FIG. 2.

Cost-saving ability of pooling processed urine specimens before the performance of the LCR test for the detection of genital C. trachomatis infections. The graph shows the cost per sample when the pooling algorithm was used, depending on the number of specimens pooled and taking into account various prevalences of infection in the population screened. A baseline total cost of $12.76 per individual sample which included laboratory consumables, technician time, and LCR unit dose costs was used.
