Used for diagnostic testing of clam allergies via skin prick testing, and may be used as part of allergen immunotherapy (desensitization treatment) for individuals with confirmed clam allergies experiencing symptoms such as hives, itching, or anaphylaxis upon exposure.

Contains trace amounts of clam protein antigens that trigger an immune response when introduced to the skin or body. In diagnostic use, it elicits a localized allergic reaction if antibodies are present. In immunotherapy, repeated controlled exposure aims to desensitize the immune system over time.

Should only be administered by healthcare professionals trained in allergenic extract therapy with emergency equipment available. Not suitable for patients with uncontrolled asthma, severe cardiac conditions, or those taking beta-blockers. May cause systemic reactions including anaphylaxis. Dosage and administration protocols must be individualized.
