Test results may help make a diagnosis in symptomatic patients (diagnostic testing) or identify occult disease in asymptomatic patients (screening). If the tests were appropriately ordered on the basis of the clinical presentation, any results should assist in ruling in or out possible diagnoses.
When should a laboratory test be done?
A laboratory test should be done only if its results will affect management ; otherwise the expense and risk to the patient are for naught. Clinicians can sometimes make the determination of when to test by comparing pre-test and post-test probability estimations with certain thresholds. Above a certain probability threshold, benefits of treatment outweigh risks (including the risk of mistakenly treating a patient without disease), and treatment is indicated. This point is termed the treatment threshold and is determined as described in Clinical Decision-Making Strategies: Probability Estimations and the Treatment Threshold. By definition, testing is unnecessary when pre-test probability is already above the treatment threshold. But testing is indicated if pre-test probability is below the treatment threshold as long as a positive test result could raise the post-test probability above the treatment threshold. The lowest pre-test probability at which this can occur depends on test characteristics (eg, LR+) and is termed the testing threshold.
What is the specificity of a test?
Specificity is the likelihood that patients without the disease will have a negative test result in patients without disease (true-negative rate) Thus, a test that is negative in 9 of 10 patients without disease has a specificity of 0.9 (or 90%).
What is the ideal dichotomous test?
An ideal dichotomous test would have no false positives or false negatives; all patients with a positive test result would have disease (100% PPV), and all patients with a negative test result would not have disease (100% NPV). In reality, all tests have false positives and false negatives, some tests more than others.
What is LR in medical?
Unlike sensitivity and specificity, which do not apply to specific patient probabilities, the LR allows clinic ians to interpret test results in a specific patient provided there is a known (albeit often estimated) pre-test probability of disease.
What is the predictive value of a test?
For a given test, predictive values vary depending on the prevalence of disease in the patient population tested. Positive predictive value (PPV) is the proportion of patients with a positive test that actually have disease. Thus, if 9 of 10 positive test results are correct (true positive), the PPV is 90%.
What does sensitivity mean in medical terms?
Sensitivity represents how well a test detects the disease; a test with low sensitivity does not identify many patients with disease, and a test with high sensitivity is useful to exclude a diagnosis when results are negative.
