A » In medical testing, a false positive occurs when a test indicates the presence of a condition or disease when it is not actually present, leading to unnecessary stress and treatments. Conversely, a false negative is when a test fails to detect a condition that is present, potentially delaying crucial treatment. Accurate testing aims to minimize both false positives and false negatives to ensure reliable diagnosis and patient care.
