MLT ASCP PRACTICE TEST QUESTIONS BOARD PRACTICE 2023 LATEST SOLUTION UPDATE QUESTIONS AND ANSWERS 
 
The correct answer for this question is 1300 mg/dL. The laboratorian performed a 1:4 dilution by adding 0.25 mL (or 250 microliters) of patient sample to 750 microliters of diluent. This creates a total volume of 1000 microliters. So, the patient sample is 250 microliters of the 1000 microliter mixed sample, or a ratio of 1:4. Therefore, the result given by the chemistry analyzer must be multipli...

Title: Reaction Chemistry 
Purpose: The purpose of this experiment is to observe various types of chemical reactions and 
their results which include six types of simple chemical reactions and reversible reactions. Also, 
to detect chemical changes, exothermic and endothermic reactions along with color change 
reactions and different reactions where precipitates form. The oxidation-reduction of methylene 
blue indicator is also performed to demonstrate the reversibility of a reaction.
