Objectives To validate the use of Real Time PCR, a widely used technique that can detect
very low levels of Y chromosomal sequence, and to assess the use of a highly sensitive …

The present study was undertaken to evaluate a nested polymerase chain reaction (PCR)
for detection of Y chromosome‐specific fetal DNA in maternal plasma and urine of pregnant …

OBJECTIVE: Clinical indications for fetal sex determination include risk of X-linked
disorders, a family history of conditions associated with ambiguous development of the …

Objective Aiming to develop more reliable methods for determination of fetal gender from
maternal plasma we compared three different systems of polymerase chain reaction (PCR) …

Background We determined fetal sex in pregnancies referred for invasive prenatal diagnosis
procedures by analysis of DNA in maternal plasma. Methods Twelve pregnancies at risk of X …

Fetal male DNA can be identified in maternal blood by polymerase chain reaction (PCR)
amplification of Y-specific sequences. This technology has not reached a satisfactory …

Background: In order to provide a reliable non-invasive method for fetal sex determination in
a routine setting, we evaluated the possibility of identifying the fetal Y chromosome-specific …

Non-invasive prenatal diagnosis is now a clinical reality, using both early ultrasound and
molecular DNA methods. Technical advances in the sensitivity of the polymerase chain …

INTRODUCTION: Non-invasive methods using maternal plasma and serum for molecular
genetic diagnosis become an important field of interest in prenatal genetic diagnosis. Free …

We have developed a real‐time PCR assay for early fetal gender diagnostics based on the
analysis of the Y chromosome–specific multicopy DAZ sequence in the circulating DNA from …
