Noninvasive Swansea criteria are valuable alternatives for diagnosing acute fatty liver of pregnancy in a Chinese population.

Background: This study aims to assess the diagnostic and prognostic value of Swansea criteria in diagnosing acute fatty liver of pregnancy (AFLP) in a Chinese population.

Methods: A retrospective study was conducted on 52 Chinese women diagnosed with AFLP. All selected cases were reassessed using the Swansea criteria with special focus on the noninvasive criteria, since performing a liver biopsy for this indication is rare in a Chinese population.
