The fetal lung maturation test in pregnancy


Technology advances, and many times it does so at the service of medicine. This is positive, without a doubt, since each time we find new non-invasive formulas to detect possible abnormalities in the fetus During pregnancy.

The lung maturation test is able to determine the development of the fetal lungs and compare it with the rate of maturation that it should have depending on the week it is in. It is a non-invasive and very effective test to determine the percentage of survival that the baby would have if it were born early. We explain what the lung maturation test in pregnancy is and what it offers us.

The fetal lung maturation testis a non-invasive diagnostic test that is performed on the pregnant woman by means of an ultrasound. It is also known as the quantusFLM test, and it is relatively recent (it has started to be used in Barcelona, ​​Spain).

The quantus test uses computer software that measures, thanks to ultrasound, the lung texture of the fetus. Taking into account the gestational age, this test determines the maturation of the fetal lungs and the risk of mortality of the baby in the case of premature birth.

The system used by the quantusFLM test is the analysis of the fetal lung area, using images of the baby collected in 2D ultrasounds.

The degree of lung maturation of the fetus is also offered by another test, amniocentesis (for this the fluid of the amniotic fluid is measured). But nevertheless, this test offers great advantages over amniocentesis: while the lung maturation test is performed non-invasively by means of a simple ultrasound scan in just 10 minutes, amniocentesis is still an invasive and dangerous test for both the patient and the patient. baby as well as for his mother, which also means a longer wait to know the results and the need for the mother to remain completely resting after the test for a few days.

The lung maturation test informs us of the risk of mortality for the baby in the event that it is born prematurely. In other words, if a 28-week pregnant woman were to go into labor or had to induce labor for health reasons, this test could determine her baby's chances of survival. Based on the results, it could be determined if it is convenient (if it can be) to wait a little longer or not.

What the test will determine after the relevant analyzes, is if the baby is ready to breathe, since the lungs are one of the organs that take the longest to mature during gestation and one of the main causes of mortality among premature babies.

In this way, thanks to this test, if any abnormality occurs during pregnancy, the gynecologist would have more data when deciding whether or not to induce labor early.
