Dizziness is one of the most common complaints among patients admitted to the emergency department (ED). In most cases, the etiology remains unclear. Dizziness has a broad differential diagnosis. The initial symptoms of ALD can include many general complaints. The diagnosis of acute liver dysfunction (ALD) can usually be made by initial symptoms, physical examination, and biochemical tests, including liver function tests (LFTs) with high sensitivity and specificity. LFTs include albumin, bilirubin, coagulation factors (Activated Partial Thromboplastin Time (aPTT) and International Normalized Ratio (INR)), and liver enzymes, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphates (ALP), and y-glutamyl transpeptidase (GGT), which are marker of hepatic damage. Aim of this study is to investigate whether SOD is a symptom of ALD, the necessity of LFTs for patients with SOD in the ED, and a cost analysis of LFTs.
