[Also in Divisions Bl, B8 and G1] A blood donation receptacle 21 and a sample cup 34 are connected by a strip 33 which bears in several places a donor identity number 42 and a code 43 representing the same number in a form such as punched holes, varying opacity or localy magnetised parts of an oxide film. Receptacle 21 and cup 34 are filled at the same donation and strip 33 is severed at line 44. Sample cups are loaded on a sample plate (52) (Fig. 4, not shown) with strips 33 projecting (Fig. 3, not shown), and plate (52) is indexed to bring successive cups under sample take off crook (62), whereby samples are drawn into automatic analyser (63) and analysed using anti-serum to determine groups. The result of each sample analysis is recorded on a moving chart (76) in terms of four traces produced by pens (69), (71), (72), (73). The descent of crook (62) actuates a mercury switch (91) which actuates a solenoid moving detector (81) to 'read' the code 43 on the adjacent strip 33, the code 43 being thus printed as a number (84) on chart (76). The analysis time is equal to the time taken for a cup 34 to move from crook (62) round to detector (81) so that the number (84) is printed adjacent the traces representing the corresponding sample on chart (76). Thus the receptacle 21 and a chart portion bearing the corresponding analysis bear the same identity number.
