A group of American and Danish doctors have developed a non-invasive and inexpensive method that allows you to determine the duration of pregnancy with an accuracy comparable to ultrasound.. Determining the gestational age is carried out using a blood test for the content of extracellular RNA characteristic of the placenta. New method with 75% accuracy indicates possible preterm birth.

Doctors have learned to determine the duration of pregnancy and premature birth. Now the most common ways to determine pregnancy are ultrasound, which is quite expensive, or the time of the last period, which can be inaccurate.. None of these methods are predictive of preterm birth.. An international team of physicians led by Stephen Quake of Stanford University has proposed a unique, non-invasive and inexpensive method, which consists in a blood test for the content of extracellular RNA of the embryo, placenta and maternal immunity.. The ability to predict preterm birth cannot be overestimated:

about 15 million babies worldwide are born prematurely, which is the most common cause of newborn death.

By analyzing the composition of extracellular DNA and RNA, it is possible to diagnose the rejection reaction of a transplanted organ, use them as a biomarker for diagnosing and evaluating the effectiveness of cancer treatment.

Recently, doctors described a rather rare case when doctors, supporting the functioning of vital organs after the death of the brain of a pregnant woman, were able to save a child..
