A common allergy test, Skin Prick Test (SPT), is a simple, safe and quick test. It requires about 15-20 minutes and gives a quick diagnosis and management plan. This test is done by introducing a small amount of allergen into the skin which leads to a localized allergic response. This may be in the form of a flare (redness) or wheal (bump) at the site of testing. SPT is safe to use on all age groups, including babies. The skin prick test is normally done on the inner forearm, but, can also be done on other parts of the body like thigh or back etc. The allergens used as test are selected on the basis of discussions between the patient and the clinician. Up to 25 allergens can be tested in a single go.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
