Cobine Screening: Nuchal transluncency and first trimester screening

Nuchal Transluncy test as described in the previous post, can be combined with doing a blood test.
The blood test measures 2 items:

• Free beta HCG
• PMPPA (pregnanct associated plasma protein A)

Like the Nuchal translucency test, this is done between 11 week 3 days to 13 weeks 6 days. The blood test results barely takes a few hours for the results to be available.
The detection rate of down syndrome is improved with this test at up to 90%
