Serum ammonia does not guide management and is overutilised in patients with cirrhosis in hospital settings.
Hannah N, Vasic D, Kansal A, Al-Ani A, Hebbard G, Sood S. Hannah N, et al. Intern Med J. 2023 Nov;53(11):2057-2064. doi: 10.1111/imj.16053. Epub 2023 Apr 3. Intern Med J. 2023. PMID: 36891668
In cirrhotic patients, the sensitivity and specificity for serum ammonia and diagnosis of hepatic encephalopathy were 75% and 52.3% respectively. CONCLUSION: We affirm the poor utility of serum ammonia levels for guiding management of hepatic encephalo …

Serum ammonia as an early predictor of in-hospital mortality in patients with glufosinate poisoning.
Lee J, Lee Y, Kim YS, Choi JG, Go TH, Kim H, Cha YS. Lee J, et al. Hum Exp Toxicol. 2019 Sep;38(9):1007-1013. doi: 10.1177/0960327119855124. Epub 2019 May 30. Hum Exp Toxicol. 2019. PMID: 31146590
Data were collected from consecutive patients diagnosed with glufosinate ammonium poisoning between May 2007 and February 2018. The initial serum ammonia level was defined as the highest serum ammonia level measured within 12 h after emergency departme …
