Abstract

A fluid specimen testing device having a removable lid which carries at least one testing strip behind a transparent top viewing window. Testing is initiated by tilting the device into a stable sideways orientation to allow the specimen to contact the sampling pad portion of the strip. The device is adapted to provide stability in the upright, tilted and inverted orientations. A roll-inhibiting feature also acts as an indicator for proper roll positioning in the tilted configuration. The strips are also oriented in the lid so that they are substantially vertical when the device is in the tilted position thereby enhancing a condition for proper capillarity. The strip is carried close to the upper surface which allows it to be copied on a flat glass copier providing for more objective recordation of the test results.

Claims (19)

1. A method for conducting a test of a liquid specimen, the method comprising:

introducing the liquid specimen into a test device, the test device comprising an opening for receiving the liquid specimen and a lid for sealing the opening, the lid comprising:

at least one test strip carried on the lid;

an aperture exposing a portion of the at least one strip;

an arcuate peripheral flange; and,

roll-inhibiting ears extending from the flange;

sealing the opening with the lid; and

placing the test device in a stable tilted orientation roll-inhibitingly supported by the ears, thereby allowing an amount of said specimen to contact the at least one test strip through the aperture.

2. The method of claim 1 , further comprising maintaining the at least one test strip in a substantially vertical orientation while the specimen test is conducted.

3. The method of claim 1 , further comprising maintaining the test device in the stable tilted orientation using a roll-inhibiting indentation.

4. The method of claim 1 , further comprising maintaining the test device in the stable tilted orientation using roll-inhibiting ears.

5. The method of claim 1 , further comprising viewing the at least one test strip while the test device is in the stable tilted orientation.

6. The method of claim 1 , the lid further comprising a transparent viewing window for viewing the at least one test strip.

7. The method of claim 6 , wherein the at least one test strip is located adjacent to the transparent viewing window.

8. The method of claim 7 , wherein the at least one test strip is located within at least one channel, the at least one channel being located on an interior surface of the lid.

9. The method of claim 8 , wherein the at least one channel further comprises the aperture.

10. The method of claim 9 , wherein the portion of the at least one test strip extends through the aperture.

11. The method of claim 10 , further comprising allowing an amount of said specimen to contact the at least one test strip through the aperture.

12. The method of claim 1 , wherein the at least one test strip is visible while the test device is in the stable tilted orientation.
