Gestational thrombocytopenia is a common and usually benign condition in pregnancy, but additional tests may be ordered to confirm the diagnosis and rule out other causes. Routine blood tests can reveal early warning signs of complications, but a drop in platelet levels is often normal in pregnancy. Patients with gestational thrombocytopenia are asymptomatic and have no history of bleeding during pregnancy. If a patient meets all diagnostic criteria, they likely have gestational thrombocytopenia, but monitoring may be necessary to detect any changes or complications.
Gestational thrombocytopenia is a low platelet count in pregnancy that is usually benign. It is the leading cause of thrombocytopenia in pregnancy and is by no means uncommon, although a patient’s obstetrician may order some additional tests to confirm the diagnosis and rule out other possible causes of a low platelet count. This test ensures that the patient will receive the most appropriate care. Typically, women with gestational thrombocytopenia can deliver vaginally and should be at no additional risk in pregnancy due to their platelet counts, although other medical conditions can create complications.
Routine blood tests during pregnancy can reveal a drop in platelet levels, potentially showing early warning signs of complications that need to be addressed to protect the health of the mother and fetus. Abnormalities in test results, however, aren’t an immediate cause for concern, as there may be benign explanations. In the event that a test shows a problem such as a decrease in the patient’s platelets, the next step is more tests to determine what is going on, to see if any action needs to be taken.
Some drop in the total number of platelets tends to be normal in pregnancy. Women produce a greater volume of plasma and consume platelets more rapidly during pregnancy. In some cases, this causes the platelet count to drop below the diagnostic threshold for thrombocytopenia. Patients with gestational thrombocytopenia are asymptomatic and have no history of bleeding during pregnancy, indicating that the low platelet count is not causing any problems.
Another important diagnostic criterion for this condition is the absence of a history of thrombocytopenia. Blood tests done before pregnancy should reveal a normal platelet level, indicating that the patient usually has healthy blood chemistry. Thrombocytopenia should also be mild to moderate; severe drops in platelet levels are a cause for concern because they are associated with other conditions. Also, the fetus should be healthy, with no signs of distress.
If a patient meets all of these criteria, they likely have gestational thrombocytopenia rather than a more serious platelet-related condition. The last criterion is difficult to verify during pregnancy, as it involves waiting several weeks after delivery and having the patient’s blood tested to confirm that platelet levels have returned to normal. Patients with cases of gestational thrombocytopenia may be monitored to see if they develop symptoms or if their platelets continue to fall, both indicators that something more serious is going on and intervention may be needed.
