Claim Text:
1. A method comprising: using an accelerated blood component separation technique on a blood sample in a non-capillary vessel for a first period of time at a first compaction force to separate formed blood components from plasma, wherein the first period of time occurs during an estimated linear portion of a compaction curve; using image capture of the sample at two different times during the first period of time to determine an uncorrected sedimentation rate based on plasma/formed component interface location at those two different times; using the accelerated blood component separation technique on the blood sample for a second period of time at a second, greater compaction force than the first compaction force; and determining sedimentation rate of the formed blood component based on at least the following: the uncorrected sedimentation rate and a hematocrit correction factor based on the hematocrit of the sample; wherein said determining occurs without determining a mathematical function for a non-linear segment of the sedimentation curve representative of the magnitude of intercellular erythrocyte repulsion in the blood sample.
