What PT material does the CAP offer for HER2 testing?
HER2 by Immunohistochemistry (IHC) Survey (HER2) The HER2 Survey is an IHC Survey that provides 20 challenges, one tissue microarray slide consisting of 10 cores and 10 online image challenges, twice per year. Enrollment in the HER2 Survey will satisfy LAP requirements for participation in an accepted PT program for HER2 by IHC. HER2 by Fluorescence in situ Hybridization (FISH) Survey (CYH) CYH is a FISH Survey that provides 10 challenges, twice per year. Enrollment in the CYH will satisfy the LAP requirement for participation in an accepted PT program for HER2 by FISH, interpretation and hybridization onsite activity. Laboratories that do interpretation only must perform alternative assessment. HER2 by Brightfield in situ Hybridization Survey (ISH2) The College introduced this new program (2008) that will satisfy biannual PT requirements in 2010.
