thyroid hormones regulate the metabolisms of all cells including hepatocytes, and hence, modulate hepatic function. hyperthyroidism is one of the most common endocrine disorders characterized by increased secretion of thyroid hormones t3 and/or t4. this study investigated frequency of abnormal liver function tests in the patients with hyperthyroidism that referred to imam reza hospital of kerma...

Both total and direct bilirubin measure the formation of azobilirubin, which is detected at 570/660 nm. The total bilirubin reaction contains surfactant and caffeine, which solubilize “indirect” bilirubin and accelerate the reaction (1). Direct bilirubin is a component of total bilirubin and therefore should always be smaller in value. The presence of a monoclonal immunoglobulin (2220mg/dL) fal...

We present a modified Evelyn-Malloy method, adapted to the Abbott Biochromatic Analyzer (ABA-100) for the determination of both total and direct bilirubin. It requires less than 25 mul of serum or plasma. At least 50 samples can be assayed per hour with economy of reagent consumption and the precision compares favorably with that for conventional manual methods.

BACKGROUND Delayed diagnosis of biliary atresia is an important cause of pediatric end-stage liver failure and liver transplantation. We sought to determine whether direct bilirubin is underutilized by retrospectively reviewing patients with biliary atresia. Further, we aimed to determine the role of reflex testing for direct bilirubin in patients suspected for jaundice. METHODS The time inte...

A method for the determination of both direct and indirect serum bilirubin on the AutoAnalyzer is described which has a number of advantages over the automated method that is currently recommended. It gives total bilirubin results which are similar to those obtained with the equivalent manual method and direct bilirubin results which are usually about 10% lower.The effect of haemolysis on estim...

background: neonatal jaundice is clinically presented in 60% of full-term newborns. about 8% of newborns with jaundice have urinary tract infection (uti) without any other clinical signs in favor of uti. in present study we evaluated clinical and paraclinical data that help to rapid and early diagnosis of uti in apparently healthy newborns with jaundice.   methods: from february to august 2006,...
