In brief: Multiple
There are many because the causes of urticaria are many.
Some of the tests are actually physical stimuli (temperature, vibration, etc). Most others will involve skin prick or blood testing: cbc, cmp, ana, esr, crp, tsh, food ige, total ige, just to name a few... This is generally very low yield though. A good allergist will help you sort through all the options.
