IV indicates intravenously; -, not required; Neg, negative; ND, not done; Aggl, agglutination; Pos, positive; and IM, intramuscularly.

Blood was tested with a panel of 11 test RBC types. Some of them showed a very weak agglutination, but a specific antibody could not be identified. Agglutination was scored by visual assessment from ++++ (strong agglutination) descending to - (no agglutination) as defined by the DiaMed ID gel scale. The positive agglutination was rated as a 1+ reaction on the ID gel scale
