Question

quantitative analysis of a blood sample is useful for all, except??

chlorpromazine

iron

acetaminophen

digoxin

Answer 1

Chlorpromazine. Purely because I work in a clinical chemistry lab and I've never heard of it. And we routinely measure the other three. Measuring iron is useful to find out whether someone is iron deficient or has iron overload. Acetaminophen is measured to see if someone has taken an overdose that needs treatment. Digoxin needs to be measured since there is a fine line between a therapeutic dose and a toxic dose.
