Hi Muskan,
If you're opting for B.Sc. Lab technician in SN Medical College, Jodhpur you will have to give the college's entrance exam as this course isn't among the Ayush courses so NEET isn't valid for it. Get in contact with the college management office and get the information about their admission process. I don't think you'll need any other exam than the entrance exam and 50% marks in 12th board.
Thank you and good luck.
