When do leukocytes return to pre-pregnancy levels?

When do leukocytes return to pre-pregnancy levels?

• A. Six days postpartum
• B. At term
• C. Two weeks postpartum
• D. Immediately after delivery

Answer: (A)

Leukocytes rise in pregnancy as a normal physiologic response and tend to stay elevated during labor. After delivery, the immune system shifts back toward the nonpregnant state, and the leukocyte count falls back toward pre-pregnancy levels. In uncomplicated pregnancies, this normalization typically happens within the first week after birth, commonly around day 5 to day 7. Six days postpartum is a practical point at which leukocyte counts are often back to baseline. If an infection or postpartum complication occurs, leukocytosis may persist or rise again, signaling the need for evaluation.
