The Pregnancy Test Every Woman Should Know About ft. Zhenya Lindgardt & Dr. Tiffany Inglis

Following the overwhelming response to the Hailey Bieber episode, SHE MD sits down with Sera Prognostics CEO Zhenya Lindgardt and Chief Medical Officer Dr. Tiffany Inglis for a powerful, science-backed conversation about preterm birth, maternal health, and the pregnancy blood test most women, and most doctors, have never heard of. They unpack how a simple test taken between 18 and 20 weeks can predict and help prevent preterm birth in women who would otherwise be considered "low risk."
This conversation goes deep into the science behind the PreTRM test and the two proteins it measures. The doctors explain why other current screening methods miss nearly 80% of women who will go on to deliver prematurely, and how the preTRM® test is changing maternal care from reactive to preventive. They break down the role inflammation and placental health play in pregnancy, and how the preventive protocol used in the PRIME study helped reduce early preterm births by 56%. They also dive into the emotional, physical, and financial toll of NICU stays, disparities in maternal healthcare, and why women need better access to personalized pregnancy care.
This episode is ultimately about agency: knowing your individual risk, advocating for the care you deserve, and shifting maternal medicine from reactive to preventive. Whether you're pregnant, planning to be, or supporting someone who is, this conversation delivers the science, the resources, and the mindset shift that could change the trajectory of a pregnancy and the lives that depend on it.
