Question 1

What is sensitivity in clinical terms?

Answer 1

Sensitivity is the ability of a test to correctly identify those with the disease (true positive rate).

Question 2

What is specificity in clinical terms?

Answer 2

Specificity is the ability of a test to correctly identify those without the disease (true negative rate).

Question 3

Answer 3

False. Sensitivity is related to ruling out a disease.

Question 4

Question 5

Which of the following is more important in ruling out a disease: Sensitivity or Specificity?

Answer 5

Sensitivity

Question 6

Which of the following is more important in ruling in a disease: Sensitivity or Specificity?

Answer 6

Specificity

Question 7

Give a clinical example where high sensitivity is crucial.

Answer 7

Screening for breast cancer to ensure minimal false negatives.

Question 8

Give a clinical example where high specificity is crucial.

Answer 8

Confirmatory testing for a rare disease to avoid false positives.

Question 9

What does it mean if a test has a HIGH SENSITIVITY?

Answer 9

A HIGHLY SENSITIVE TEST if NEGATIVE rules OUT the disease

LOW FALSE NEGATIVE = HIGH SENSITIVITY

Question 10

What does it mean if a test has a HIGH SPECIFICITY?

Answer 10

a HIGHLY SPECIFIC TEST if POSITIVE rules IN the disease

LOW FALSE POSITIVE = HIGH SPECIFICITY

Question 11

Which type of test is best for SCREENING

Answer 11

Sensitivity has a LOW FALSE NEGATIVE… if negative you for sure DO NOT HAVE IT

Question 12

Which test is better for confirming a disease

Answer 12

Specificity if positive you most likely have the disease because a HIGH SPECIFICITY has a LOW FALSE POSITIVE
