Carbon emissions associated with antenatal testing for hepatitis B prophylaxis eligibility, the Gambia.

Objective: To estimate the carbon footprint of three diagnostic strategies to identify pregnant women eligible for antiviral prophylaxis to prevent hepatitis B vertical transmission in the Gambia. Methods: e) ± uncertainty. Findings: e). Conclusion: Our findings suggest that HBcrAg rapid diagnostic tests can reduce emissions substantially compared with point-of-care PCR. Our study demonstrates that life cycle assessments are feasible in resource-constrained settings and highlights the importance of integrating sustainability into hepatitis B diagnostic strategies.
