Microarray Analysis

Microarray Analysis

High Resolution microarray panels which screens for submicroscopic chromosomal changes in DNA with whole genome coverage.

CMA looks for imbalances in the amount of chromosomal material in a DNA sample by comparing it with a reference database. This information helps determine type of disorder in the sample.

What CMA delivers ?

Information about Submicroscopic Chromosomal Genetic Changes in DNA, which might not be picked up by routine techniques such as FISH and Karyotyping.

LEARN MORE

• Whole Genome information through ACMG and ACOG recommended First Line Genetic Tests for Postnatal and prenatal screening respectively.

• Greater Diagnostic yield (20-25%) over traditional chromosomal analysis with Karyotyping / FISH (3-5%)

• Fast TAT to report with whole genome information in 8-10 working days.
