During what postnatal period would you expect to see Alba lochia and what color is it?

Alba lochia refers to the final stage of lochial discharge that occurs after childbirth. It typically appears approximately 11 to 21 days postpartum and is characterized by a white or yellowish-white color. This discharge consists mainly of leukocytes, tissue debris, and mucus, indicating the body's return to a non-pregnant state as it continues to heal.

In the earlier stages of lochia, such as rubra (red) and serosa (pink or brown), the discharge reflects more blood and tissue as the uterus undergoes significant changes in the immediate postpartum period. However, by the time alba lochia occurs, the composition shifts to primarily white blood cells and fluid, marking a reduction in the volume and a change in color, which distinguishes it from previous stages. Therefore, the identification of alba as occurring between 11 and 21 days postpartum and presenting as white aligns with the physiological understanding of lochial changes following childbirth.
