Now that you’re pregnant, or considering pregnancy, you know that certain things you once took for granted—like sleep, me time, even clean laundry—will become rare.

But one thing that isn’t rare is preeclampsia.

What is preeclampsia?

Preeclampsia is a serious disease related to high blood pressure that usually occurs in the second half of pregnancy. Preeclampsia affects 5–8%1,2 of all pregnancies and can happen to any woman, during any pregnancy.

What is early onset preeclampsia?

When high blood pressure results in the delivery of a baby before 34 weeks of pregnancy, it’s called “early onset preeclampsia” and is often a more dangerous form of the disease. Left untreated, it can lead to life-threatening complications for both you and your baby.

That’s why it’s important to talk to your doctor about how you can be screened for early onset preeclampsia.

Am I at an increased risk?*

Because preeclampsia can affect any pregnancy, all women should consider screening. However, the following risk factors may increase your chances of developing it.

  • First pregnancy
  • You or a close family member has had preeclampsia
  • Advanced maternal age
  • Pregnant with more than one baby (e.g., twins)
  • Fertility treatment
  • History of obesity, hypertension, diabetes, renal disease, blood disorders or lupus

What are the symptoms?*

Preeclampsia symptoms can disguise themselves as normal pregnancy symptoms, so being aware of them is key. Some symptoms include:4

Earlier insight means more opportunity

PreeclampsiaScreen | T1 is a first-trimester screening test that measures the presence of three biological “markers” in your blood. When detected at certain levels, these markers can indicate a higher risk of developing early onset preeclampsia.

A high-risk test result gives you the chance to take some easy steps to manage your pregnancy.

PreeclampsiaScreen | T1 analyzes three biochemical markers: PAPP-A (pregnancy-associated plasma protein-A), PlGF (placental growth factor) and AFP (alpha fetoprotein). Together, these three biochemical markers, along with a special sonographic and blood pressure measurement, can contribute to accurate prediction of risk for early onset preeclampsia in the first-trimester. Pregnant women can take the test as early as 11 weeks. It has a 91% detection rate and only a 5 percent false positive rate.

The PreeclampsiaScreen | T1 test has been reviewed and approved by the New York State Department of Health. To view the validation paper, please click here.
