ラボテストを科学的に検討することを学生に教える方法

How to Teach Students to Make Scientific Assessments of Laboratory Tests

　ラボテストの評価は，常に行わねばならない．"このテストは我々の持っている種々の技術が必要である"と問いかけて学生を励ますべきである．実際に，この問題に解答を与えることのできる，二つの特別の例を示そう．

　学生に，弱いK抗体を与え，抗ヒトグロブリンは与えない．学生は直ちにクームステストは，生死の問題にかかわることを知る．

Evaluation of laboratory tests should go on all the time. The student should be encouraged to ask, "Why do we need this test ^*1in our bag of tricks ?" There are two really spectacular places this question can be answered.

^*2Give the student a weak Kell antibody but do not give him any antihuman globulin. He learns very quickly that a Coombs test may make the difference between life and death.

^*3The second place is in bacteriology. Give him a broth culture, tell him it contains, among other things, Salmonella. But only give him blood plates to work with. He soon learns that without differential media the task is nearly impossible.
