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.
