Abstract
A sample container containing a urine sample is transferred by a sample positioning device to a liquid level sensing position. At this sensing position, the liquid level in the sample container is detected by a level sensor, followed by transfer of the sample container to a dipping position. A liquid level rising member is then inserted into the sample container. While being held by a handling device, a test strip is dipped into the sample in the sample container with the liquid level raised. Thereafter, the test strip is lifted out of the sample container and transferred to a measuring device. Color development in reagent sections on the test strip is measured by a photometer in terms of the reflected light strength. With the present invention, analysis using test strips can be implemented even when the sample volume into the sample container is small.
