Clinical Information
Test purpose: Help
Diagnosis
Target population: Help
Fetus that had previous chromosome or microarray analysis done and need a confirmation of previous result or abbreviated chromosome analysis done on amniotic fluid sample (e.g. previous chromosome or microarray analysis done on different tissue type, e.g. chorionic villi).
Variant Interpretation:
Are family members with defined clinical status recruited to assess significance of VUS without charge? Help
No.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
No.
