What is Molecular Diagnosis?

Genes carry all the mysteries of life, and molecular diagnosis is the golden key to unlock the mysteries.

1. Molecular diagnosis

Molecular diagnosis mainly refers to the use of molecular biology methods to detect changes in the structure or expression level of genetic material in patients to make a diagnosis.

As one of the important fields of in vitro diagnosis, molecular diagnosis can realize the genome analysis of individuals and provide personalized diagnosis. Because it far exceeds other diagnostic methods in terms of accuracy and information density, it has become the current in vitro diagnosis industry. The industry segment with the highest technical requirements and the most growth potential in China.

In 1953, Watson and Crick proposed the double helix structure of DNA. Since then, the "mystery of life" has been opened, people have begun to clearly understand the composition and transmission of genetic information, and in vitro diagnosis has ushered in new development. After PCR technology, biochip technology, and DNA sequencing technology, molecular diagnosis has quickly become one of the most effective ways to diagnose human diseases.

2. Molecular diagnostic technology

At present, molecular diagnosis covers the following technology platforms: polymerase chain reaction (PCR), fluorescence in situ hybridization (FISH), gene chip and gene sequencing (NGS).

Among them, PCR technology is mainly to amplify and detect extremely low concentrations of DNA; FISH is mainly based on probes and fluorescein to detect specific gene fragments; and gene chips can detect multiple gene targets at one time; gene sequencing is in detecting gene sequences in longer dimensions.

At present, PCR technology, FISH technology, and gene chip are relatively easy to use in clinical applications, so the detection cost is low. Among them, PCR technology has the largest market share and the most mature application. NGS technology is more complex in clinical application and requires higher requirements, so the detection cost is higher.
