BSc MLT & BSc Forensic Sciences  both are very good courses. Among this two fields, I would say Forensic science will need higher education i.e., a MSc is required to get a job. Also in forensic science there is a very few companies and organization as well as government jobs in the forensic. But if you go for MLT, then you will have larger scopes i.e., in hospital setups, Pathology labs etc. Thus if you have some patience and if you wish to go for higher studies then go for Forensic Science. If you wish to get job after BSc or you want to go for a course with more job sectors then go for MLT.

Now BSc Biochemistry is also a very good field of study. The field have very good employability in pathology labs and R&D in Biopharm. But for this field you must have a MSc to get good positions. Now in companies like Abbott, Cipla they used to take PhD Biochemists. So depending on your interest you should choose this course. If you are wiling to go for higher education then you can choose it and I would say you will not be left unsatisfied.
