or 968.38 (4)
are not admissible during the course of a civil or criminal action or proceeding or an administrative proceeding, as evidence of a person's character or a trait of his or her character for the purpose of proving that he or she acted in conformity with that character on a particular occasion unless the evidence is admissible under s. 904.04 (1)
or 904.05 (2)
and unless the following procedures are used:
The court may determine the admissibility of evidence under this section only upon a pretrial motion.
Evidence which is admissible under this section must be determined by the court upon pretrial motion to be material to a fact at issue in the case and of sufficient probative value to outweigh its inflammatory and prejudicial nature before it may be introduced at trial.
The results of a test or tests under s. 938.296 (4)
or 968.38 (4)
and the fact that a person has been ordered to submit to such a test or tests under s. 938.296 (4)

When evidence which is admissible as to one party or for one purpose but not admissible as to another party or for another purpose is admitted, the judge, upon request, shall restrict the evidence to its proper scope and instruct the jury accordingly.
