DNA Microarray

Also known as: DNA microarray, DNA microarray-based diagnostics, microarray-based gene expression testing, gene expression profiling.

What is a DNA microarray?

A DNA microarray is a blood that looks for missing or extra pieces of an individual DNA. It can be useful for identifying genetic causes of disease and developmental delays.

What happens during the procedure?

A routine blood draw is required in order to begin the microarray-based testing. The blood sample is then taken to a laboratory for testing and analysis.

Is any special preparation needed?

No special preparation is needed for the test.

What are the risk factors?

Infection, bleeding and damage to surrounding organs and tissues are potential risks of any blood draw.
