This test uses an anti-hCG antibody to detect for the presence of hCG. Use your knowledge of immunology and how antibodies work to explain how this reaction takes place.
Homework Answers
hCG is a protein which has many epitopes which acts like antigen for anti-hCG antibody. the anti-hCG antibody is tagged with some chromogen. This chromogen is activated when an anti-hCG antibody binds to hCG. hCG is passed out by urine. When we test the urine sample for the pregnancy, a drop of urine is put on the strip. If the woman is pregnant then there is a change in color other strip remain colorless.

A medical test has been designed to detect the presence of a certain disease. Among people who have the disease, the probability that the disease will be detected by the test is 0.94. However, the probability that the test will erroneously indicate the presence of the disease in those who do not actually have it is 0.05. It is estimated that 6% of the population who take this test have the disease. (Round your answers to three decimal places.) (a)...

A new test is developed for detecting the presence of steroids in athlete urine samples. The test could produce false negative results 5% of the time. It could also produce false positive results 10% of the time. Based on past evidence, it is believed that 2% of the athletes do use steroids. This test is administered to an athlete, and his test result is positive for steroids. What is the probability that this athlete actually used steroids? Show your work....
