Medical Test:-
1.
Medical test took place in Bhabha
hospital. They brought us(13 ppl) to hospital by buson 8am
2.
. They took Urine sample first then
blood
3.
.In radiology section they took
X-ray of chest.
4.In Physical test(Be careull5.All medical test were done
abt 4 pm so it took very long time.
6. Then we were told to leave .
7. If somebody's medical test is doubtful he has to stay for
further chekup or if herequired checkup on diet he\she has to come in next morning
