What is the effect of scientific "test" in the context of medical malpractice cases?

⁶ Presumably, Defendant is referring to the admonition in People v. Leone, 25 N.Y.2d 511, 518, 307 N.Y.S.2d 430, 255 N.E.2d 696 (1969) that scientific "tests" can have an undue influence on juries and therefore, courts must be "most careful in admitting into evidence the results of such tests unless their reasonable accuracy and general scientific acceptance is clearly recognized."
