Question

A woman uses a home pregnancy test kit that tests for hCG hormone in urine. She knows this is a type of antibody assay from the kit brochure. Antibodies reacting with the hormone produce two lines on the test strip. What specific type of antibody assay does this represent?

A) a direct immunofluoresence test
B) an immunochromatographic assay
C) a complement fixation test
D) an ELISA
E) a neutralization assay

Answer 1

B) an immunochromatographic assay

Step-by-step explanation:

An immunochromatographic assay is a rapid chromatographic immunoassay for the qualitative detection of human chorionic gonadotropin hormone in urine or serum to aid in the early detection of pregnancy.

These pregnancy tests are specifically desgined for professional users for determination of early pregnancy,but have also found a place in home pregnancy testing applications due to ease of use and low cost. The specificity is 98% meaning that test is highly selective for hCG glycoprotien.

Hence B) an immunochromatographic assay is the right answer.

Answer 2

B) an immunochromatographic assay

Step-by-step explanation:

Based on the scenario being described it can be said that the antibody assay being represented is known as an Immunochromatographic assay. This is also known as lateral flow dipstick immunoassay or strip test, these strips help test for certain things such as pregnancy. They were developed in 1956 by Singer and Plotz.
