What is the test for admissibility of testimony in a personal injury case?

reliable, disputes over admissibility must generally be left to the trial court's sound discretion. (People v. Montiel (1993) 5 Cal.4th 877, 918-919.) However, the trial court was not given the opportunity to exercise discretion here, however, because as respondent notes, Richmond did not object to this testimony in the trial court.
