Question: I want to know about nt scan and double marker test and why it should be done and what happens if the risk ratio is high?
Answer: Nt scan along with double marker test are done to screen for any chromsomal abnormalities in your baby such as Down's syndrome etc. Based on your maternal age, double marker test defines a risk ratio. If you are below the cut off, it is low risk and so on.However, blood test alone can not determine the actual risks. Nt scan measures the amount of fluid at the back of your baby's head which is generally high for down syndrome babies. Hence both of them combined gives you the calculated risk. Do not worry, most of the time it turns out normal and hence it is just a screening test not a diagnosis test. Take care.
