Patent ID: 8900514

Claim:
A blood analyzing device comprising: a holder including a stationary holder portion arranged for carrying a container having a cuvette comprising a blood sample, said cuvette having a longitudinal extension in a first dimension and a comparatively shorter extension in a second dimension, and a rotatable portion that rotates the stationary holder from a first position in which the stationary holder carries said container in a loading position such that the longitudinal axis of said cuvette is substantially parallel with a horizontal axis to a second position in which the stationary holder carries said container in a measuring position in which the longitudinal axis of said cuvette is angled with an angle larger than zero but smaller than ninety degrees relative to the horizontal axis; a light source arranged for providing input light of a wavelength at which a hemoglobin, Hb, species has absorbance into said blood sample; a light detector arranged for detecting output light from a measuring volume constituting a sub-portion of said blood sample at multiple time instances; a Hb processor connected to said light detector and configured to determine kinetic information representative of a change in red blood cell concentration over time in said measuring volume based on output light detected by said light detector at said multiple time instances; and an ESR processor connected to said Hb processor and configured to determine an erythrocyte sedimentation rate, ESR, in said blood sample based on said kinetic information received from said Hb processor, wherein, said measuring volume is positioned in connection with a first end of said cuvette in said longitudinal extension, and said measuring volume comprises a first measuring volume positioned in connection with said first end of said cuvette in said longitudinal extension and a second measuring volume positioned in connection with a second opposite end of said cuvette in said longitudinal extension.
