UW HSIP- Subsequent HepB Repeat Titer

1 min. readlast update: 10.22.2025

Please complete a repeat Quantitative Hepatitis B Surface Antibody (HBsAb-Qn) Titer 1 month after your additional HepB dose date and submit the full lab report for approval. A titer is a lab test requiring a blood draw to determine immunity status.  An accredited healthcare provider's order must be obtained to get the titer.

If your repeat titer is non-reactive/negative, please submit the full lab report for approval. Once approved, a subsequent HepB requirement tag will be created to inform you of your next steps for the HepB requirement.   

If you have questions, please contact HSIP at myshots@uw.edu.
