What is Cord PH and what can Cord Blood Gas tests tell you about your baby at birth

Cord Blood Gas or Cord PH  is a lab test which is done at the time of delivery.  A nurse will take a small sample of blood from the umbilical cord and have the lab run a PH test on it.   Normal PH is usually around 7.25.  

If the Cord Blood sample has a PH lever much lower than normal,  it can indicate there was a problem with oxygenation during labor and delivery.   Another value which is measured is the Base Excess.   If this number is above 12,  it too can indicate a problem with oxygenation of the baby during labor and delivery.
