Integrated versus sequential screening?

My ob/gyn offers both, but I'm not entirely sure what the differences are between the two.

Anyone know?

Re: Integrated versus sequential screening?

Oh lordy Im not so good at explaining this but I'll try....

In sequential screening they essentially do the ultrascreen at the usual time (draw the blood and do the ultrasound) if those results are abnormal you will be notified...if they are normal then you will have another blood test at 16ish weeks (consider it the AFP) and those results will be combined with your first blood test and then you will get your risk of having a baby with Down Syndrome etc...

In Integrated testing the procedure is the same....but the protocol is different. You dont get any results until after the second blood test.

Both have the same false positive/false negative rates and are equally able to diagnose Down Syndrome etc...

Does this make sense? Feel free to FM me if you have any more questions.

Thanks!!

SO what are the benefits of doing one as opposed to another? If i understand correctly, the only difference is that, with the integrated, they don't give you your first results immediately after.

If they both test the same thing and have the same statistics, why do one as opposed to the other?
