Question | Answer |
What are the 5 measures to compare information? | Sensitivity, Specificity, Positive Predictive Value, Negative Predictive Value, Accuracy |
Sensitivity = ? | The ability of a test to detect a disease |
Sensitivity formula = ? | TP/TP+FN |
Specificity = ? | The ability of a test to identify normality |
Specificity formula = ? | TN/TN+FP |
Positive Predictive Value = ? | The % of non-invasive tests which accurately predict abnormality |
Positive Predictive Value formula = ? | TP/TP+FP |
Negative Predictive Value = ? | The number of non-invasive tests which accurately predict normality |
Negative Predictive Value formula = ? | TN/TN+FN |
Accuracy = ? | The overall % of correct non-invasive diagnoses(How well you rule out disease) |
Accuracy formula = ? | TP+TN/TP+FP+TN+FN |
The 2x2 box configuration that allows you to calculate the statistics is called the? | Chi square |
What the Chi square looks like. |

|
This means that both non-invasive and gold standard found disease | True Positive(TP) |
This means that the non-invasive result was abnormal, but the gold standard was normal. | False Positive(FP) |
This means that the non-invasive exam was normal, but the gold standard found disease. | False Negative(FN) |
This means that the non-invasive and the gold standard agree on the absence of disease. | True Negative(TN) |
If there is a "G" in front of the positive/negative predictive values, what does it stand for? | Group |
What is the main accrediting body for vascular labs? | ICAVL |
ICAVL stands for? | Intersocietal Commission for the Accreditation of Vascular Laboratories |
This signifies that a facility has been reviewed by an independent agency, which recognizes the commitment to quality testing for the diagnosis of vascular disease. | Accreditation |
True/False Participation in the accreditation process is voluntary. | True |
The ICAVL offers accreditation in what 5 areas? | Extracranial Cerebrovascular, Intracranial Cerebrovascular, Peripheral Arterial, Peripheral Venous, Visceral Vascular |
