Overview of MS Flashcards
The probability of the target condition being present before the results of a diagnostic test are available is described as
a. pretest probability
b. posttest probability
c. test threshold
d. treatment threshold
pretest probability
The probability of the target condition being present after the results of a diagnostic test are available is described as
a. pretest probability
b. posttest probability
c. test threshold
d. treatment threshold
posttest probability
The probability above which a clinician dismisses a diagnosis and orders no further tests
a. pretest probability
b. posttest probability
c. test threshold
d. treatment threshold
test threshold
The probability above which a clinician would consider a diagnosis confirmed and would STOP testing and initiate treatment
a. pretest probability
b. posttest probability
c. test threshold
d. treatment threshold
treatment threshold
If the pretest probability is high enough to test for, but not at the treatment threshold, testing will be best if the test moves the probability across either __
threshold
the more possible adverse effects of treatment, the _ treatment threshold should be set
higher
