Hi dear,
           B.Sc. in Medical Laboratory Technology is a 3 year undergraduate course, eligibility to which is qualifying 10+2 Level with minimum of 55% marks.
Some best colleges conduct the admission test for the admission in this course. It depends on one institute to other.Most colleges or institutes offering the program admit candidates based on skills and performance in a relevant entrance exam, often followed by a round of personal interview, wherein their general aptitude for the program is tested.

Whereas Some institutes provide direct admission based on the applicant performance at the 10+2 level. Asian Institute of Health Sciences, Hindustan College, Oasis Institute of Health Sciences & Research Centre, School of Health Sciences and Sharda University are few such institutes.

All the best
