Final answer:
To find the sensitivity, specificity, positive predictive value, and negative predictive value of test T, we calculate the ratios between the true positive, true negative, false positive, and false negative results.
Step-by-step explanation:
To find the sensitivity, specificity, positive predictive value, and negative predictive value of test T, we need to calculate the ratios between the true positive, true negative, false positive, and false negative results. For test T, we have:
- True positive: 138
- False positive: 24
- Total positive (bị tiểu đường): 150
- False negative (không bị tiểu đường): 0
- Total negative: 150 - 138
Sensitivity (độ nhạy) = true positive / true positive + false negative
Specificity (độ chuyên) = true negative / true negative + false positive
Positive predictive value (dương giả) = true positive / true positive + false positive
Negative predictive value (âm giả) = true negative / true negative + false negative
