saliva test predicts risk of preterm delivery
A simple saliva test could help to reduce premature births potentially dangerous.
The test, developed at King's College London, finds that pregnant women could give birth prematurely their baby by measuring their levels of progesterone , the ' hormone that helps stop the contractions of the womb before the end 40 weeks.
Women with low hormone levels are those at risk of giving birth to more than six weeks in advance.
Thanks to the test, scientists are convinced, you can reduce premature births, before 37 weeks of gestation, who are most at risk of medical complications, learning difficulties and other disabilities.
Women through the simple saliva test will be most at risk will be monitored with more attention and help, if necessary, with additional strong doses of hormones .
" Saliva is easy to pick - says the head researcher Lucilla Poston of King's College London - there is no need for a needle or a sample of blood and would be wonderful if in the future, we may ask a pregnant woman to give us just a small saliva sample to determine if a premature birth risk .
Researchers at King's College London analyzed the saliva samples of 92 women between 24 and 34 weeks of pregnancy.
The mothers were identified as being at risk of preterm birth to have had previous miscarriages, premature births or infections.
progesterone levels were lower in the saliva of 12 women who gave birth prematurely. The study was published in the ' BJOG: An International Journal of Obstetrics and Gynaecology '.
