i was brought into the E.R. on 5-25-2012 suspected to be intoxicated. they ran the necessary tests, alcohol blood test, basic metabolic panel, EKG

electrocardiogram, EKG electrocardiogram B948 ( what''s the difference between the 2 i am not sure ), urine drug screen, headbrain w/o contrast. i don''t recall signing any consent forms do to the state i was in but they performed a hepatic function panel. i was in the hospital 2 other times that week and this was not performed and they did not need to perform this test to give me treatment. is this a test that was absolutely necessary for me to be given? and if it was necessary for it to be done then do i have a claim against the other hospital that didn''t perform this test before they treated me?
