What changed between versions

Engrossed Enrolled · 2 edits · Jul 31, 2026
MINOR
The bill text was finalized for the official enrolled version, removing the 'Engrossed' label to indicate it is ready for the Governor's signature. A minor technical edit was made to a definition of 'biomarker testing' by removing the phrase 'expression whole exome' from a list of covered tests. This change does not alter the bill's scope, funding, or eligibility criteria, as the remaining listed tests (such as whole genome and transcriptome sequencing) still fully cover the intended medical applications.
DEFINITION

The definition of 'biomarker testing' was slightly edited to remove 'expression whole exome' from the list of included tests, though the overall scope of covered testing remains broad.

TECHNICAL

The document header was updated from 'Engrossed' to 'Enrolled' to reflect the bill's final status before becoming law.
