Prepare a copper sulfate solution with a stepwise change in o and oot between 35 and 1.075, drop blood collected from about 1 cm above the liquid level one by one, and use sulfuric acid solution in which the dropped blood neither settles nor floats. The specific gravity of the copper solution was taken as the specific gravity of blood.

Lead to mirror (4). One of the lights separated by the dichroic mirror (4) is passed through a green filter (5) whose peak wavelength of transmission is around 545 nm.
(Fuji Filter BPB-55) and the concentration is detected by a photodiode (7). The other spectrally separated light passes through a red filter (Meris Guno 03FII002) with a peak transmission wavelength of around 760 nm, and its concentration is detected by a photodiode (8). When the difference in concentration between the two is determined by the method of the present invention, a good correspondence with the specific gravity of blood can be obtained. Therefore, the method of the present invention allows the specific gravity of blood to be determined.
