.
++
Wheal less than three millimetre diameter, with associated erythroderma.
+++
Wheal between three millimetre and five millimetre diameter, with erythroderma.
++++
Any larger reaction, probably with pseudopodia
Although some patients can provides a reaction to the management resolution, they'll sometimes offer considerably larger reactions to the allergens to that they're clinically sensitive.

• The patient ought to be tutored to not rub or scratch the check web site.
Anaphylactic shock
Systemic hypersensitivity reaction following prick testing is sort of unknown. The operator ought to have adequate expertise to differentiate hypersensitivity reaction reaction from different reactions a lot of probably to be seen throughout skin testing, e.g. vasovagal, external respiration etc, and to manage those reactions fitly.
Warning symptoms include:
Tingling, cutaneous sensation and burning sensations on the tongue, within the mouth, throat or notably on the palms and soles. this could be in real time followed by shock with symptom, cardiovascular disease, arrhythmia, spasm and cognitive state.
