[2025-09-29T16:00:09.079307] [PI reasoning] **Determining iron depletion tests**

The user is asking which test is most sensitive for detecting iron depletion during pregnancy. I think serum ferritin is likely the best answer because it reflects body iron stores and tends to decrease before anemia occurs, making it an early indicator of iron deficiency. I should provide evidence to support this, so I plan to look up information on serum ferritin's sensitivity regarding iron depletion in pregnancy. I'll make sure to cite relevant evidence as well.
