Which of the following statements about immunoradiometric assay (IRMA) testing for measuring plasma hormone levels is most accurate?
A) This bioassay test uses an intact animal or a portion of tissue from an animal to calculate specificity and sensitivity.
B) This testing procedure uses antibody-coated plates to produce colored reaction.
C) A 24-hour urine test will be required along with blood tests to calculate specific results.
D) These tests are very specific since they utilize two antibodies instead of one.
Ans: D
Feedback:
Immunoradiometric assay (IRMA) testing is very specific since they utilize two antibodies instead of one. These two antibodies are directed against two different parts of the molecule, and therefore IRMA assays are more specific. Hormones circulating in the plasma were first detected by bioassay test, which used an intact animal or a portion of tissue from an animal to calculate specificity and sensitivity. ELISA testing procedure utilizes antibody-coated plates to produce colored reaction. The IRMA is a blood test, not a urine test.
