Ppt Understanding Diagnostic Tests Powerpoint Presentation Free Understanding diagnostic tests p.j. devereaux, md, phd mcmaster university. goals • understand sensitivity and specificity • inform why they are in general problematic • discuss likelihood ratios • inform pretest and posttest probabilities of disease • understand testing and treatment thresholds • go through case examples • convince you that understanding diagnostic properties is. Identify and convert the pre test probability to pre test odds. 2. determine the post test odds using the formula, post test odds = pre test odds * likelihood ratio 3. convert the post test odds into post test probability. likelihood ratio: example • a 52 yr woman presents after detecting 1.5 cm breast lump on self exam.

Liver function tests (lft) the document discusses the anatomy, functions, and tests related to evaluating the liver. it notes that the liver is the largest organ located in the upper right abdomen and contains hepatocytes as its main cells. the liver has important metabolic, excretory, hematological, storage, protective, and detoxification. A battery of tests are needed since the liver has diverse functions including excretion, metabolism, protein and plasma synthesis, and storage. specific tests mentioned include liver enzymes, albumin, prothrombin time, tumor markers, bilirubin, and dye excretion tests. the types of jaundice hemolytic, obstructive, and hepatic are. Slide 2 . objectives upon completion of this lecture, the students should be able to: understand the major metabolic functions of the liver and causes of liver dysfunction. discuss markers of liver function tests such as liver enzymes, bilirubin, albumin and prothrombin time that can diagnose hepatic injury and assess hepatic function. slide 3 .

Compares patient to normal control. test the livers synthetic function. 13. are these liver function tests. alt, bilirubin and alp tell us nothing about the. function of the liver. these are markers of liver dysfunction or damage. albumin and prothrombin time may give an. indication of the livers synthetic ability.
