Abstract: A system for collection and delivery of sub-milliliter liquid samples is described that provides a dramatic simplification for the measurement of clinical values. The system produces high dilutions of capillary size samples, such as bodily fluids or blood, by a factor of 1000 or more. Multiple assays can be conducted on a sample of 0.1 cc or less. A small lancet can create a drop of blood on a fingertip or other location, which can be collected into a self-priming capillary blood collector. The sample is then loaded into a consumable loader. Then a fluid, such as saline, is flowed into the consumable loader, and passes through the capillary collector, washing out the fluid. Downstream, the blood in the capillary is reliably diluted by mixing with appropriate reagents to allow analysis of selected blood properties. One or more individual bubbles can be inserted into the stream during loading. The capillary loading system can be used for one or several assays on a single blood sample.
