• Question 241:

  Post-hepatic obstruction is characterized by a marked increase in alkaline phosphatase, GGT, conjugated bilirubin, as well as other hepatic enzymes. The slight rise of ALT suggests that the issue is not hepatitis. Renal and cardiovascular

  failure do not match the symptom of jaundice or the abnormal laboratory values.

  Chem

  A. medical technologist
  B. medical laboratory scientist

• Question 245:

  The term affinity refers to the strength of attraction between a single antigenic determinant and a corresponding antigen binding site. The term avidity refers to the total strength of the attraction between an antibody and a multivalent antigen. The reaction between an IgM molecule (which has 10 antigen binding sites), and a multivalent antigen is therefore much stronger than that of an IgG antibody (which has only 2 antigen binding sites).

  Avidity is best described by which of the following statements:

  A. The strength with which red cells agglutinate
  B. The strength with which multivalent antigens and antibodies bind
  C. The strength with which univalent antigens and antibodies bind
  D. The speed with which an antigen-antibody reaction occurs
  B. The strength with which multivalent antigens and antibodies bind

• Question 246:

  Western blot analysis is frequently utilized as the confirmatory method of HIV detection.

  Which of the following assays is routinely used for confirmation of HIV infections:

  B. Western blot
  C. In-situ hybridization
  D. Radioimmunoassay
  B. Western blot

• Question 249:

  Troponin is a very specific biomarker that is released during cardiac injury or stress. CK is found not only in cardiac tissue, but also in muscle and brain tissue. LD levels can be elevated in cardiac events, tissue breakdown, and hemolysis.

  Myoglobin is elevated when muscle tissue is damaged and is not specific for the heart muscle.

  A. CK
  B. LD
  C. Troponin
  D. myoglobin
  C. Troponin

  The selectivity of an ion-selective electrode is determined by the:

  A. properties of the membrane used
  B. solution used to fill the electrode
  C. magnitude of the potential across the membrane internal reference electrode
