摘要:
Hemoglobin in a sample solution is quickly and reliably denatured; at the same time, quick and accurate measurement of hemoglobin and a hemoglobin derivative is realized. In a method for measuring hemoglobin and a hemoglobin derivative, and a reagent composition, a measurement kit, an analysis device, and an analysis system used in the method, a sample solution containing a blood component is treated with a nonionic surfactant, an oxidizing agent, and a metal salt to denature hemoglobin in the sample solution to measure the hemoglobin, and thereafter the amount of a hemoglobin derivative in the sample is measured by an immunological method using an antibody specifically binding to a denatured site of the denatured hemoglobin derivative.

An analysis device comprises a separation chamber for separating a sample solution into a solution component and a solid component, a holding channel, a mixing chamber connected to the holding channel, an overflow channel connected between the holding channel and the separation chamber, a sample overflow chamber into which the sample solution remaining in the separation chamber is discharged, and a joint channel connecting the separation chamber and the sample overflow chamber. After the separated solution component fills the overflow channel with priority, the separated solid component is transferred to the holding channel via the overflow channel, and a predetermined amount of the solid component is measured. The solid component in the holding channel is transferred to the mixing chamber by a centrifugal force, and simultaneously, the sample solution remaining in the separation chamber is discharged to the sample overflow chamber by the siphon effect of the joint channel.

In an image forming apparatus of a rotary type, when a pause is made during continuous image formation, the time taken to restart image formation after the pause is shortened so as to reduce stress on the user. In the image forming apparatus, it is determined beforehand whether the next image formation mode is a color mode or a mono mode, and a developing device to be first used in the next image formation mode is moved to a developing standby position.

Herein discloses is a testing device, comprising therein an inlet port introducing a blood specimen thereinto, a blood separating chamber held in fluid communication with the inlet port through a fluid passageway to receive a blood specimen, and a hemolyzed blood chamber having accommodated therein a hemolyzed blood fluid. The testing device is operative to be rotated around a rotation center and stop from being rotated to have the blood specimen accommodated in the blood separating chamber into blood cells and a blood plasma fluid, and the blood separating chamber is held in fluid communication with the passageway merging area through a fluid passageway to have the blood plasma fluid separated from the blood specimen flowed through the fluid passageway, in such a manner that the hemolyzed blood fluid is mixed and diluted with the blood plasma fluid in the passageway merging area at a predetermined dilution ratio.
