Do I need to see a Genetic Counselor?

A genetic counselor can help you understand the reason for genetic testing and explain the test results to you and your family. Genetic counselors are trained professional who provide you information pertaining to your health condition, appropriate referrals, test selections for you and other family members and play a supportive role.

What sample is required for CMA testing and how is the sample collected?

What is a Chromosomal Microarray Analysis (CMA) test?

Chromosomal Microarray Analysis (CMA) is also known as array comparative genomic hybridization (CGH) or SNP microarray or genomic array. This is a new genetic technology that can find the missing or extra DNA or genes. This technology scans the entire genome and provides information on thousands of genes in a single test.
