Amniocentesis is a technique for withdrawing amniotic fluid from the uterine cavity using a needle, via a transabdominal approach and under continuous ultrasound guidance, in order to obtain a sample of fetal exfoliated cells, transudates, urine or secretions. It can be performed from 16 weeks of pregnancy onwards, with various chromosomal, biochemical, molecular and microbial studies being performed on the amniotic fluid sample. The most common reasons for the procedure are to enable prenatal…

Considering the negative effects of anxiety during the pregnancy, the patients should be well informed to reduce anxiety and consult with a relevant specialist for support if necessary.

Clinical Trial on the Usefulness of On-Site Evaluation of Canine Fetal Fluids by Reagent Test Strip in Puppies at Elective Caesarean Section

Differences between surviving and non-surviving puppies seem to suggest that the on-site analysis of fetal fluids’ composition by TS could represent a first-line diagnostic tool in the field of canine neonatology, allowing the quick recognition of puppies needing assistance as a complementary tool for clinical evaluation.

Chromosomal abnormalities in a decade of prenatal testing at the Department of Obstetrics and Pathology of Pregnancy Medical University of Lublin

It is a proof that modern, non-invasive procedures like the first-trimester ultrasound scan and biochemical tests should be made available to every pregnant woman and not only to mothers’ aged >35 years or those with a poor obstetrics history.



Technique modifications for reducing the risks from amniocentesis or chorionic villus sampling.

The quality of evidence summarised in this review is not of sufficient quality to change current clinical practice, and the operators should continue to use methods and technique modifications with which they are most familiar with.

Chronic Viral Infections and Invasive Procedures: Risk of Vertical Transmission and Current Recommendations

Amniocentesis seems to be safe when performed under highly active antiretroviral treatment, with a low viral load and when avoiding placental passage, but serological status should be assessed in all cases and parents should be aware of the existing evidence for transmission risk.
