Various discoveries are being made to ensure that pregnant women do not face any problems. Now Australian scientists have discovered a new type of blood test which can prove to be very helpful for pregnant women. 

New blood test For pregnancy complications: A team of Australian scientists has developed a new type of blood test that can detect health complications in the early stages of pregnancy. The research team from the University of Queensland said in a study published on 27 February 2025 that their "nanoflower sensor" could help reduce hospitalizations for newborns, Xinhua news agency reported.  

How does this test work?

This test checks blood samples for cell biomarkers and can detect complications such as gestational diabetes, risk of preterm birth and high blood pressure as early as 11 weeks into pregnancy.

Carlos Salomon Gallo, from the University of Queensland's Centre for Clinical Research, said the team tested the sensor on blood samples from 201 pregnant women at 11-13 weeks' gestation and looked for potential complications.

What did the experts say?

Gallo said, "Currently, most pregnancy complications cannot be identified until the second or third trimester, which means it may sometimes be too late for effective intervention. However, this technology will allow pregnant women to receive medical interventions much earlier. We also found that our biosensor has more than 90 percent accuracy in identifying women at risk of developing pregnancy complications." 

Researchers said the technique could save healthcare systems millions of dollars each year by reducing admissions to the neonatal intensive care unit and preventing emergency pregnancy interventions, including cesarean sections. "It has the potential to revolutionize early risk assessment and interventions, improving decision making in obstetric care," Gallo said.

Pregnant women will get help

Mostafa Kamal Masud, co-author of the study from the Australian Institute for Bioengineering and Nanotechnology at the University of Queensland, said the technique used nanosensors to detect low concentrations of biomarkers that indicate potential health complications, which cannot be detected by existing less sensitive testing methods. This research has been published in the journal Science Advances.
