Platelets are responsible for blood clotting and play a significant role during pregnancy as well.

Pregnancy platelets normal range. In normal pregnancies the platelet count decreases from the beginning to the end of the pregnancy from an average of 260k to about 220k per cubic millimeter. The average or normal platelet count of a non pregnant woman may range between 150 000 and 400 000 per microlitre of blood. There is a normal drop in platelet count during pregnancy. It is not known exactly why it occurs but it is thought to be a result of the increased blood volume as your pregnancy progresses to full term.

Thrombocytopenia is present in about 5 8 of all pregnancies. Normal platelet count in pregnancy. The actual amount may also vary among different parts of the body.

There may be differences among sources on the exact standard normal platelet count but should be within the range of 150 000 to 450 000 for every microliter of blood. Some common causes of low platelets during pregnancy include gestational thrombocytopenia pre eclampsia hellp hemolysis elevated liver enzymes low platelets syndrome immune thrombocytopenic purpura itp. Less common causes include systemic lupus erythematosus lupus anticoagulant human immunodeficiency virus hiv infection b12 or folate deficiency hyperthyroidism massive. In the first trimester the normal count is around 250 000 and decreases to about 225 000 at delivery.

Platelet counts 100 000 were rarely encountered in normal uncomplicated pregnancies and should not generally be considered a physiologic change.
