S-pass medical check-up

I am Muhammed Roshan from India. My S-pass application got approved before 2 days.  As per the information provided in the IPA which I have received, I need to take some medical tests. My employer had requested me to get the tests done in India itself. I would like to know whether I can get this test done in any of the clinics/laboratories in India and will it be considered valid by the Singapore MOM . Is there any criteria we should follow while choosing a clinic?

What tests do they say you need? The usual would be HIV blood test, and chest x-ray for TB.

When I did this the government site ICA? , MoM?, did state clearly who could accredit these tests ... have you checked that?

p.s. here, they only take take maybe two days from appointment to results...
