About this study
Information on pregnant women undergoing non-invasive prenatal testing (NIPT) at one of the Obstetrix Medical Groups Outpatient Centers between January 2012 and June 2014 will be retrospectively gathered and an analysis of the impact and prevalence of NIPT. This will be compared to a control group of pregnant women in those same practices undergoing prenatal testing during the months of January 2010-July 2010.
Read the detailed description
Information regarding the frequency of non-invasive testing (NIPT), the impact of screening on the need for and frequency of invasive testing, and the indications for testing are important for the clinicians in this country to not only understand the impact that this testing has had but also to plan for allocation of personnel and resources in their prenatal testing units, as well as many other more subtle changes including describing changes to referring clinicians and patients and projecting financial impacts. Information on pregnant women undergoing NIPT at one of the Obstetrix Medical Groups Outpatient Centers between January 2012 and June 2014 will be retrospectively gathered and compared to a control group of pregnant women in those same practices undergoing invasive prenatal diagnostic testing for fetal karyotype (IDTFK) during the months of January 2010-July 2010. An analysis of the impact of NIPT will be done.

| IDTFK Group Post NIPT - (January 2012-June 2014) | Pregnant women who present to participating centers between January 2012-June 2014, after the release of non-invasive prenatal testing (NIPT), who are undergoing invasive prenatal diagnostic testing for fetal karyotype (IDTFK).

| IDTFK Group pre-NIPT (January 2010-July 2010) | A control group of pregnant women, prior to the release of non-invasive prenatal testing (NIPT), who present to participating centers between January 2010-June 2010 and are undergoing invasive prenatal diagnostic testing for fetal karyotype (IDTFK). |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Patient Undergoing IDTFK Before (Control) and After (Test) NIPT Testing Came to Market
Total Number of patient undergoing invasive diagnostic testing for fetal karyotype (IDTFK) before (control group = Jan - July 2010) and after (test group=Jan 2012-June 2014) NIPT testing came to market
Measured: 4 years
Secondary outcomes (1)
Frequency of Positive Tests for Abnormal Karyotype Before and After the Adoption of NIPT Testing.
Will determine if frequency of positive tests for abnormal karyotypes between the control period and the study period where different.
Measured: 4 years
