I went to this clinic for a TB test and the way they have it set up, you only have one day to go back for the reading when in fact the reading time is 48 to 72 hours so if you get the test on Monday you should have a choice to go back for the reading on Wednesday or Thursday, but they don't do any TB tests or reads on Thursdays so that forces everyone to get their reading on one day only. If you're busy and can't make it on that day you have to pay for the second test yourself! This policy makes no sense for the patients but apparently a lot of sense for them because they make twice the money! This is not a good place to go for TB tests for this reason. There are other clinics that do them for free or nominal fees. Check them out.
