When testing blood samples for the presence of disease, considerable efficiencies may be achieved by pooling samples and testing them as a batch. It is shown that placing the samples in a square array and pooling rows and columns has substantial advantages, particularly in the reduction of false negatives. The commonly used 8 × 12 array is also considered.
