Flashcards in Week 4 Deck (16):

1

## If a diagnosis test has high sensitivity, what does that mean?

### it has few false negatives

2

##
True or False:

-- NPV is the likelihood of not having a disease when a test is negative?

### True

3

## What tells you how likely a test result is to be found?

### likelihood ratio

4

## A highly specific test is effective in ruling conditions "in" or "out" and why?

### in, because it has few false positives

5

##
True or False:

-- If a patient is very unlikely or very likely to have a disorder, there is probably no need for test?

### True

6

## What is the probability that a person WITH disorder will have a positive test result?

### Sensitivity

7

## What is the probability that a person WITHOUT disorder will have a negative test result?

### Specificity

8

## Ability of a Dx test to identify true disease without missing anyone who has it?

### sensitivity

9

## Ability of a Dx test to identify absence of disease without mislabeling anyone who does not have it?

### specificity

10

## What type of test has few false negatives so it is effective at ruling conditions "out"?

### SnNout (sensitivity)

11

## What type of test has few false positives so it is effective at ruling conditions "in"?

### SpPin (specificity)

12

## Existing cases of a disorder in a population at one point in time?

### prevalence

13

## The likelihood of having the Dx when the test is positive?

### Positive Predictive Value (PPV)

14

## The likelihood of not having the Dx when the test is negative?

### Negative Predictive Value (NPV)

15

## A LR > 10 is good for ruling the condition....

### IN
