Sensitivity and Specificity Hybrid Class #4

Sensitivity is

• the proportion of time a diagnostic test is positive in patients who have the disease

• the proportion of time a diagnostic test is negative in patients who do not have the disease

• a characteristic of a test with a high false positive result

• a characteristic of a test with a low false-positive result

A test that may be useful for ruling out a disease when the test is negative

has a

• low sensitivity

• high sensitivity

• low specificity

the predictive value of a test is called

• current odds

• current probabilities

• anterior probabilities

• posterior probabilities

Specificity is

• the proportion of time that a diagnostic test is negative in patients who HAVE the disease

• a characteristic of a test with a high false-positive result

• the proportion of time that a diagnostic test is negative in patients who DO NOT have the disease

• the proportion of time that a diagnostic test is positive in patients who do not have the disease

A test that may be useful for ruling in a disease when the test is positive has a

• a test with low specificity

• a test with high specificity

• a test with high sensitivity

A positive result on a sensitive test with a low prevalence is

• enough to make a diagnosis

• followed by a more specific test

If the prior probability of a test is low

• a positive test may not be meaningful

• a positive test is very meaningful

• a positive test means a high probability of the disease

If a test has a high sensitivity, it has

• a low false positive rate

• a high false positive rate

• A low false negative rate

A test with a high specificity has

• a high false negative rate

• a low false-positive rate

• a high false positive rate
