This is a normal variation due to stress of labor
The level of white blood cells in the body vary due to the amount of external stress that is placed on the body. The level indicated, 22,000/mm³ is within this range, which extends up to 30,000/mm³ for women after delivery. Because this is well within the normal range, there is no need to retest the value obtain neither is there a need to administer antibiotics.
