In a 2x2 diagnostic table, if the gold standard is positive and the clinical test is positive, this cell is called:

• A. True Positives
• B. False Positives
• C. True Negatives
• D. False Negatives

Answer: (A)

When evaluating a diagnostic test, the intersection where both the gold standard and the test are positive is a true positive. This means the test correctly identified someone who truly has the condition, as confirmed by the definitive standard. It’s the only cell where there is agreement on the presence of disease between the test and the gold standard. In contrast, a false positive would be test positive but the gold standard negative, a true negative would be both negative, and a false negative would be test negative but gold standard positive.
