Determining a cutoff for fetal lung maturity with lamellar body count testing.

29 Apr 2009 OBJECTIVE: A lamellar body count (LBC) >or= 50,000/microl is suggested to document fetal lung maturity (FLM). We sought to determine the LBC threshold for FLM with the Cell-dyn 4000 hematology analyser. METHODS: We queried our database for patients ... Read more...

Techniques for chorionic villus sampling and amniocentesis: a survey of practice in specialist UK centres.

29 Sep 2008 OBJECTIVES: Guidelines exist for amniocentesis and chorionic villous sampling (CVS) practice, but there is no consensus regarding individual techniques. Our survey sought to review current practice within specialist centres in the United Kingdom. ... Read more...

ACOG Practice Bulletin No. 88, December 2007. Invasive prenatal testing for aneuploidy.

29 Nov 2007 Prenatal diagnosis of fetal chromosomal abnormalities is the most common indication for invasive prenatal testing. The prevalence of chromosomal abnormalities in clinically recognized early pregnancy loss is greater than 50%(1). Fetuses with ... Read more...
