Home tests can tell you if you are pregnant, but can it tell you that you have twins or abortions? Based on the detection of protein in the urine of women, the use of arithmetic to predict pregnancy outcomes will become a reality.
This year's pregnancy test kit allows a woman to know if she is pregnant and how long she has, but there are still many uncertainties. Three-quarters of abortions occur within the first three months of pregnancy, and many women do not announce their pregnancy until after this period. But this situation is about to change, because the MAP company in Hertfordshire, England, has invented a test method. "We want to tell our parents that they have a chance to have a healthy baby," said Stephen Butler, founder of the company.
This test analyzes the protein content of women's urine and predicts the probability of successful fertility, miscarriage, pre-eclampsia, and twin birth. This test was inspired by in vitro fertilization. Traditionally, healthy embryos have been selected by the naked eye and implanted in women who use the therapy. Some new methods are to take a cell from each early embryo and use genetic testing to detect the number of abnormal chromosomes, or genetic variants associated with undesirable pregnancy outcomes, but these tests are expensive, invasive, and may be erroneous. And other issues. "Non-invasive testing is a method of constant search." Spanish IVI Foundation Francisco Dominguez said he had tried to predict fetal health using proteins collected from embryos.
To make predictions, the team collected 121 samples of women between the ages of 6 and 10 weeks. By identifying the protein characteristics in these samples, this operation can find patterns associated with abortion symptoms. The researchers reported the results at the annual meeting of the European Society for Human Reproduction and Embryology in Lisbon, Portugal, in June.
Other calculations can predict twins, or chromosomal abnormalities that may exist in the fetus. But before the results were popularized and made into family suits, the team wanted to carefully verify these calculations. For example, they planned to analyze 10,000 samples to improve the screening ability for chromosomal abnormalities in Down's syndrome.
