Lab finder: therascreen PIK3CA test – the companion diagnostic for PIQRAY (alpelisib)


  • Main Image Navi
Companion diagnostics analyze a patient's DNA or RNA for actionable genetic alterations in order to help determine what treatment options may be best. Companion diagnostics are:
  • FDA-approved for IVD use
  • Sensitive tests that are clinically validated for specific targeted therapies for specific cancers

The therascreen PIK3CA RGQ PCR Kit is a companion diagnostic test for use as an aid in identifying patients with advanced breast cancer for whom treatment with PIQRAY (alpelisib) may be appropriate.

The kit is a qualitative assay that can yield results in less than two working days.
