What does fiorinal with codeine show up on a drug test?

Tylenol 4 has 1 more grain ov Codeine than fiorinal. Drug test put both medicines in an opiate category.

Tylenol 4 does not even contain 1 grain of codeine..it has 1/2 of a grain.Fiorinol is not codeine at all but a barbiturate, same as tuinol,seconol,nimbutol,and tuinol.A total different class of drugs.They will show up as different class of drugs.The above info is incorrect
