i see lots of small labs around the city. i used to use "moms laboratory" near the park downtonw. results in two hours. i changed from them because they started requiring a doctors prescription before they would do testing. as of now ace will do it on your request and give you the results so i prefer that. there is always some question of the quality of "mom and pop" shops however i never had any suspicions about moms. moms also have a fairly limited menu to choose from. one of the nice things about the phils is that when i go see a doctor, that is my second opinion. i make my first using google and local labs and then see if the doctor agrees with me!
