Handling method of body fluid sample and analysis apparatus using the same

Abstract

Sample sampling to an analysis apparatus 200 or 820 for analyzing a biochemical analysis item is performed by a pipetting device 202 or 840 which uses a repetitively used pipette nozzle, and sample sampling to an analysis apparatus 100 or 810 for analyzing an immune analysis item is performed by a pipetting device 102 or 830 which uses a disposable nozzle tip. A sample bottle containing a sample to be analyzed on both of a biochemical analysis item and an immune analysis item is sample-pipetted by the nozzle tip first, and then transported so as to be sample-pipetted by the pipette nozzle.

       22 . A method of analyzing body fluid samples which are respectively pipetted from plural sample bottles by using a first pipette and a second pipette disposed on different positions on a line; said method comprising the steps of 
 transferring said plural sample bottles respectively containing said body fluid sample to said line,    after pipetting said body fluid samples using said first pipette, pipetting said body fluid samples using said second pipette, and    analyzing said body fluid samples pipetted using said first pipette and said second pipette by employing a plurality of analysis devices, wherein    an avoiding level of carry-over of said analysis devices of said body fluid samples pipetted using said first pipette is equal to or higher than an avoiding level of carry-over of said analysis devices of said body fluid samples pipetted using said second pipette.    
   
   
       23 . A method of analyzing body fluid samples which are respectively pipetted from plural sample bottles by using a first pipette and a second pipette disposed on different positions on a line; said method comprising the steps of 
 transferring said plural sample bottles respectively containing said body fluid samples to said line,    after pipetting one of said body fluid samples using said first pipette, pipetting other of said body fluid samples using said second pipette, and    analyzing said body fluid samples pipetted using said first pipette and said second pipette by employing a plurality of analysis devices, wherein    an avoiding level of carry-over of said analysis devices of one of said body fluid samples pipetted using said first pipette is equal to or higher than an avoiding level of carry-over of said analysis devices of other of said body fluid samples pipetted using said second pipette.    
   
   
       24 . A method of analyzing body fluid samples which are respectively pipetted from plural sample bottles by using a first pipette and a second pipette disposed on different positions on a line; said method comprising the steps of 
 transferring said plural sample bottles respectively containing said body fluid samples to said line,    after pipetting one of said body fluid samples using said first pipette, pipetting said one of said body fluid samples using said second pipette, and    analyzing said body fluid samples pipetted using said first pipette and said second pipette by employing a plurality of analysis devices, wherein    an avoiding level of carry-over of said analysis devices of said one of said body fluid samples pipetted using said first pipette is equal to or higher than an avoiding level of carry-over of said analysis devices of said one of said body fluid samples pipetted using said second pipette.    
   
   
       25 . A method of analyzing a body fluid sample according to  claim 22 , wherein 
 an analysis device having the higher avoiding level of carry-over is a device for measurement of a label substance after an immune reaction of a substance in the sample to be measured with the label substance, and    another analysis device having the higher avoiding level of carry-over is a device for measurement of an optical characteristic of a reaction solution produced by a chemical reaction of the sample with a reagent.    
   
   
       26 . A method of analyzing a body fluid sample according to  claim 22 , wherein 
 an analysis item having the higher avoiding level of carry-over is a DNA analysis device, and an analysis item having the lower avoiding level of carry-over is a chemical analysis device.    
   
   
       27 . A method of analyzing a body fluid sample according to  claim 22 , wherein 
 a sampled body liquid sample sampled by a pipette used for an analysis device having a higher avoiding level of carry-over is analyzed by the analysis device, and    if the result of judgment is that re-measurement for the analysis on the analysis device is not necessary, sample sampling is conducted by a pipette used for an analysis device having a lower avoiding level of carry-over.
