Proposed Swansea diagnostic criteria for the diagnosis of acute fatty liver of pregnancy [49].

Nausea/vomiting	Leukocytosis (>11×106/L)
Abdominal pain (mainly epigastric)	Elevation in serum ammonia (>47 mmol/L)
Polydipsia/polyuria	Elevated transaminases (>42 IU/L)
Encephalopathy	Ascites or bright liver on ultrasound
Elevated bilirubin (>14 mmol/L)	Renal failure (creatinine >150 mmol/L)
Hypoglycemia (<4 mmol/L)	Coagulopathy (PT >14 s or APTT >34 s)
Elevated uric acid (>340 mmol/L)	Microvesicular steatosis on biopsy

PT – prothrombin time; APTT – activated partial thromboplastin time.
