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.
Una punción arterial se lleva a cabo para obtener muestras de sangre de las arterias. Estas muestras se toman principalmente para realizar una gasometría arterial (que puede indicar problemas respiratorios o trastornos metabólicos). Sin embargo, las punciones arteriales se realizan algunas veces con el fin de obtener muestras para un hemocultivo o un análisis bioquímico de la sangre.
