Hello,

Yes you can be a lab technician. After completing 12th, you can choose bachalor of medical laboratory technician course or BMLT. Which is for 3 years course. For this study you can't give NEET examination..some colleges are offered merit based admission. Some colleges are offered their own college entrance examination and some colleges are offered state entrance examination. So you have to check which college you will study for this college..after that the basis of college admission you can study for entrance examination.

All the best.
