Can the Risk of Preterm Birth Be Detected in Advance?
Yes. With today’s advanced prenatal monitoring methods, the risk of preterm birth can often be predicted early—and in many cases, preventive steps can be taken. To achieve this, clinical history, ultrasound findings, and laboratory tests are evaluated together.
Key Screening Tests
- Cervical Length Measurement (Transvaginal Ultrasound):
Performed between 20–24 weeks of pregnancy, this is one of the most important indicators for assessing the risk of preterm birth.
- A cervical length below 25 mm indicates an increased risk.
- Fetal Fibronectin (fFN) Test:
This test measures the presence of a protein found in the cervix that increases as labor approaches.
- Conducted between 24–34 weeks, it helps estimate the likelihood of delivery within the next 1–2 weeks.
- Infection Screening (UTI, Bacterial Vaginosis, Ureaplasma, etc.):
Silent genital or urinary infections are among the most common causes of preterm birth.
- Culture and PCR tests are recommended when clinically indicated.
- Uterine Contraction Monitoring (NST or Wearable Home Devices):
Unnoticed uterine contractions can be early warning signs of preterm labor.
- Especially useful for women with a previous history of preterm birth.
What Do Ultrasound Findings Reveal About Preterm Birth?
Modern ultrasound technology allows for detailed observation of both cervical structure and fetal development. The following findings may indicate an increased risk of preterm birth:
- Cervical funneling: A funnel-shaped opening at the internal cervix, signaling early dilation.
- Dynamic cervical shortening: Cervical length changes depending on uterine position, suggesting possible cervical weakness.
- Increased amniotic fluid (polyhydramnios): Raises intrauterine pressure, which can trigger preterm contractions.
Our Advanced Monitoring Approach
Under the guidance of Prof. Dr. Arda Lembet, an expert in high-risk pregnancies, our clinic carefully manages preterm birth risk through the following practices:
- Routine cervical length measurement for all patients between 20–24 weeks.
- Serial measurements for high-risk cases to track cervical changes dynamically.
- Use of fetal fibronectin and cervical infection tests at regular intervals or when clinically indicated.
- Individualized delivery planning through multidisciplinary decision-making.
- An interactive patient tracking system that continuously monitors each woman’s risk profile and enables early intervention.
Measure. Monitor. Prevent.
While it may not always be possible to predict preterm birth with absolute certainty, modern screening methods and experienced clinical follow-up make it possible to detect and manage risks before they escalate.
The most important step in this process is timely measurement and a personalized monitoring plan tailored to each patient’s unique clinical profile.
