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) a complement fixation test
C) an immunochromatographic assay
D) an ELISA
E) a neutralization assay

Question

Quizplus · Accepted Answer

The pregnancy test kit that the woman is using represents an immunochromatographic assay, where antibodies reacting with a hormone produce two lines on the test strip. Direct immunofluorescence tests, complement fixation tests, ELISAs, and neutralization assays all use different methods for detecting specific antigens or antibodies, and do not produce two lines as a result of antibody-hormone interaction in the way that an immunochromatographic assay does.
