A percutaneous test used to identify a patient’s allergic response to various allergens. If the patient produces an inflammatory response (e.g. Wheal and Flare), then the patient is identified as sensitized to the evaluated allergen. Skin prick test reactivity can be correlated with patient history to determine allergens to be included in patient vials formulated… read more

An aqueous extract containing 50% glycerin. Glycerin acts as both a stabilizing and bacteriostatic agent. Glycerinated extracts have a longer shelf-life, due to these stabilizing properties. In high concentrations, glycerin has been reported to c

sed by a systemic (full body) allergic response. One or more of the following symptoms may occur: sneezing, mild to severe generalized urticaria, itching (other than at the skin test site), extensive or generalized edema, wheezing, asthma, dyspnea, cyanosis, hypotension, syncope, and upper airway obstruction. Symptoms may progress to shock… read more

A major allergen contained in short ragweed pollen. Short ragweed extracts are labeled with AgE concentrations (now called Amb a 1) The concentration of AgE (i.e., Amb a 1) is measured for each manufactured lot of extract, using a standardized assay. Clinical studies have been conducted, which established a therapeutic dose range for Ragweed allergy… read more
