Principles of Body Fluid Analysis and Principles of Hemoglobin Analysis in Clinical Chemistry 1. Select the estimated laboratory values for iron deficiency anemia 1. Low TIBC 2. High transfer... rin saturation 3. High ferritin 4. High transferrin 2. A 27-year-old Male patient presents to his physician with vague abdominal pain and this only occurs occasionally. The physician doesn't think that anything is wrong, so he just orders a bunch of tests to make sure that he doesn't get sued for missing something. The patient is found to have increased conjugated bilirubin. What disease could possibly be correlated with this finding? 1. Dubin-Johnson syndrome 2. Criggler-Najjar syndrome 3. Rotor syndrome 4. Gilbert syndrome 3. Name some common causes of prehepatic jaundice 1. Disseminated Intravascular Coagulopathy 2. Acute Interstitial Nephritis 3. Interstial Pneumonia 4. Necator americanus infection 4. What is the eventual fate of hemoglobin to be excreted? 1. Uric acid 2. Bilirubin 3. Creatinine 4. Porphobilinogen 5. How is amniotic fluid is assessed for hemolytic disease of the fetus and newborn? 1. Creatinine 2. Delta 450 3. MoM 4. Lecithin/Sphingomyelin ratio 6. A CSF sample comes across your workstation and you assess it with a White Blood Count, glucose, and protein assays. What would you expect if the patient has slightly decreased glucose with an increase in WBCs and a lymphocytic predominance? 1. Viral infection 2. Traumatic tap 3. Bacterial meningitis 4. Brain tumor 7. A patient presents with a cough and pleural effusion. Thoracentesis reveals a milky fluid with elevated lipid levels. What is the likely cause of this effusion? 1. Melanoma 2. Lymphatic obstruction 3. Anaerobic empyema 4. Pneumonia 8. What is the best test to diagnose porphyria cutanea tarda? 1. Urine porphyrins 2. Zinc protoporphyrin 3. Serum porphyrins 4. Urine porphobilinogen 9. A 48-year-old male alcoholic patient presents with significant ascites with a specific gravity of 1.008. What would you expect the peritoneal fluid SAAG to be? 1. 5 2. 3.5 3. 0.9 4. 1.3 10. Which tube is collected last in CSF fluid collection? 1. Hematology 2. Chemistry 3. Microbiology 4. Cytology 11. What is the big picture of a patient with a transudative effusion into a body cavity? 1. Tumor proteins attracting water 2. Lipid levels attracting water 3. Chronic infection attracting water 4. Stagnant fluid being pushed into the cavity 12. Select the proper storage and handling requirements for bilirubin 1. Protect from light 2. Hemolysis will increase the diazo reaction 3. Cloudy samples should be assayed prior to centrifugation 4. Stored at RT for 2 days 13. A 43-year-old G5P5 (Been pregnant 5 times, and gave birth 5 times) overweight female is complaining of Right upper abdominal pain which started about a month ago and is worse about an hour after a fatty meal. The physician performs a bedside ultrasound and visualizes a gallbladder full of gallstones. Cholecystitis is the tentative diagnosis, and the laboratory values for what test method would be increased? 1. Evelyn-Malloy 2. Jendrassik-Grof 3. Watson-Schwarz 4. Hoesch 14.
