How low can your iron levels be when you go into labor?

Can or should?: Your iron levels can potentially get very low if you're actively losing iron (such as ongoing bleeding). Perhaps you are asking how low they should be? You don't want to go into labor already severely anemic. That is the biggest issue, because blood loss is expected at delivery. If your hemoglobin level is less than 10 or your hematocrit is less than 30, i would suggest iron supplementation.

>9 g/dL.: Your hemoglobin should be >9 g/dl when entering labor & delivery, in general. If you have an increased risk of bleeding at delivery (e.g. Placenta previa, accreta, platelet disorder, blood thinner) your hemoglobin should be >11 g/dl and blood available for transfusion as needed. Best of luck!
