Show Answer & Explanation ▾
Highly specific test, when positive, rules in a disease. Reference: Park’s Textbook of Preventive and Social Medicine, 25 th Edition, pg- 153
Screening is part of the Screening section of PSM. Practise 129 exam-style MCQs for NEET PG, FMGE, INI-CET and NEET SS, each with the correct answer and a detailed explanation.
Screening MCQs test whether candidates can handle sensitivity, specificity, predictive values and the rules that let a test rule a disease in or out — high-yield NEET PG biostatistics and a regular feature of PSM papers.

Sensitivity of a screening test is the ability of the test to identify correctly those who have the disease. It confirms that the person has the disease if the disease is common. Reference: Park’s Textbook of Preventive and Social Medicine, 25 th Edition, pg- 152
To determine the appropriate statement, let's define the terms: Positive Predictive Value (PPV): The probability that a person with a positive test result truly has the disease. Negative Predictive Value (NPV): The probability that a person with a negative test result truly does not have the disease. Sensitivity: The proportion of true positive cases that the test correctly identifies. Specificity: The proportion of true negative cases that the test correctly identifies. Given the information: True positives (TP): 180 True negatives (TN): 150 False positives (FP): 50 (200 - 150) False negatives (FN): 20 (200 - 180) Sensitivity=TP/(FN+TP)=180/(20+180)=180/200=0.9 = 90% Reference: Park’s Textbook of Preventive and Social Medicine, 25th Edition, pg- 152
NPV= TN/(TN+FN) x 100= 150/170 x 100= 88% Reference: Park’s Textbook of Preventive and Social Medicine, 25 th Edition, pg- 152
