The PreTRM Test is an innovative blood test that your doctor can order, or that can be requested online, during weeks 18 through 20 of your pregnancy. The test measures proteins in the blood that predicts your individual risk of delivering early. The report will provide information on your individual risk for premature delivery, so you can work together, with your doctor, to adjust your treatment plans accordingly.

WHAT CAN YOU DO TO UNDERTSTAND THE RISK?
1 in 10 babies are born too soon.

Do I Qualify for the Test?
PreTRM can be used to identify your risk of preterm delivery if you:
- Are 18 years old or older
- Are pregnant with a single baby (not twins, triplets, or other multiples)
- Are not currently showing signs of preterm labor
- Are not on progesterone therapy after the first trimester of your pregnancy
- The baby has no confirmed or expected genetic condition or disorder that is associated with shortened gestation


What Information Is Provided by the PreTRM Test?
- General risk of preterm birth for all singleton pregnancies: 7.3%
- Your individualized risk for preterm birth: X% based on the PreTRM test
The report also compares your personal risk for preterm birth to the average risk of all women pregnant with a single baby. For example, a pregnancy with a 22% individualized risk percentage would be three times as likely as average to deliver before 37 weeks.
With the risk information from the PreTRM Test, along with other vital information from your prenatal visits, you and your healthcare provider can personalize your pregnancy care to optimize your treatment plan and offer the best possible care for your baby.
