Non-invasive procedures for prenatal diagnosis are the most frequently used methods in the first trimester of pregnancy in pregnant women under 35 years of age because they do not involve risk of pregnancy loss; however, they are not considered to be a definitive diagnosis method.

However, the definitive diagnosis is performed by cytogenetic analysis through amniocentesis. Thirty what is blood test in pregnancy, under 35 years of age with high-risk pregnancy, were studied with duo test and structural ultrasound in the first trimester and amniocentesis in weeks 15— Only five duo tests were positive: three showed risk of trisomy 18 and one of Turner syndrome, they all corroborated with the cytogenetic study; the fifth showed a risk of Down's syndrome, however it was a chromosomally normal product.

Three patients with a negative duo test cytogenetically detected with karyotypes with structural abnormalities, which were: deletion of the short arm of chromosome 18 [46,XY, del 18 p11 ], Robertsonian translocation between chromosome 13 and 14 [45,XY, rob ] and a chromosome derived from X [46,X, der X ]. The duo test is a very useful tool for the diagnosis of numerical what is blood test in pregnancy abnormalities, but not for detecting structural chromosome aberrations.

However, it is essential to perform amniocentesis to definitively rule out chromosomal aberrations in products of conception. Prenatal diagnosis, using invasive procedures such as amniocentesis and chorionic villus sampling, in women with a high risk of having babies with chromosomal and structural abnormalities 1 is a very useful tool which is widely used nowadays.

However, these invasive procedures involve a significant risk of miscarriage 1 in Currently, non-invasive procedures are considered to be a very useful tool for making decisions with regard to the what is the purpose of bootstrapping in phylogenetic analysis of pregnancies with genetic diseases.

The quadruple marker test is performed between weeks 15 and 20 of pregnancy. Subsequently, the duo test was established. This is performed in the first trimester of pregnancy 11— The duo test is complemented by the fetal ultrasound which measures nuchal translucency and nasal bone. A non-invasive prenatal diagnosis test based on next-generation what is blood test in pregnancy NGSwhich consists of the analysis of cell-free fetal DNA in maternal blood, has recently been developed. This procedure is increasingly gaining importance in the screening for chromosomopathy, especially in trisomies 21, 18 and Amniocentesis should be directly indicated for patients over 35 years of age, in whom biochemical markers do not have a relevant use for predicting aneuploidy in products of conception.

The objective of this study is to identify the use of the duo test in detecting numerical chromosomal abnormalities in patients under 35 years of age in a sample of Mexican women with high-risk pregnancy who came to the Hospital General de México. This project consisted of a descriptive, comparative study, with analysis, using a two-by-two table, between the duo test and amniocentesis. The sonographic markers of chromosomopathies were used in accordance with the criteria of the Fetal Medicine Foundation.

In all cases, the karyotype test which of these is an example of maintaining boundaries performed in amniotic fluid using amniocentesis between weeks 15 and 18 of pregnancy. The GTG banding technique and a chromosome analysis using conventional methods were performed. The statistical analysis consisted of descriptive statistics and a two-by-two table to determine sensitivity and specificity.

Five of the 30 duo tests performed on women with high-risk pregnancy showed an increased risk of chromosomopathy. Of the five cases, three showed a risk of trisomy 18, one of Down's syndrome trisomy 21 and one of Turner syndrome X chromosome monosomy. These conditions were confirmed in four of the five cases using cytogenetics: three of trisomy 18 and one of Turner syndrome; the other potentially Down's syndrome was a normal chromosomal fetus. It is worth mentioning that the duo test does not make it possible to differentiate between these types of structural chromosomal abnormalities.

The sensitivity and specificity of the duo test with regard to the result of the karyotype is summarized in Table 1. Patients with positive chromosomal abnormalities detected using cytogenetics and their relation with the analysis of the duo test. Prenatal analysis by means of a karyotype in amniotic fluid is a reliable method for checking for aneuploidy and other structural chromosomal abnormalities.

It is a method which should be indicated directly for women over 35 years of age, given the increased risk of them having babies with numerical chromosomal abnormalities. As for women under 35 years of age, it is preferable that a non-invasive method be carried out initially, since performing an amniocentesis carries the risk of miscarriage 1 in However, no increased risk of chromosopathies in patients whose karyotype presented a structural abnormality was found.

This means that it is not possible to rule out structural chromosomal abnormalities using the duo test determination. Sensitivity what is pedigree dog food made of specificity of the duo test. The gold standard is the karyotype in amniocentesis. There are currently other non-invasive techniques which enable the screening of another series of defects present in the fetus.

These are not covered in this study. In conclusion, in this study we have managed to identify an increased risk of having babies with numerical and structural chromosomal abnormalities in patients under 35 years of age using the duo test and amniocentesis. This denotes the importance of performing these types of studies in pregnant women regardless of their age, since why do dogs love eating sticks an accurate diagnosis of the baby's normality gives a couple peace of mind during the pregnancy.

If an abnormality is detected, genetic counseling will allow the couple to make the decision that is best for them.
