What is the expected hemoglobin value for a pregnant woman during the third trimester?

During the third trimester of pregnancy, the expected hemoglobin value typically ranges from 11.0 to 11.5 g/dL. It is important to recognize that during pregnancy, there is an increase in plasma volume, which can dilute hemoglobin levels. This phenomenon is referred to as hemodilution, and it is quite common in pregnant women. While values lower than this range may indicate anemia, a hemoglobin level of approximately 11.5 g/dL is often considered a normal finding for women in the later stages of pregnancy.

Selecting 11.5 g/dL reflects an understanding of this physiological adaptation and the normal adjustments that occur during pregnancy, especially in the context of increased cardiovascular demands on the body. This level indicates an adequate supply of hemoglobin to meet both the mother’s and the fetus's oxygen needs without signaling anemia in this particular period.
