Can I have liver and kidney function tests during my menstrual period?

Liver and kidney function tests conducted during the menstrual period may be subject to certain influences. On one hand, hormone and metabolic levels in women's bodies change during menstruation, especially fluctuations in estrogen and progesterone. These changes may affect liver and kidney function, leading to temporary abnormalities in test results. On the other hand, physiological phenomena such as water and sodium retention or blood loss may also interfere with liver and kidney function test outcomes. However, since liver and kidney function tests usually require fasting blood samples, and this requirement is not significantly affected by menstrual cycle-related physiological changes, undergoing such tests during the menstrual period generally does not impact the results. To ensure accuracy, it is recommended to schedule liver and kidney function tests outside the menstrual period. If testing must occur during menstruation, inform your physician about your menstrual status and ensure adequate rest before the test, avoiding strenuous activity and emotional fluctuations.
