Fig 1. Correlation of the 3 point-of-care assays with values within the dynamic range of the reference Hemoglobin meter in 60 samples in a central laboratory (phase 1), and 100 samples in a community based clinical setting (phase 2).

In phase 1 of the study the STAT-Site had a high failure rate. It seems that this was related to uneven migration of the sample through the sample strip, resulting in the sample migration time exceeding the maximum time specified by the manufacturer.
