What is molecular diagnostics? Molecular diagnostics, also called molecular pathology, involves taking DNA or RNA, the unique genetic code found in our cells, and analyzing the sequences for red flags that can pinpoint the potential emergence of a specific disease. The field has expanded rapidly in recent years.

In the near future, physicians will use molecular tests to diagnose and monitor diseases and predict genetic conditions as routinely as they use chemistry and hematology today. 4) The role of diagnostics will expand to include individual responses to customized drug therapies (eg, pharmacogenetics).

Molecular diagnostics are a battery of widely applied, powerful, and sensitive techniques used to identify biologic markers in a genome and proteome by detecting bacterial genes (with PCR-based techniques) and measuring expressed bacterial infection–specific proteins (with enzyme-linked immunosorbent assay [ELISA] and ...

(muh-LEH-kyoo-ler TES-ting) A laboratory method that uses a sample of tissue, blood, or other body fluid to check for certain genes, proteins, or other molecules that may be a sign of a disease or condition, such as cancer.

(muh-LEH-kyoo-ler dy-ug-NOH-sis) The process of identifying a disease by studying molecules, such as proteins, DNA, and RNA, in a tissue or fluid.

Molecular testing, or molecular diagnostics, refers to a group of tests that look at the genetic material in a specimen. It can detect genetic risk factors for certain diseases or provide evidence of infections in the body.

Molecular diagnostics, also called molecular pathology, involves taking DNA or RNA, the unique genetic code found in our cells, and analyzing the sequences for red flags that can pinpoint the potential emergence of a specific disease. The field has expanded rapidly in recent years.
