Understanding Lab Tests for Pregnancy and Breastfeeding
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Pregnancy and breastfeeding are natural physiological states that involve significant hormonal changes in a woman's body. While pregnancy is typically confirmed through pregnancy tests and breastfeeding success is measured by infant growth, blood tests play a crucial role in monitoring hormonal balance and detecting potential complications during these important life stages.
Recommended Test
Prolactin
Prolactin is a hormone essential for milk production and is naturally elevated during pregnancy and breastfeeding. Testing prolactin levels helps monitor normal hormonal function during these periods and can detect abnormally high or low levels that may indicate underlying hormonal disorders or complications affecting breastfeeding capacity.

Why Hormonal Monitoring is Important
During pregnancy and breastfeeding, hormone levels fluctuate dramatically to support fetal development and milk production. Blood testing helps healthcare providers monitor these changes, ensure proper hormonal function, and identify any abnormalities that could affect maternal health or breastfeeding success.
Understanding Prolactin During Pregnancy and Breastfeeding
Prolactin levels naturally increase during pregnancy to prepare the breasts for milk production and remain elevated throughout breastfeeding to maintain milk supply. However, monitoring these levels through blood testing can help identify situations where prolactin is too high or too low, which could indicate hormonal imbalances or other health concerns.
