This test compares the patient’s sample to a normal control sample to find very small missing or extra chromosome pieces that cannot be seen under a microscope.

Chromosomal microarray analysis (CMA) identifies chromosomal deletions and duplications and helps healthcare providers to determine the genetic etiology of their patient's conditions. These missing or …

Nov 10, 2025 · A microarray is a biotechnology tool that allows scientists to simultaneously measure the activity or presence of thousands of genes or proteins on a single, small chip.

Aug 15, 2020 · A DNA microarray is a tool used to determine whether the DNA from a particular individual contains a mutation in genes.

Microarrays are versatile tools that analyze thousands of genes or genetic variations at once. They are used to study gene expressions, detect mutations, and identify biomarkers in research.

Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome. Each DNA spot contains picomoles (10 …

Aug 20, 2025 · A microarray test is a genetic test that examines a person’s DNA to detect missing or duplicated segments. This laboratory technique provides a comprehensive overview of genetic …

A microarray is a laboratory technique used in the study and analysis of biological molecules, particularly DNA and proteins, in which a probe of interest is affixed in a grid pattern to the surface of a small chip.

A chromosomal microarray analysis, also called microarray or array, is a type of genetic test that looks for missing or extra portions of a chromosome. We call these “deletions” or “duplications.” In this …

Microarray analysis is defined as a technique that enables the simultaneous detection of expression levels of numerous genes through molecular hybridization between probes and target nucleotide …
