ABSTRACT:
A specimen testing method and an apparatus capable of extracting accurate serum components depending on a patient even if the amount of the serum components in blood varies in each specimen. The apparatus comprises a visual sensor for taking an image of blood separated into serum components and clot components, an image memory for storing digital image data output from the visual sensor, a serum component upper boundary position detecting means for detecting an upper boundary position of the serum components from the digital image data stored in the image memory, a serum component lower boundary position detecting means for detecting a lower boundary position of the serum components, and a serum component amount measuring means for measuring the amount of the serum components from the upper boundary position and lower boundary position.
