Sensitivity
Detection Levels for Human hCG Hormone
One-Step Pregnancy Tests
• Brand Comparison Chart
For
many women, early detection of pregnancy is desired. Clearly, the more sensitive
a pregnancy test is to detecting hCG levels post fertilization, the earlier a
preliminary diagnosis of pregnancy can be obtained. Virtually all one-step
"at home" pregnancy tests employ the same technology in test
construction and scientific principle; a lateral flow immunoassay in which
hormone specific antibodies bind with a pretreated colloidal gold precipitate
impregnated within the test panel to form a visible line on the test panel of
the device.
All
pregnancy test kits are not, however, produced with the same sensitivity level
at which hCG hormone can be detected. The reasons for this are primarily
production cost related having to do, in part, with the amount of colloidal gold
incorporated into the test. Below is a table listing many brands of professional
and over-the-counter (OTC) pregnancy test kits and the sensitivity hCG detection
level indicated either in package instructions or registration documents.
