[{'content': 'If a  biochemical  test  gives  the  same  reading  for  a  sample  on  repeated testing, it is inferred that the measurement is: \nSelect and explain. \nA. Precise, B. Accurate, C. Specific, D. Sensitive', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Criteria of screening test\n\nAcceptability – The test should be acceptable to population to which it is going to be applied.\nRepeatability\xa0 (reliability,\xa0precision,\xa0reproducibility)\xa0 –\xa0 The\xa0test\xa0must\xa0give consistent results when repeated more than once on the same individual or material under the same condition.\nValidity (accuracy) – It refers to what extent the test accurately measures which it purports to measure. (it means it expresses the ability of a test to separate or distinguish those\xa0who\xa0have\xa0the\xa0disease\xa0from\xa0those\xa0who\xa0do not). Accuracy refers to closeness with which measured values agree with “true” value.\n\nIt has two components:\ni. Sensitivity – Ability of test of identify correctly all those who have disease.\nii. Specificity – Ability to test to identify correctly all those who do not have disease.\xa0\nSo, if test\xa0gives the same\xa0reading\xa0for\xa0a\xa0sample\xa0on\xa0repeated testing means test is precise (i.e., reliable, reproducible, repeatable).', 'role': 'assistant'}]
