The similarity of work is evident but with different types of objects. Both types of techs are trained with primary college/university education supported by on-the-job training by peers to perform repetitious work. However, one of the techs is generally categorized as a scientist. It is unclear why this is so when they obtain no learning and/or training in science (link).
This discrepancy in training and claim of the techs causes hindrance in addressing illnesses and their evaluation (testing) such as virus-based, in particular COVID-19. Therefore, the hospital techs, such as physicians, should seek help from trained scientists to isolate and identify the “bugs” (so-called pathogens or poisons/chemicals).
It is hoped that authorities will consider this suggestion with an open mind and without hostility.
