Indication

This is a clinical test intended for Help: Diagnosis

Clinical summary

Help

A disorder that results from a chromosomal abnormality. [from NCI]

Conditions tested

Target population

Help

Individuals who had previous chromosome or microarray analysis done and need a confirmation of previous result or abbreviated chromosome analysis done on tissue sample such as a skin biopsy sample (e.g. previous chromosome or microarray analysis done on different tissue type, e.g. blood sample). Products of conception tissue from pregnancy that previously had a chromosome or microarray analysis done (e.g. chorionic villus sampling or amniocentesis) and needs confirmatory chromosome analysis done.
