2. One of the routine procedures performed by a laboratory technologist working in a clinical
chemistry laboratory is preparation of working solutions. Accordingly, the technologist needs
to prepare ALT (GPT) working solution by mixing 4 part from reagent 1 (R1) and I part
from reagent 2 (R2). He needs to prepare 1 ml of this working solution for the test
What will be the proportion of R1 and R2 in the solution respectively?
(A) 200 µl and 800 al
(B) 400 μl and 600 μl
(C) 600 μl and 400 pl
(D) 800 μl and 200 μl
