He might take sputum test. What happened to my mother are as follow medical May 30, 2014 twice chest xray, June 2, 2014 pulmo eval at St Lukes Ermita referred by St Luke's Global and sputum test June 4, 5 and 6. After a week you need to go back for smear result if negative then repeat chest xray on date provided by St Luke's on a pc of paper and ours dated Sept 1, 2014 if culture test turn negative. St Luke's never instruct my sis and mother to call them or they will call us only instructions was if we receive letter from Canadian Embassy before Sept 1, 2014 they need to bring that letter asap to St Luke's. We paid pulmo eval 1,600+, plus 2,625 for sputum test and 5,588 for additional fee for sputum studies all in php.
