Test Overview

Test Methodology

Relative-quantitative PCR

Test Usage

This relative quantitative polymerase chain reaction (rqPCR) assay is used to confirm a patient’s abnormal CMA result(s) and to determine the origins of inheritance of an aberration by testing parental samples. This assay is used to confirm aberration(s) that are too small or that cannot be confirmed by FISH for the patient’s and/or the parental samples. In addition, this rqPCR assay can also be used for a symptomatic sibling(s) to screen for a known familial copy number aberration previously detected by CMA testing at the MMGL-Molecular Genetics Laboratory. There is a separate charge for parental and sibling rqPCR testing.

Reference Range

Interpretive report provided.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
