(1) TR is used to assay salicylate and not aspirin (acetylsalicylic acid). Choose ONE response that correctly states why this is important:
- Salicylate is the main active metabolite of aspirin, so establishing its presence in patient samples is more significant from a clinical perspective;
- Salicylate is only detectable in samples taken from patients with severe inflammatory conditions;
- Salicylate is the only drug available for treating irritation of the stomach mucosa (gastritis), so it’s crucial that it can be detected in stomach contents.
- In this case, the patient obviously possesses a genetic trait which means they will convert all of an aspirin dose to salicylate rapidly.
Required
(2) When the patient serum sample was mixed with TR, a precipitate was formed.
Choose the explanation that best explains this observation:
- TR provides a strongly alkaline environment, causing all macromolecules
- (including proteins) to form a precipitate;
- TR forms of a precipitate with proteins, due to the presence of Cu 2+ and Fe2+
- ions. This reaction is only able to occur in a neutral pH environment;
- TR provides a strongly acidic environment, thereby causing the precipitation of
- proteins;
- The pH of TR has no bearing upon the formation of precipitate, and this was due
- to the presence of another chemical component of the reagent.
