Answer to Question 1

ANS: D
Immunologic methods measure the actual coagulation protein rather than fibrin formation. These assays are based on antigen-antibody reactions.

Answer to Question 2

ANS: C
The heparin anti-Xa assay is used to indirectly measure the concentration of heparin. In this system, heparin has an inhibitory effect on the enzyme Xa. Xa normally proteolytically cleaves the chromogenic substrate, releasing the chromogen with a color intensity that is then measured. Because heparin has inhibited some of the Xa, less free Xa will be available to cleave the substrate and less color will be released. Thus the concentration of heparin is inversely proportional to the activity of Xa. This is classified as an indirect measurement.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
