just went for the health screening in the morning. its a breeze that everything was completed within 20mins. for those who are considering health screenings, you may want to consider ntuc healthcare as its fast and reasonably priced. by the way i did mine at the toa payoh branch.
i'll strongly discourage raffles medical (north bridge road) as i went for 2 pre-employment screening before and on both occassions the whole process took almost 3 hours, where 2.5 hours i'm waiting and waiting and waiting.. in addition they are quite pricey...
another good option is sata. their package is very comprehensive and its effective even though the crowd is there. raffles medical certainly has alot to learn.
by the way the results will be out within 3 days. just pray that everything turns out fine.
