Abstract:
A patient-specimen identification system provides error-free identification of a specimen or sample from the time it is taken from a patient to the time when the results of the sample analysis are reported. Machine-readable labels are attached to the patient and to each container in which a sample or sub-sample may be contained. The machine-readable labels each contain a permanently encoded unique random number. When a sample is taken from the patient, the labels attached to the patient and the sample container are read and the two numbers are stored in an associated manner. Similarly, when portions of the sample are transferred to sub-sample containers, labels attached to the sample container and the sub-sample container are read and the two numbers are stored in an associated manner. The sub-samples are analyzed and the analysis results are associated with the number on the sub-sample container label. The analysis results are then correlated to the patient''s identity and the analysis results and patient''s identity are printed out in an associated manner.
Abstract:
A METHOD OF SEPARATING PLATELETS FROM WHOLE BLOOD OR BLOOD CONSTITUENT BY SEPARATION FRACTIONATION IS DISCLOSED IN WHICH A COMBINATION OF REAGENTS INCLUDING FORMALDEHYDE OR OTHER SUITABLE BLOOD FIXATIVE AGENT AND A SEPARATION DEXTRAN POLYMER OR OTHER SUITABLE SEPARATION AGENT ARE ADDED TO THE WHOLE BLOOD FOR SEPARATING A PLATELETCONTAINING FRACTION THEREOF AND THE RESULTING MIXTURE ALLOWED TO SEPARATE LEAVING A LAYERED STRUCTURE FROM WHICH THE DESIRED FRACTION MAY BE EASILY RECOVERED.
