i dont consider the nuchal scan to be a gimmick, i had the nuchal scan and the blood test, they looked at the heart, kidneys,stomach,umbilical cord, the brain, checked the baby had all its fingers and toes and also looked for certain hernias and checked the baby didnt have any markers of major chormosone abnormalities, they were also able to rule out some major heart defects. obviously it doesnt guarantee the baby a clean bill of health, but it does pick up 85-90% with a chromosone problem and gives the chance of an earlier diagnosis, rather than waiting for the triple test at 16wks which isnt as reliable.
i consider it to be money well spent and this is the third pregnancy where i have paid for it.
depending on where you live the test is offered for free, if i lived in the next county i would get it for free, it just so happens that i dont under my local health authority, although they ARE planning to give it to all in the next 6mths.
i have the form in my notes, i may look and see what it actually says!
