Test Validation
Cards in this deck (23)
- 1What are the 5 measures to compare information?Sensitivity, Specificity, Positive Predictive Value, Negative Predictive Value, Accuracy
- 2Sensitivity = ?The ability of a test to detect a disease
- 3Sensitivity formula = ?TP/TP+FN
- 4Specificity = ?The ability of a test to identify normality
- 5Specificity formula = ?TN/TN+FP
- 6Positive Predictive Value = ?The % of non-invasive tests which accurately predict abnormality
- 7Positive Predictive Value formula = ?TP/TP+FP
- 8Negative Predictive Value = ?The number of non-invasive tests which accurately predict normality
- 9Negative Predictive Value formula = ?TN/TN+FN
- 10Accuracy = ?The overall % of correct non-invasive diagnoses(How well you rule out disease)
- 11Accuracy formula = ?TP+TN/TP+FP+TN+FN
- 12The 2x2 box configuration that allows you to calculate the statistics is called the?Chi square
- 13What the Chi square looks like.
- 14This means that both non-invasive and gold standard found diseaseTrue Positive(TP)
- 15This means that the non-invasive result was abnormal, but the gold standard was normal.False Positive(FP)
- 16This means that the non-invasive exam was normal, but the gold standard found disease.False Negative(FN)
- 17This means that the non-invasive and the gold standard agree on the absence of disease.True Negative(TN)
- 18If there is a "G" in front of the positive/negative predictive values, what does it stand for?Group
- 19What is the main accrediting body for vascular labs?ICAVL
- 20ICAVL stands for?Intersocietal Commission for the Accreditation of Vascular Laboratories
- 21This 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
- 22True/False Participation in the accreditation process is voluntary.True
- 23The ICAVL offers accreditation in what 5 areas?Extracranial Cerebrovascular, Intracranial Cerebrovascular, Peripheral Arterial, Peripheral Venous, Visceral Vascular
