The Positive Likelihood Ratio (LR+) is a measure of how much the odds of having the disease increase when a test is positive. It is calculated as Sensitivity / (1 - Specificity). An LR+ of 10, for example, means a positive test result is 10 times more likely to be seen in a person with the disease than in a person without it. It is a useful single number that combines sensitivity and specificity to quantify the diagnostic impact of a positive test result.
