Prenatal ultrasonographic diagnosis of caudal regression syndrome is possible at 22 weeks' of gestation by ultrasound examination.
In sirenomelia third-trimester ultrasonographic diagnosis is usually impaired by severe oligohydramnios related to bilateral renal agenesis, whereas during the early second trimester the amount of amniotic fluid may be sufficient to allow diagnosis.
Early antenatal sonographic diagnosis is important in view of the dismal prognosis, and allows for earlier, less traumatic termination of pregnancy [5].

 Prenatal Diagnosis - Patient UK
The primary aim of a prenatal diagnosis is to provide an accurate diagnosis that will allow the widest possible range of informed choice to those at increased risk of having children with genetic disorders or with congenital abnormalities.
Prenatal MRI is also used to assess fetuses with spina bifida, look for associated malformations, and along with ultrasound scanning help to predict neurological deficit and ambulatory potential.
Prenatal diagnostic accuracy is improving but as one UK study showed, may be lower than many clinicians assume and the public expects for some important conditions such as diaphragmatic hernia, bladder outlet obstruction and major skeletal defects in which detection rates prenatally were still less than 70%.

She told me that the diagnosis was a big shock to her, but as long as he was with us, we might as well enjoy him.
I believe that expectant moms whose babies have a prenatal diagnosis should have the same option to 'study up' with mainstream baby books as well as the best information on Down syndrome, and also to take a break from all that to enjoy her pregnancy.
If a baby was prenatally diagnosed with blue eyes, and friends and family immediately looked up all information about the disadvantages of having blue eyes to present to the mother during her pregnancy, we would feel that is inappropriate, even though people with blue eyes do have special health care considerations and problems.

Prenatal diagnosis (testing for the fragile X mutation in a baby before it is born) is available to any person shown to be a carrier of a fragile X mutation.

  Ultrasound Prenatal Diagnosis of Fetal Malformations: Hospital- Based Screening and Necropsy Study - Health - RedOrbit   (Site not responding. Last check: )
In the prenatal area the main aim of necropsy is to specify the kind of pathology suffered by the embryo or fetus, the findings being compared with the information provided by the various prenatal diagnostic techniques used and the presence of any other abnormalities being ruled out [10].
Reliable diagnosis depends on the kind and the quality of the necropsy which is directly related to the experience of the pathologist and his/her knowledge of developmental pathology.
The correlation between the data provided by prenatal diagnosis (cytogenetic, ultrasound, serological, etc.) and the results of necropsy is of fundamental importance in terms of controlling the quality of the former; indeed, its role as a method of audit seems clear [25].

Prenatal diagnosis - that is, testing for abnormalities in unborn babies - has become an almost universal part of pregnancy care in Australia in 1999.
While prenatal diagnosis is said to be economically cost-effective, especially for conditions where a child would require constant and ongoing support and supervision, the 'cost' to women and their families of this new technology is not often explored.
Prenatal diagnosis is based on the assumption that discovering and terminating an affected pregnancy is advantageous, even when the condition detected would be lethal to the baby at a later time.

 Dangers of Prenatal Diagnosis - Catholic Online
Prenatal diagnosis is very useful to be able to determine a good number of fetal pathologies; many of these can be treated, some directly before birth.
So a distinction must be made between a prenatal diagnosis done in the interest of all the individuals -- embryo-fetus and mother -- and one which, instead, considers only the interests of the one already born.
Pregnancy must be released from the grip of anxiety, and prenatal diagnosis must be given back its role as coadjutor of a mental and emotional process, and not as an obligation for social ends.

 The Morality of Prenatal Diagnosis
Prenatal diagnosis (also known as prenatal genetic testing) -- procedures such as amniocentesis, chorionic villus sampling (CVS), maternal serum alpha-fetoprotein (AFP) and ultrasonography -- in and of itself, is not evil.
Such diagnosis is permissible...if the methods employed safeguard the life and integrity of the embryo and the mother, without subjecting them to disproportionate risks.
But this diagnosis is gravely opposed to the moral law when it is done with the thought of possibly inducing an abortion depending upon the results....

 Prenatal diagnosis   (Site not responding. Last check: )
Chorionic villus sampling is a prenatal diagnosis procedure which involves analysis of the chromosomes in the placenta.
Amniocentesis is a prenatal diagnosis procedure which involves chromosome analysis of cells in the amniotic fluid which are cells from the baby.
This is because we know that babies with trisomy 15 or 16 cells cannot survive, so if trisomy 15 or 16 is found at prenatal diagnosis it is less likely to indicate the presence of the abnormal trisomic cells in the baby.

They made a prenatal diagnosis of tetrasomy 12p from amniocytes, using the R-banding technique and the study of gene dosage effects for SOD1 and LDH-B, after an ultrasound study was carried out first.
Diagnosis based on clinical appearance alone is often difficult due to the broad spectrum of clinical anomalies not specific to this syndrome.
Differential diagnosis: The diagnosis of Pallister-Killian syndrome depends mainly on the demonstration of cytogenetic abnormalities because the clinical pictures can be confused with that of Fryns syndrome.

 AllRefer Health - Genetic Counseling and Prenatal Diagnosis (Prenatal Diagnosis)
Prenatal diagnosis involves testing fetal cells, amniotic fluid, or amniotic membranes to detect fetal abnormalities.
Genetic counseling and prenatal diagnosis provides parents with the knowledge to make intelligent, informed decisions regarding possible pregnancy and its outcome.
Based on genetic counseling, some parents (in the face of possibly lethal genetic disease) have forgone pregnancy and adopted children while others have opted for egg or sperm donation from an anonymous donor who is not likely to be a carrier of the specific disease.

 Prenatal Diagnosis
Special attention must be given to evaluating the morality of prenatal diagnostic techniques which enable the early detection of possible anomalies in the unborn child.
But since the possibilities of prenatal therapy are today still limited, it not infrequently happens that these techniques are used with a eugenic intention which accepts selective abortion in order to prevent the birth of children affected by various types of anomalies.
Diagnosis, not immoral in itself, must have a proper purpose and motive.

 UMHS Press Release: Utero Diagnosis
The study revealed that even with a prenatal diagnosis of HLHS, infants with one or more risk factors that are often not detectable before birth, such as low birth weight, had a significantly less chance for survival.
But the researchers note that in utero diagnosis has meant that many more pregnant women referred to specialty care centers for treatment before risk factors can be identified, which results in a higher risk group of patients.
By assessing the outcome of the patients, the researchers were able to identify four prominent risk factors associated with a decrease in survival rates: low birth weight/prematurity, obstructed pulmonary venous return, additional cardiovascular defects, and non-cardiovascular anomalies.
