Higher specificity and sensitivity than current methodologies1

Less specimen required

More accurate, reproducible results

  • LC/MS/MS is a clinical and scientific innovation, which is setting the standard of testing and patient care
  • Important for pediatric and difficult draws
  • No cross-reactivity with other steroid hormones
  • More accurate and reliable results at lower concentrations
  • The broadest LC/MS/MS test menu, featuring tests frequently ordered:
