  • Patent number: 5656502
    Abstract: A test strip holder includes an elongated hollow member having an open end and a closed end. A support is provided that positions a test strip within the elongated hollow member spaced from inner walls of the elongated hollow member. At least one vent is positioned between the open end and the closed end of the elongated hollow member. The distance from the open end to the at least one vent opening defines the maximum height of liquid able to enter the elongated hollow member from the open end other than by capillary action. The elongated member may be formed as a tubular conduit. Alternatively, the elongated member may include a test strip receiving part and a test strip covering part, wherein the test strip receiving part may or may not be hingedly connected to the test strip covering part.
