A specimen information detection apparatus comprising: an image capture device configured to capture an image of a specimen container that contains a specimen, wherein the specimen container comprises a label including a print portion indicating a barcode and an exposed portion in at least a part of the outer circumferential surface where no label is attached; an illumination device configured to irradiate the specimen container with light sideways with respect to an image capturing direction when the image is captured, wherein the illumination device is configured to irradiate the specimen container with light emitted from both sides in a light irradiation direction intersecting the image capturing direction in which the specimen container aligns with an image detection axis when the image is captured; and an information processing portion configured to detect a chylous state, a hemolysis state, or a foreign-substance containing state in the specimen container through image processing based on image information of the specimen container acquired by capturing the image of the specimen container; and wherein the specimen information detection apparatus further comprises: a chamber configured to house the specimen container and block an external light when the image is captured; a label sensor configured to detect a position of an edge of the label of the specimen container, thereby detecting an orientation of the specimen container; and a position adjustment device configured to adjust the orientation of the label attached to an outer circumferential surface of the specimen container before the image is captured, such that the print portion indicating said barcode faces an opposite side of the image capture device as viewed in the image capturing direction, characterized in that the illumination device is disposed so that a center angle between the light irradiation direction and the image capturing direction at a center position of the specimen container is in a range of 60 degrees to smaller than 90 degrees and in such a positional relationship that the light emitted from the illumination device can enter the specimen container through the exposed portion and reflect at the rear surface of the label, functioning as a reflector, to the image capture device without transmitting through the print portion of the label. an image capture device configured to capture an image of a specimen container that contains a specimen, wherein the specimen container comprises a label including a print portion indicating a barcode and an exposed portion in at least a part of the outer circumferential surface where no label is attached; an illumination device configured to irradiate the specimen container with light sideways with respect to an image capturing direction when the image is captured, wherein the illumination device is configured to irradiate the specimen container with light emitted from both sides in a light irradiation direction intersecting the image capturing direction in which the specimen container aligns with an image detection axis when the image is captured; and an information processing portion configured to detect a chylous state, a hemolysis state, or a foreign-substance containing state in the specimen container through image processing based on image information of the specimen container acquired by capturing the image of the specimen container; and wherein the specimen information detection apparatus further comprises: a chamber configured to house the specimen container and block an external light when the image is captured; a label sensor configured to detect a position of an edge of the label of the specimen container, thereby detecting an orientation of the specimen container; and a position adjustment device configured to adjust the orientation of the label attached to an outer circumferential surface of the specimen container before the image is captured, such that the print portion indicating said barcode faces an opposite side of the image capture device as viewed in the image capturing direction, a chamber configured to house the specimen container and block an external light when the image is captured; a label sensor configured to detect a position of an edge of the label of the specimen container, thereby detecting an orientation of the specimen container; and a position adjustment device configured to adjust the orientation of the label attached to an outer circumferential surface of the specimen container before the image is captured, such that the print portion indicating said barcode faces an opposite side of the image capture device as viewed in the image capturing direction,
