Suppose you are performing an Ouchterlony double diffusion assay loading Ag1 and Ag3 in 2 wells close to the edge and Ab1 and Ab3 in the middle well. Suppose antigen 3 has an epitope in common with antigen 1. One of the antibodies reacts with the epitope common to both antigens. The other antibody reacts with a different epitope on antigen 1 (that is absent on antigen 3). Two precipitin lines form, with a spur pointing toward antigen 3. What does this result indicate?

Identify the phase of the total testing process in which each error occurs.

A new assay is used to test 120 samples from patients with a clinically confirmed diagnosis of the relevant infection and 50 samples from healthy control subjects. The test results were positive for 90 of the infected patients and positive for 10 of the healthy controls. Calculate the positive predictive value of the assay.  

If the concentration of free antibody (Ab) = 3 mol/L, the concentration of free antigen (Ag) = 2 mol/L, and the concentration of antigen-antibody complex = 6 mol/L, then the equilibrium constant K equals:
