Combination test: blood tests, skin fold measurement, rashes, and other charges. The combined test can be carried out at any pregnant woman, if it is not yet fourteen weeks pregnant. On the basis of this test can detect chromosomal abnormalities, including Down's syndrome. The rash usually follows within a week. What are the costs fen fee for this?
Every pregnant woman can choose the combination test, it does not matter what age the woman. For the woman from thirty years, the combination test more certainty about the child, because the chance of an abnormality in the child grows.
The combination test consists of two parts. First, it performs a blood test when the woman between 9 and 14 weeks pregnant. The blood which is going to decreased to a laboratory and analyzed there. The blood is analyzed for the pregnancy hormones Free-Beta-hCG and PAPP-A. In pregnant women who are carrying a child with one of the three syndromes, these blood levels are different, although the difference is not great.
If a second nuchal translucency measurement is performed in the unborn child. The neck is some fluid in children with Down's syndrome include the nuchal fold thicker. The thicker this layer, the more the chance of a child with Down's syndrome. The nuchal translucency measurement is performed by means of an echo. Woman feels nothing of this. The nuchal translucency measurement is performed at a gestational age of 11 to 14 weeks. The order of both can vary, but must both be completed before 14 weeks' gestation.
On the basis of the blood test, the nuchal translucency measurement, the age of the woman and the gestational age, there may be a probability calculation to be made. This calculation, moreover, does not guarantee: with a low probability the child may just as well have one of the syndromes. When there is an increased risk, the child can be equally good health. The probability therefore gives an indication.
A woman of 38 years of age or older is on the basis of all of her age to this increased risk. Precisely for these women is recommended that a combined test. This is recommended from the age of 37 years, but they want to reduce this to 35 years. The probability that a child with Down's syndrome detection is 85 percent. However, in 15 percent of the cases, the syndrome is not detected when there is still the question.
