Examen de NAT
Normalmente, los glóbulos blancos se tornan azules cuando se agrega el nitroazul de tetrazolio, lo cual significa que las células deben ser capaces de destruir bacterias y proteger a la persona de infecciones.
Los rangos de los valores normales pueden variar ligeramente entre diferentes laboratorios. Hable con el médico acerca del significado de los resultados específicos de su examen.
Si la muestra no cambia de color cuando se agrega el nitroazul de tetrazolio, los glóbulos blancos carecen de la sustancia necesaria para destruir bacterias. Esto puede deberse a la enfermedad granulomatosa crónica.
