Method and apparatus for determining the erythrocyte sedimentation rate.

摘要

IN A METHOD FOR IMPROVED measure the speed of erythrocyte sedimentation (ESR) USING A TEST TUBE PRE-CASTING (T) to collect a blood specimen. TUBE (T) is made of a material such as glass or plastic and contains an anticoagulant AGENT / MIXER. FOR TEST TUBE (T) is placed in a frame (1) and loaded INSIDE AN INSTRUMENT MIXING BRIEFLY specimen. USING AN OPTICAL SENSOR (3) to record the location of the menisci BLOOD / AIR baseline. INTERVAL TIME SUBSEQUENT IN PERIODS OF UP TO 20 MINUTES OR LESS, THE SENSOR OPTICAL (3) identifies and measures the location of the inter-cell / PLASMA (I) within an observation window constituting part LESS THAN THE TOTAL LENGTH TUBE (T). MEASURED VALUE is converted by an algorithm (10, 11) THAT MAY BE OBTAINED VALUE using the method WESTERGREN classic.
