An apparatus for processing and analyzing blood serum includes an input rack for holding test tubes containing whole blood specimens and separator gel, a centrifuge, an optical sensing unit for receiving centrifuged test tubes and generating output signals indicative of whether the centrifuging was successful and, if it was, the boundary position between the separator gel and the blood serum, and a computer connected to receive and analyze the output signals of the optical sensing unit. An aspirator/dispenser needle unit is positioned above the sensing unit and is capable of lowering a needle, under the control of the computer, to puncture the stopper of a test tube and then withdraw blood serum. The apparatus also includes a cup feeder station for storing and dispensing empty cups for receiving and holding blood serum dispensed from the needle, an noutput rack for holding cups containing blood serum samples along with the corresponding test tubes, a bar code reader for identifying test tubes, and a disposal station for receiving test tubes determined to be defective by the computer. A robotic arm moves the tube from station to station under the control of the computer.
