Next-Generation Sequencing (NGS) panels allow investigation of multiple genes simultaneously in situations where there is phenotypic overlap across disorders.
A DNA microarray is a collection of microscopic DNA spots attached to a solid surface used to measure the expression levels of large numbers of genes simultaneously.
RT-PCR is a PCR test that is designed to detect and measure RNA. Although initial PCR tests amplified DNA, many viruses and other biological components utilize RNA as their genetic material.
