my wife is in proccess to get green card some of that requier medical tests, there is a list of clinics who do that, one of them is valley medical center in granada hills, we ask on the phone how much is a TB test, they said $60, minimum, we wnt to another lab they charge $25, with that test we went to valley medical center and start all the other paper work, the DR, Duck Lim didn't like it, so he said that she need XR cuz he think that lab who did the test is wrong, he did the XRAY test and find that he is wrong, but still he charge us with $80. even that he the one who did the mistake, keep away from him
