Centers for Disease Control and Prevention. Our Healthcare Expert will be answering some questions every week but in the meantime, here's a little tip from our Careline! The mean platelet count in the 8885 nonpregnant women is designated by N on the x axis. Research notes that: Mental stress can impact platelet count and function. At the time of delivery, 9.9% of the women with uncomplicated pregnancies had a platelet count below 150,000 per cubic millimeter. This results in increased blood volume and causes hemodilution. Most women who have essential thrombocythemia have normal, healthy pregnancies. Background: Platelet counts of less than 150,000 per cubic millimeter during uncomplicated pregnancies are described as gestational thrombocytopenia if no alternative cause is identified. Pregnancy-related complications, such as pre-eclampsia, may also cause thrombocytopenia.4,810 Therefore, it may be hypothesized that platelet counts in women who have pregnancy-related complications are lower than platelet counts in women who have uncomplicated pregnancies. Assuming that platelet counts measured in the women during the postpartum period were similar to their platelet counts before pregnancy, mean platelet counts decreased by an estimated 17% during pregnancy. Therefore, the risk of a platelet count below 150,000 per cubic millimeter was 14.2 (95% CI, 8.9 to 22.6) times as high among women who had had a count below 150,000 per cubic millimeter in a previous pregnancy as among women who had not. As the spleen increases in size due to increased blood volume during pregnancy, it may destroy more platelets in the filtering process. There are two main types of thrombocytosis: essential thrombocythemia and reactive thrombocytosis. J Clin Med Res. Certain individuals are more at risk of developing clots, including those who: Blood clots may form in any blood vessel and prevent blood from flowing properly.

Pooling of platelets in the spleen: role in the pathogenesis of hypersplenic thrombocytopenia. However, an abnormally high number of platelets in pregnancy is far less common than low platelet levels, and the causes could range from infection, medication, disease or inflammation. Both conditions usually occur during the later stages of pregnancy, or soon after childbirth. A high test result means that your platelets are larger than what's considered normal. Surgeries and trauma can lead to a high platelet count. take care! If you have HELLP syndrome once, your risk increases for having it again. Platelet counts as low as 43,000 per cubic millimeter4,21 were reported previously in patients with gestational thrombocytopenia, but no information describing a search for an alternative cause was provided.21 Our data suggest that, for women with an uncomplicated pregnancy who have a platelet count of less than 100,000 per cubic millimeter, a cause of thrombocytopenia other than the pregnancy itself should be considered. 1). The interaction between the mean platelet count in the women with uncomplicated pregnancies and the mean platelet count in the women with pregnancy-related complications was significant (P = 0.002), which indicated that the rates of decrease in platelet counts differed. Your healthcare team will make sure that your diagnostic tests are safe for you and your baby. The site is secure. Inflamm Bowel Dis. ACOG practice bulletin no. . Placenta previa: a 22-year analysis.

The combined mean platelet counts from all studies supported the concept . Platelets and pregnancy. S1A and S1B in the Supplementary Appendix). Platelet counts of less than 80,000 per cubic millimeter for which an alternative cause was not identified occurred in only 5 women (0.1%), none of whom had a platelet count below 62,000 per cubic millimeter. A high platelet count, or thrombocytosis, is defined as having more than 450,000 platelets per microliter of blood.

HELLP syndrome is a rare pregnancy complication. In other cases, there may be a problem like an infection or anemia. The mean and median platelet count values for each of the three distribution curves differed by less than 3%. HELLP stands for hemolysis (the destruction of red blood cells), elevated liver enzymes and low platelet count. For example, spleen removal surgery, or a splenectomy, is significantly associated with secondary thrombocytosis, impacting up to 90% of individuals who undergo this procedure. If you already have a platelet disorder, pregnancy may make your condition worse. Usually, thrombocytosis isn't serious.

Even for those of us who are healthy, we need to find a doctor who can help us get through the emotional transitions during pregnancy and beyond. The symmetric distribution of mean platelet counts seen in the nonpregnant women and also in the women with uncomplicated pregnancies in their first trimester and at the time of delivery suggests that the platelet counts of all women with uncomplicated pregnancies decrease at the same rate. Inclusion in an NLM database does not imply endorsement of, or agreement with, Of the 472 women who did not have a platelet count below 150,000 per cubic millimeter in their initial pregnancy, only 21 (4.4%) had a platelet count below 150,000 per cubic millimeter at the time of delivery in their subsequent pregnancy.

When all the women with uncomplicated singleton or twin pregnancies who had a platelet count at the time of delivery (8051 women with singleton pregnancies and 93 with twin pregnancies) were evaluated, the mean platelet count in the women with twin pregnancies (197,000 per cubic millimeter; 95% confidence interval [CI], 182,000 to 212,000) was significantly lower than the count in the women with singleton pregnancies (214,000 per cubic millimeter; 95% CI, 213,000 to 215,000) (P = 0.03) at the time of delivery. The data from the women who had uncomplicated pregnancies were compared with the data from 8885 nonpregnant women from the NHANES database. The two types of thrombocytosis are primary thrombocytosis and secondary thrombocytosis: A high platelet count may be found during routine blood work and more tests may be done to diagnose any associated conditions. Regularly exercising helps maintain platelet function when at rest. The normal range for WBC count during pregnancy is between 5,000 and 15,000 cells/mcL (microliter) of blood.
