Question 1

The ability of a test to detect a disease if it is present

Answer 1

Sensitivity

Question 2

A __________ test is a test that has a high liklihood of disease detection and a low likelihood of false negative.

Answer 2

Sensitive

Question 3

Sensitive tests have a (high/low) negative predictive value

Answer 3

High

The more sensitive a test, the less likely an individual with a negative test will have the disease and thus the greater the negative predictive value.

Question 4

Low (sensitivity or specificity) describes a test that is subject to false positive errors

Answer 4

Low specificty

Question 5

High (sensitivity or specificity) is required in order to confirm a diagnosis

Answer 5

high specificity

Question 6

What do we mean by SPIN and SNOUT?

Answer 6

SPIN, highly SPecific tests help rule IN a disease
A positive specific test is telling of a diagnosis
POSITIVE SPIN= you have the disease

SNOUT, highly SeNsitive tests help rule OUT a disease
A negative sensitive test is telling of not having the disease
NEGATIVE SNOUT=you dont have the disease

Question 7

A test is sensitive if it has a high liklihood of _______________

Answer 7

disease detected and therefore a low liklihood of a false negative

Question 8

Tests that are (specific or sensitive) have a high liklihood of disease detection

Answer 8

sensitive
