In the field of medical diagnosis, determination of analytes such as hormones, proteins,
antibodies or antigens is very important to the diagnostic of medical status. Enzyme
immunoassay (EIA) and radioimmunoassay (RIA) are among the most common method
for quantifying such substances However, these methods are usually time consuming
and technically demanding, especial for small sample number. In this invention, an
inexpensive method of semi-quantifying the analyte in biological samples is invented.
This invention can also determine more than one analytes with a single test kit. The
device is using the principle of the one-step colloidal gold immunoassay for
semi-quantifying purpose. By comparing the color intensity of the built-in semi-quantitative
control with the test result, an estimated concentration of the analyte can be obtained.
Also, between each band, a visible marker line will be used to distinguish among bands.
This diagnostic kit with internal semi-quantitative capability may be used for fertility
tests, infectious diseases tests and other one step diagnostic tests.
