Test developed by laboratory (no manufacturer test name)

Test procedure

Help

FISH confirmation/visualization of the majority of copy number abnormalities. If submitting a specimen that cannot be cultured, such as frozen tissue or extracted DNA, a secondary specimen may be recommended for follow-up by FISH visualization (at no extra charge). Molecular studies may be recommended depending on specific test results.
