Summary
Nucleic acid testing (NAT) is crucial for managing chronic hepatitis B. This review highlights NAT's role in diagnosing, surveilling, and treating this global liver disease.
Area of Science:
- Hepatology
- Virology
- Molecular Diagnostics
Background:
- Chronic hepatitis B (CHB) poses a significant global health burden.
- CHB can lead to severe liver complications, necessitating advanced management strategies.
Purpose of the Study:
- To review the applications of nucleic acid testing (NAT) in CHB.
- To emphasize NAT's importance in the diagnosis and management of CHB.
Main Methods:
- Review of current literature on NAT techniques for hepatitis B virus (HBV).
- Discussion of quantitative PCR-based HBV DNA assays.
- Examination of HBV genotyping and mutation detection assays.
Main Results:
- NAT enables precise quantification of HBV DNA.
- NAT identifies HBV genotypes and antiviral resistance mutations.
- NAT detects key mutations like precore and core promoter variants.
Conclusions:
- NAT is indispensable for accurate CHB diagnosis and monitoring.
- NAT guides effective antiviral therapy selection and surveillance.
- Advanced NAT techniques improve CHB patient management outcomes.

Genomics
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

Pharmacogenomics: Identification of New Drug Targets
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
Modern Molecular Taxonomy
Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...
Sanger Sequencing
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
Pharmacogenetics and Pharmacogenomics: Overview
Pharmacogenetics and pharmacogenomics examine how genetic factors influence an individual's response to drugs. While pharmacogenetics focuses on the impact of specific genetic variants on drug effects, pharmacogenomics takes a broader approach, studying how genetic variation across populations contributes to differences in drug responses. These fields aim to explain why individuals may experience varying levels of efficacy or adverse reactions to the same medication.Variability in drug...
