Combined test- a combination of NT scan and the blood test is a Screening test. Meaning it will tell you if the baby is at a high or a low risk for the problem however it won't tell you if baby has a problem or not. The people who are at high risk are offered further confirmatory test like CVS or Amniocentesis, people who are intermediate risk may opt for a more accurate blood test called NIPS or NIPT. People who are low risk usually opt not to go for any further testing.
Next Steps
contact a fetal medicine doctor( who specialises in this testing) as accuracy of the results is crucial which can be achieved by experts.
Health Tips
