What happens, using Information about Monoclonal Antibodies, in a Pregnancy Test if you are Positive?

Author: go kys



Answer:

-If you are Pregnant, then your Urine will have a Hormone [HCG] -The Bit where you Wee on will have Antibodies to HCG, that itself has Blue Beads Attached. -As you Pee, HCG will Bind onto the Antibodies, and Move because of the Liquid [Your Piss] -It then will reach the Strip, where there is More Antibodies for the Hormone, with the Difference being they are Stationary. -So HCG will Bind on to that Still Antibody, and will get Stuck - and the Blue Beads that is now also Stuck will begin to make a Blue Line on the Test Strip - Saying you are Pregnant!!
