Determinación del grupo sanguíneo ABO (hemoclasificación); Pruebas cruzadas; Determinación del Rh

Valores normales:

Tipificación ABO:

Si sus glóbulos sanguíneos se pegan o aglutinan al mezclarse con:

  • Suero anti-A, usted tiene sangre tipo A.
  • Suero anti-B, usted tiene sangre tipo B.
  • Sueros anti-A y anti-B, entonces usted tiene sangre tipo AB.

Si los glóbulos sanguíneos no se pegan o aglutinan cuando se agrega suero anti-A y anti-B, usted tiene sangre tipo O.

Prueba inversa:

  • Si la sangre se aglutina únicamente cuando se agregan células B a la muestra, usted tiene sangre tipo A.
  • Si la sangre se aglutina únicamente cuando se agregan células A a la muestra, usted tiene sangre tipo B.
  • Si la sangre se aglutina cuando se agregan cualquiera de los tipos de células a la muestra, usted tiene sangre tipo O.

La falta de aglutinación de los glóbulos sanguíneos cuando la muestra se mezcla con ambos tipos de sangre indica que usted tiene sangre tipo AB.

Tipificación del Rh:

  • Si los glóbulos sanguíneos se pegan o aglutinan al mezclarlos con suero anti-Rh, usted tiene sangre de tipo Rh positivo.
  • Si la sangre no coagula al mezclarse con suero anti-Rh, usted tiene sangre de tipo Rh negativo.
