Hello,

We would like to get input from the LOINC community regarding the FLT3-ITD test mapping granularity.

We have a local test reporting FLT3-ITD mutation detected and another local test reporting the FLT3-ITD mutation detected in exon 14 and 15 (1). We know that FLT3-ITD mutation can be detected in exon 11& 12 (2) from publications. Should we create 2 local LOINC codes\* for exon specific and non-specific tests?

- LOINC has no office code for FLT3-ITD test at this moment yet.

Regards,

Jo SHUM
