I took a 'cetrine' antihistamine at about 4pm on sunday and i have a skin prick allergy test today tuesdy at 5pm. am i still ok for the test?

Not likely: Cetrine (cetirizine in U.S.) is an excellent antihistamine and typically takes at least 3 days to be cleared from the body for allergy tests to be interpreted accurately without the antihistaminic effect interfering. Sometimes it takes even longer than 3 days.
