2024年12月21日 · Sensitivity is a measure of how well a given test identifies the disease or trait in question (i.e., how well it avoids false negatives), while specificity is a measure of how well a given test identifies the absence of the condition being tested (i.e., how well it …

2018年6月30日 · Sensitivity is the percentage of true positives (e.g. 90% sensitivity = 90% of people who have the target disease will test positive). Specificity is the percentage of true negatives (e.g. 90% specificity = 90% of people who do …

Sensitivity: the ability of a test to correctly identify patients with a disease. Specificity: the ability of a test to correctly identify people without the disease. True positive: the person has the disease and the test is positive. True negative: the person does not …

2021年4月18日 · Sensitivity is the ability of a test to correctly identify those patients with the disease. It is also known as the True Positive Rate (TPR), i.e. the percentage of sick persons who are correctly identified as having the condition. Therefore sensitivity is the extent to which actual positives are not overlooked.

2025年1月22日 · In medical terminology, a test that correctly identifies people with a certain disease (“positive” result) has a high “sensitivity.” In other words, it finds almost all people with the disease. A test that correctly identifies people who don’t have the disease (“negative” result) has a high “specificity.” That means the test result is usually only abnormal if the person ...

2023年8月3日 · In medical tests, sensitivity is the extent to which actual positives are not overlooked (so false negatives are few), and specificity is the extent to which actual negatives are classified as such (so false positives are few).

2024年12月16日 · Sensitivity measures a test’s ability to identify true cases of a disease. Specificity measures a test’s ability to identify those without the disease. What Does Sensitivity Mean? Sensitivity refers to a test’s ability to correctly identify those with the condition.
