Technology of auxiliary clinical diagnosis

Some fertilized eggs (germplasms) or mothers are affected by environment or heredity, resulting in harmful changes in the next generation genome, resulting in (physical) diseases. In order to solve and prevent them, it needs to be confirmed through laboratory gene diagnosis and gene analysis. Also known as DNA diagnosis or molecular diagnosis. With the current understanding of human genome and molecular genetic data, we can check the level of molecular structure and expression, and make the diagnosis of common genetic diseases or familial genetic diseases.

Advantages of genetic diagnosis

For direct etiological diagnosis

Compared with conventional diagnosis, gene diagnosis completely breaks the conventional diagnosis method, no longer infers the occurrence and mechanism of disease based on the phenotype of the disease, but pays more attention to individual gene status, realizes the detection of etiology from the gene level, so it has strong pertinence.

High specificity and sensitivity

At present, people have established a variety of biological samples such as blood, semen, urine, epithelial cells, saliva, bone for gene diagnosis. Due to the development of gene amplification technology in vitro, only a small amount of samples need to be analyzed, and the target gene only needs PG level.

It has strong adaptability and wide diagnosis range

The test object can be a specific gene, a specific genome, an endogenous gene or an exogenous gene. It can not only judge the disease of patients, but also predict the susceptibility of patients with normal phenotype but carrying a specific disease gene or specific disease.

No tissue and developmental specificity

Whether the target gene is activated or not is not tissue-specific or developmental specific.

It can detect growing pathogens or latent pathogens

In the genetic diagnosis of infectious diseases, growing pathogens or latent pathogens can be detected.

Trecare Case

Genetic diagnosis

The premise of gene diagnosis

Whether the detected gene has been located on chromosome;
Whether the structure of the tested gene is clear;
The known mutation types of the tested genes;
Whether there are closely linked polymorphic DNA markers in the tested genes;
Function of tested genes and their role in the occurrence and development of diseases

Samples for genetic diagnosis

It can be any nucleated cell, including:
Peripheral blood leukocytes and oral mucosal cells
Biopsy specimens, paraffin embedded tissue blocks
Precipitated cells (saliva, sputum, urine)
Amniotic fluid cells, villous cells and fetal cells entering maternal circulation
(using PCR, the sample can be miniaturized to one cell)

The content of gene diagnosis

Detection of gene mutation
Gene linkage analysis
Analysis of gene expression

Service Flow

Service process

Appointment of gene Consultant

In the first consultation, the genetic counselor will determine the detection method through the other party's family history, personal living habits, physical condition, working environment and other factors.
