Quest Diagnostics hair-test data hints at DGX volume growth

Why it may matterVerify against the original reporting

Positive near-term signal from higher hair-test positivity and broader testing demand could lift DGX-related volumes and pricing. However, cannabis-regulatory shifts pose a regulatory risk that could constrain upside if federal testing mandates change. Historically, health services data releases tied to testing demand can move lab stock multiples modestly higher when peers’ volumes are prolonged or expanding.
