Broadly speaking, any qualitative and quantitative analysis of an organism's DNA sequence and its products (such as RNA and proteins) using molecular biology techniques is called molecular diagnosis.

Molecular diagnosis of DNA and RNA is usually called genetic diagnosis

Strong specificity

high sensitivity

Enables quick and early judgment

Strong applicability and wide diagnostic range

Blood, tissue blocks, amniotic fluid and villi, semen, hair, saliva, etc.

Nucleic acid molecular hybridization technology (basic)

PCR technology (specific, fast)

DNA sequence analysis (most direct)

Gene chip technology (large scale)

Genetic disease diagnosis and risk prediction

Predictive diagnosis of common polygenic diseases

Infectious Disease Pathogen Detection

Disease efficacy evaluation and medication guidance

DNA fingerprinting
