contrast study in CT scan

I just want to know if others do skin/allergy testing before doing a contrast study in CT scan even if a hypoallergenic/non-ionic contrast agent will be used?
We don't do anything unless they have a known allergy.

Why would you?

As with your other post regarding allergy testing prior to giving antibiotics, it would appear that some practices in your country are significantly different from common practice in the U.S.We do use a protocol with inpatients with documented allergy to iodides who need a non-emergent CT scan - it's a 16-hour regimen of pre-medication with steroids and diphenhydramine prior to the scan.

No we do not. We do the same thing Altra does except it is a 13 hour protocol instead with the same meds.
