Your patient is instructed to collect his urine for a 24 hour catecholamine test. What catecholamine metabolites will we be measuring: A. 3-Methoxy-4-hyroxymandelic acid (VMA) B. homovanillic acid (HVA) C. both of the above D. none of the above

Step 1
This test is used to measure the levels of catecholamines and their metabolites in the urine over a 24-hour period. Catecholamines include dopamine, norepinephrine, and epinephrine, and their metabolites are substances that are produced when these hormones are Show more…

You have tested the concentration of phenylalanine, tyrosine, and tryptophan in the brain of a patient with PKU. The levels of phenylalanine are abnormally high and the levels of tryptophan and tyrosine are very low. Part 1. What could be the cause of this? Excess phenylalanine stimulates an exporter of tryptophan and tyrosine. Excess phenylalanine alters pH levels which inhibits tryptophan and tyrosine transport across the blood-brain barrier. Excess phenylalanine in the blood competes with tryptophan and tyrosine for the same transporter across the blood-brain barrier. None of the above unanswered Part 2. What could be an outcome for this patient if not adequately treated? Dopamine and serotonin metabolism in the brain could be hindered. Dopamine and serotonin metabolism in the brain could be increased. Production of fats in the brain could be stalled. Production of fats in the brain could be increased. None of the above

10-14: The pathway shown above depicts the synthesis of the catecholamine family of neurotransmitters from tyrosine. 10. Which essential amino acid (not shown above) is an immediate precursor? 11. Tyrosine is converted to dopa by 12. Dopa is converted to Dopamine by 13. Dopamine is converted to Norepinephrine by 14. Norepinephrine is converted to Epinephrine by Pick the best answer or fill in the blank 15. Citrulline is a a) Precursor of arginine b) Metabolite of nitric oxide c) Both d) Neither 16-19. An example of transamination is accepting from to become 20. The native configuration of a protein can be disrupted by a) Heat b) Agitation c) Change of PH d) All 21. Hormones which have an anabolic effect on protein include all except a) Insulin b) Growth hormone c) DHEA d) Cortisol 22. Which of the following vitamins is required for transamination: a) Thiamine b) Riboflavin c) Niacin d) Pyridoxine e) Cyanocobalamin

Which one of the following is not an NPN? Allantoin Ammonia Creatinine Elevated urea concentration is termed: Azotemia BUN Uremia Uremic syndrome Azotemia caused by: Prerenal Acute renal failure Chronic renal failure Congestive heart failure Urinary tract obstruction Which compound constitutes roughly half of the NPN in blood? Ammonia Creatinine Urea Uric acid A technologist obtains a urea value of 40 mg/dL and a serum creatinine value of 2.5 mg/dL on a patient. These results indicate: Congestive heart failure Dehydration Glomerular nephritis Urinary tract obstruction A technologist reports urea of 10 mg/dL. What is the concentration for this sample? 3.2 mg/dL 4.2 mg/dL 18.0 mg/dL 21.4 mg/dL Which blood collection tube additive can be used to collect a specimen for measurement of urea? Ammonium heparin Lithium heparin Sodium citrate Sodium fluoride Uric acid is the final product of: Allantoin metabolism Amino acid metabolism Purine metabolism The urea cycle Sources of error in measurement of uric acid include: Protein interference Competition from alternate purine substrates Narrow spectrophotometer bandwidth Nonspecific enzyme activity In the clinical laboratory, urea is measured most frequently using: Conductivity Enzymatic reactions Isotope dilution mass spectrometry Multilayer film formats
