I would always suggest getting the Downs test done, even if you didn't plan on having an abortion. If it comes back negative...great...if it comes back positive, you have time to prepare for your special baby. For most people it's a shock but having a Downs baby isn't a terrible thing...
Both my brother and sister have Downs (Adams on the left, Lucy is on the right). They both speak fluent Spanish and English, despite their problems (and there aren't many "normal" people that can say that) Lucy also translates for her deaf friends as she can also sign. Adam swims for Spain for the Special olympics and my sister is quite the proficient ballet/tap dancer, winning many trophies, medals and cups.
There are many services on offer for people with special needs babies, and the from when you find out you are expecting a baby like that you will have time to prepare for the arrival, accessing these services.
Downs people aren't as difficult to look after as people think as long as you treat them as normally as possible and force them to do as much as they can for themselves. They are quite intelligent and will play on their disabilities, if they think they can get out of doing the washing up or tidying their rooms, like everyone

. They also encorage their siblings to be a lot less demanding and selfish, as well as being a lot more mature. For me, as a sibling, it was other peoples attitudes towards them that upset me the most, not actually having them. I never missed out on love, but I missed out on friends because most people are too narrow minded.
I am going to have the blood test done, but not to be on the look out for Downs but a more serious condition called Edwards Syndrome (or Trisomy 18 ) the most common form of Trisomy after Downs. Almost every baby will die before their first birthday, if they are ever born. My sister was born with this condition, and it terrifies me that I should ever have a child with the same condition. I know I carry a genetic marker for the condition as I was tested when I had Tia. I don't think I could watch another baby die from that condition and in that case I would have an abortion.
