EFTS & STS Screen Positive
Enhanced First Trimester Screening or Second Trimester Screening can give you results that are either "screen negative" or "screen positive". If your test result is "screen positive", you might have questions about what this means and what the next steps are.
What the result means
A "screen positive" result means there that there is a higher chance for the baby to have trisomy 21 (Down syndrome) or trisomy 18 (Edward syndrome). It does not mean that the baby definitely has one of these chromosome differences.
Most of the time when there is a "screen positive" result, the baby does not actually have trisomy 21 or trisomy 18. This means that the result is usually a false positive.
