Correct!

The appearance of a wheal and erythema, with a wheal diameter at least 5 mm greater than that produced by the control, indicates a positive response in an intradermal skin test. A localized itchy wheal would be a positive response for a prick test. Papules and ulceration would be a positive response for a patch test.
