Its origins are in the early days of ultrasound where a more detailed ultrasound examination was performed to explain the abnormal results of a screening blood test, called the Triple Test or MSAFP Blood Test.

Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening.
Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis. This means that combined first trimester screening simply tells us if your risk is low or high. For example, it tells us whether your baby has a low risk of having trisomy 13, 18 or 21, or whether your baby has a high risk of having trisomy 13, 18 or This test gives us an indication of whether we should worry about your baby based on these results.
This means that combined first trimester screening will not give us a definitive answer.

References “The technology of prenatal diagnosis is usually presented to us as a solution, but it brings with it problems of its own If you’ve already read it, you may want to skip ahead. All pregnant women in our technology-happy modern society face confusing choices about prenatal testing, its advantages and disadvantages, and its appropriateness for them. Large pregnant women face even more confusion, since prenatal testing can be slightly harder in this population, and the results can be more confusing.
However, since they may be at a somewhat increased risk for problems like neural tube defects, they also face greater pressure than others to have these prenatal tests, even though the tests are often difficult to interpret. It is further designed to address the special concerns that large women might have in taking these tests their fears, any special equipment or techniques that might be helpful, the controversies over interpretation of results, whether large women have a higher rate of so-called ‘false-positives’ on certain tests and why, etc.
