    Posted this earlier on in the thread, hope it helps!
    During pregnancy the placenta produces the hormone human chorionic gonadotrophin (hCG). Some of it is lost to the urine and only pregnant women produce hCG, so a urine sample is used to test for pregnancy as hCG will only be present if the woman is pregnant. When a woman takes a pregnancy test, urine passes into the reaction zone of the test stick and some of the monoclonal antibodies there bind to hCG, others do not. These monoclonal antibodies recognise one specific feature of hCG and will only bind to that one; they have blue beads attached to them. All of the monoclonal antibodies pass down to the testing zone which contains polyclonal antibodies which are immobilised. These polyclonal antibodies can bind to numerous parts of hCG so are able to bind despite the fact that the monoclonal ones are attached. Since the polyclonal antibodies are immobilised on the strip, the hCG and thus the blue beads are fixed in this zone, causing it to turn blue. The monoclonal antibodies that didn't bind to hCG move along the strip to the control zone which also contains immobilised antibodies. The monoclonal antibodies bind to the control antibodies, which turns this zone blue as well since all the monoclonal antibodies have blue beads attached. Two blue lines indicates pregnancy.

    The HCG acts as an antigen and binds to monoclonal antibiodies with a blue bead on them however the blue line is only activated once they join to the immobilised antibiodies, the whole antibody complex then moves the the immobilised antibodies and binds again therefore showing a blue line and then the control line forms when the monoclonal antibodies without HCG binded to them bind to the control antibodies

    I dont get those explanations.. But i just read the revision guide and understood it like this:
    There are monclonal antibodies which are attatched to a blue bead or marker and if hcg present then it will bind as its complementary. Complex moves up strip woth urine, and then immobilised antibodies bind to hcg (as complementary) so more concentraded with blue bead/ forming the line ... Is that correct???
