This whole system is a joke. I was give an appt at a certain time. Went in and my appt was scheduled for a different location. Luckily they had an opening 10 mins later. Then I got a call than the clinic where my tb test needed to be read was going to be closed. They gave me another appt. went there and the guy didn't want to read it because i was 50 mins earlier from the 48 hrs. Because "I could have a damn reaction in 50 mins".
