Examen de sangre del cordón umbilical - Results

Valores normales:

Los valores normales significan que todos los elementos evaluados están dentro del rango normal.

Significado de los resultados anormales:

Un pH bajo (menor de 7.04 a 7.10) significa que hay niveles más altos de ácidos en la sangre del bebé, lo cual podría ocurrir cuando éste no recibe suficiente oxígeno durante el parto. Una razón para esto podría ser que el cordón umbilical estuvo comprimido durante el trabajo de parto o el alumbramiento.

Un hemocultivo que resulte positivo para bacterias indica la presencia de septicemia.

Se pueden encontrar niveles altos de azúcar (glucosa) en la sangre del cordón si la madre padece diabetes. Después del parto, se vigila al recién nacido en busca de hipoglucemia (bajo azúcar en la sangre).

Los niveles altos de bilirrubina podrían deberse a infecciones que el bebé adquiere antes de nacer, incluyendo:

Otras posibles causas abarcan:

Síndrome de Dubin-Johnson
Ictericia en la madre
Madre que toma sulfamidas durante el embarazo
Incompatibilidad Rh

Nota: 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.
