Evaluation of Abnormal Liver Chemistries
ACG Clinical Guideline: Evaluation of Abnormal Liver Chemistries Paul Y. Kwo, MD, FACG, FAASLD1, Stanley M. Cohen, MD, FACG, FAASLD2, and Joseph K. Lim, MD, FACG, FAASLD3 1Division of Gastroenterology/Hepatology, Department of Medicine, Stanford University School of Medicine, Palo Alto, California, USA; 2Digestive Health Institute, University Hospitals Cleveland Medical Center and Division of Gastroenterology and Liver Disease, Department of Medicine, Case Western Reserve University School of Medicine, Cleveland, Ohio, USA; 3Yale Viral Hepatitis Program, Yale University School of Medicine, New Haven, Connecticut, USA. Am J Gastroenterol 2017; 112:18–35; doi:10.1038/ajg.2016.517; published online 20 December 2016 Abstract Clinicians are required to assess abnormal liver chemistries on a daily basis. The most common liver chemistries ordered are serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase and bilirubin. These tests should be termed liver chemistries or liver tests. Hepatocellular injury is defined as disproportionate elevation of AST and ALT levels compared with alkaline phosphatase levels. Cholestatic injury is defined as disproportionate elevation of alkaline phosphatase level as compared with AST and ALT levels. The majority of bilirubin circulates as unconjugated bilirubin and an elevated conjugated bilirubin implies hepatocellular disease or cholestasis. Multiple studies have demonstrated that the presence of an elevated ALT has been associated with increased liver-related mortality. A true healthy normal ALT level ranges from 29 to 33 IU/l for males, 19 to 25 IU/l for females and levels above this should be assessed. The degree of elevation of ALT and or AST in the clinical setting helps guide the evaluation. -
Total Bilirubin in Athletes, Determination of Reference Range
OriginalTotal bilirubin Paper in athletes DOI: 10.5114/biolsport.2017.63732 Biol. Sport 2017;34:45-48 Total bilirubin in athletes, determination of reference range AUTHORS: Witek K1, Ścisłowska J2, Turowski D1, Lerczak K1, Lewandowska-Pachecka S2, Corresponding author: Pokrywka A3 Konrad Witek Department of Biochemistry, Institute of Sport - National 1 Department of Biochemistry, Institute of Sport - National Research Institute, Warsaw, Poland Research Institute 2 01-982 Warsaw, Poland Faculty of Pharmacy with the Laboratory Medicine Division, Medical University of Warsaw, Poland 3 E-mail: Department of Biochemistry, 2nd Faculty of Medicine, Medical University of Warsaw, Poland [email protected] ABSTRACT: The purpose of this study was to determine a typical reference range for the population of athletes. Results of blood tests of 339 athletes (82 women and 257 men, aged 18-37 years) were retrospectively analysed. The subjects were representatives of different sports disciplines. The measurements of total bilirubin (BIT), iron (Fe), alkaline phosphatase (ALP), alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGT) were made using a Pentra 400 biochemical analyser (Horiba, France). Red blood cell count (RBC), reticulocyte count and haemoglobin concentration measurements were made using an Advia 120 haematology analyser (Siemens, Germany). In groups of women and men the percentage of elevated results were similar at 18%. Most results of total bilirubin in both sexes were in the range 7-14 μmol ∙ L-1 (49% of women and 42% of men). The highest results of elevated levels of BIT were in the range 21-28 μmol ∙ L-1 (12% of women and 11% of men). There was a significant correlation between serum iron and BIT concentration in female and male athletes whose serum total bilirubin concentration does not exceed the upper limit of the reference range. -

Bilirubin (Urine) Interpretive Summary
Bilirubin (Urine) Interpretive Summary Description: Bilirubinuria is an indicator of conjugated bilirubin in the urine. Excessive bilirubinuria in a dog or any bilirubinuria in a cat is an indication to evaluate serum bilirubin concentrations. Decreased Bilirubin Common Causes Normal Artifact o Exposure to UV light or room air o Delayed analysis o Centrifugation of urine prior to analysis o Ascorbic acid (Vitamin C) Increased Bilirubin Common Causes Normal dogs (especially males with concentrated urine) Liver disease, bile duct obstruction RBC destruction (hemolysis) o Immune-mediated hemolytic anemia o Zinc or onion toxicity o RBC parasites Uncommon Causes Hemoglobinuria Fever Prolonged anorexia False positive reactions due to medications o Phenothiazines (e.g., chlorpromazine) o Etodolac Related Findings Liver disease, biliary obstruction o Increased serum bilirubin, ALT, ALP, GGT, AST o Increased serum bile acids o Decreased albumin, cholesterol, BUN and glucose in severe cases o Abnormalities in liver and/or biliary tract on abdominal ultrasound RBC destruction o Decreased hematocrit, RBC, hemoglobin o Increased reticulocytes, increased MCV and decreased MCHC, polychromasia o Increased serum bilirubin o Spherocytosis (in dogs), autoagglutination o Hemoglobinuria o Positive Coombs or saline agglutination test may or may not be present with IMHA Generated by VetConnect® PLUS: Bilirubin (Urine) Page 1 of 2 Additional Information Physiology Conjugated bilirubin passes freely through the glomerular filtration barrier and is excreted in urine. Unconjugated bilirubin is bound to albumin and does not normally pass through the glomerular filtration barrier. Therefore, it is not detectable in urine (unless albuminuria or glomerular disease is present). Bilirubinuria usually precedes hyperbilirubinemia and icterus Dogs: Clinically normal dogs (especially males) may have detectable bilirubinuria in concentrated urine due to a low renal threshold for bilirubin. -

Ideal Conditions for Urine Sample Handling, and Potential in Vitro Artifacts Associated with Urine Storage
Urinalysis Made Easy: The Complete Urinalysis with Images from a Fully Automated Analyzer A. Rick Alleman, DVM, PhD, DABVP, DACVP Lighthouse Veterinary Consultants, LLC Gainesville, FL Ideal conditions for urine sample handling, and potential in vitro artifacts associated with urine storage 1) Potential artifacts associated with refrigeration: a) In vitro crystal formation (especially, calcium oxalate dihydrate) that increases with the duration of storage i) When clinically significant crystalluria is suspected, it is best to confirm the finding with a freshly collected urine sample that has not been refrigerated and which is analyzed within 60 minutes of collection b) A cold urine sample may inhibit enzymatic reactions in the dipstick (e.g. glucose), leading to falsely decreased results. c) The specific gravity of cold urine may be falsely increased, because cold urine is denser than room temperature urine. 2) Potential artifacts associated with prolonged storage at room temperature, and their effects: a) Bacterial overgrowth can cause: i) Increased urine turbidity ii) Altered pH (1) Increased pH, if urease-producing bacteria are present (2) Decreased pH, if bacteria use glucose to form acidic metabolites iii) Decreased concentration of chemicals that may be metabolized by bacteria (e.g. glucose, ketones) iv) Increased number of bacteria in urine sediment v) Altered urine culture results b) Increased urine pH, which may occur due to loss of carbon dioxide or bacterial overgrowth, can cause: i) False positive dipstick protein reaction ii) Degeneration of cells and casts iii) Alter the type and amount of crystals present 3) Other potential artifacts: a) Evaporative loss of volatile substances (e.g. -

Chew, DVM Stephen P. DiBartola, DVM Clinical Handbook Series Preface Urine is that golden body fluid that has the potential to reveal the answers to many of the body’s mysteries. As Thomas McCrae (1870-1935) said, “More is missed by not looking than not knowing.” And so, the authors would like to dedicate this handbook to three pioneers of veterinary nephrology and urology who emphasized the importance of “looking,” that is, the importance of conducting routine urinalysis in the diagnosis and treatment of diseases of dogs and cats. To Dr. Carl A. Osborne , for his tireless campaign to convince veterinarians of the importance of routine urinalysis; to Dr. Richard C. Scott , for his emphasis on evaluation of fresh urine sediments; and to Dr. Gerald V. Ling for his advancement of the technique of cystocentesis. Published by The Gloyd Group, Inc.

Biochemical Profiling of Renal Diseases
INTRODUCTION TO LABORATORY PROFILING Alan H. Rebar, DVM, Ph.D., Diplomate ACVP Purdue University, Discovery Park 610 Purdue Mall, West Lafayette, IN 47907-2040 Biochemical profiling may be defined as the use of multiple blood chemistry determinations to assess the health status of various organ systems simultaneously. Biochemical profiling rapidly has become a major diagnostic aid for the practicing veterinarian for several reasons. First, a more educated clientele has come to expect increased diagnostic sophistication. Secondly, the advent of high-volume clinical pathology laboratories has resulted in low prices that make profiling in veterinary practice feasible and convenient. In addition, improved technology has resulted in the development of procedures that can be used to obtain accurate analyses on microsamples of serum. Such procedures offer obvious advantages to veterinarians, who in the past were hindered by requirements for large sample size. Although biochemical profiling offers exciting potential, it is not a panacea. Since standard chemical screens provide 12 to 30 test results, interpretation of data may be extremely complex. Interpretation is often clouded by the fact that perfectly normal animals may have, indeed, are expected to have, an occasional abnormal test result. It is estimated that in a panel of 12 chemistry tests, approximately 46% of all normal subjects will have at least one abnormal test result. Such abnormalities do not reflect inaccuracies in laboratory test procedures but rather the way in which reference (or normal) values are determined. In order to establish the "normal range" for a given test, the procedure is performed on samples from a large population of clinically normal individuals. -
