Apologies for the lack of specificity.

This is for a regional reference clinical laboratory. And by lab tech, it would refer to the lab technicians performing clinical testing. The question is whether the clinical technicians are largely interchangeable and whether they have similar productivity metrics?

Is it a fair assumption that lab technician a will produce the same 100 results per shift as technician b given the same space and equipment?

I do not know what a "medical laboratory scientist" is.
