Limiting dilution assays are widely used in infectious disease research. These
assays are crucial for current human immunodeficiency virus (HIV)-1 cure research
in particular. In this study, we offer new tools to help investigators design and
analyze dilution assays based on their specific research needs. Limiting dilution
assays are commonly used to measure the extent of infection, and in the context
of HIV they represent an essential tool for studying latency and potential
curative strategies. Yet standard assay designs may not discern whether an
intervention reduces an already miniscule latent infection. This review addresses
challenges arising in this setting and in the general use of dilution assays. We
illustrate the major statistical method for estimating frequency of infectious
units from assay results, and we offer an online tool for computing this
estimate. We recommend a procedure for customizing assay design to achieve
desired sensitivity and precision goals, subject to experimental constraints. We
consider experiments in which no viral outgrowth is observed and explain how
using alternatives to viral outgrowth may make measurement of HIV latency more
efficient. Finally, we discuss how biological complications, such as
probabilistic growth of small infections, alter interpretations of experimental
results.
