An objective is to provide a method and an apparatus for accurately extracting a region of an object particle from a urine particle image obtained by taking an image of urine particles in a urine specimen having varying properties. First, a first object region is extracted using one or more of an R image, a G image, and a B image of a urine particle image taken by an image input optical system configured to input particle images. Then, a density distribution and a size of the first object region of one or more of the R image, the G image, and the B image are calculated. Based on these feature parameters, the first object region is classified into a predetermined number of groups. A second object region is extracted from a local region including the first object region, by using one or more of the R image, the G image, and the B image, depending on each of the groups. This configuration allows stable region segmentation for each particle image even for a urine specimen in which urine particles having different sizes and tones coexist.

A urine sample is taken by providing to the person a container having a removable cap with an initially unbroken elastomeric septum puncturable by a blunt tipped pipette and self-resealing following withdrawal of the pipette from the septum. The urine specimen is deposited in the container and the cap replaced. The container with the specimen is conveyed to a laboratory location for analysis where the septum is punctured by manually pressing the blunt tip of a plastic pipette against the septum with sufficient force to puncture through the septum and into the container with the tip. A sample of the urine specimen is drawn into the pipette and the pipette tip withdrawn to allow the septum to self-reseal, such that the urine specimen is sampled for analysis without reopening the container cap following replacement of the cap at the specimen collection site.
