Regarding TB test, since Feb 2013, new applicants in the Philippines must include a TB test certificate/result from an accredited clinic of UKBA. If your wife didn't need that when she submitted the applications, she can get a TB test from the accredited clinic of UKBA because she would be asked upon entry to UK. http://www.ukba.homeoffice.gov.uk/countries/philippines/applying/tb-test/?langname=UK%20English
