Abstract:
Devices and methods for collecting a fluid specimen and testing it are disclosed that avoid unduly exposing the tester to the specimen and eliminate the possibility of contaminating the remaining portion of the collected fluid. The device includes a first compartment for collecting the fluid and provides controlled volumes of fluid from the first compartment to a second compartment where the fluid is accessible to test strips. Fluid from the first compartment is transferred to the second compartment by use of a fluid metering valve having a valve cylinder with one or more wells formed on the surface of the cylinder. The fluid metering valve is fluidly connected to the first compartment at a first valve position and is fluidly connected to the second compartment at a second valve position.
