Regression analysis for multiple‐disease group testing data

Abstract: Group testing, where individual specimens are composited into groups to test for the presence of a disease (or other binary characteristic), is a procedure commonly used to reduce the costs of screening a large number of individuals. Group testing data are unique in that only group responses may be available, but inferences are needed at the individual level. A further methodological challenge arises when individuals are tested in groups for multiple diseases simultaneously, because unobserved individual disea… Show more

“…In the group testing scenario, pooling can effectively reduce cost while adequately determining which patients have a particular disease . Similar to the original motivation for pooling popularized by Dorfman , the goal of these methods is often to reduce the total lab cost by minimizing the number of lab tests required to identify infected patients.…”

“…Regression analysis for this type of data remains mostly untapped. To the best of our knowledge, the only work is an approach based on generalized estimating equations . However, it did not consider retesting outcomes arising from the second stage of screening and thus does not apply to the SHL screening practice.…”
