Pregnancy tests in Mumbai

Hi, I need to know what is the procedure for getting a pregnancy test done in any pathology lab in Mumbai? My best friend thinks she might be pregnant and she needs to get one done without her parents knowing, so I basically want to know whether we need any doctor's prescriptions or provide personal information to get a pregnancy test done.

Also, are the home pregnancy tests reliable? Which one is the best and most reliable? And how much does the lab pregnancy test and a home pregnancy test kit would cost?

I really appreciate any help.

Thanks.

It is better if she is tested with a Gynaec. She also needs to speak to her partner as it is better if he accompanies her.
She will have to think very clearly wrt to what her options are if she is pregnant.
I am not sure how good the home pregnancy test are at the moment as I have not been in India for a long time.
All the best!
