Update to PAP-HPV Reflexing Algorithm

The algorithm that reflexes HPV testing off the PAP Test (LAB1230097) when the “HPV Reflex” option is selected during PAP ordering will no longer include pregnancy status as a criterion for reflexing on LSIL patients. Prior to this update, if HPV Reflex was selected, a PAP Diagnosis of LSIL on patients 25 and older would only reflex HPV testing if the patient was non-pregnant. Starting 11/6/2024, if HPV Reflex was selected, a PAP Diagnosis of LSIL on patients 25 and older will reflex HPV testing regardless of pregnancy status. This update aligns with current ASCCP Risk-Based Management Consensus guidelines.

Holiday routes are built around this information, a STAT courier will be available.
