Worldwide, chronic hepatitis B and C infections remain a significant public health challenge, causing millions of cases of liver disease globally.
The objective of this article is to highlight the need for testing and monitoring hepatitis B and C virus infections using Real-Time PCR, as well as to analyze the implementation of strategies for the eradication of hepatitis in accordance with WHO targets for 2030.
This narrative review highlights the necessity, performance, advantages, limitations, and challenges of implementing Real-Time PCR testing in clinical practice and public health policies for hepatitis B and C.
The results show that Real-Time PCR has superior sensitivity and specificity in the early detection of active infection and monitoring of viral load, facilitating optimal therapeutic management. Serological testing retains its essential role in initial screening, identifying exposure to viruses. Vulnerable groups, including hemodialysis patients, people who inject drugs, HIV-positive patients, healthcare workers, and marginalized populations, have increased prevalence and require prioritization in testing. The main limitations reported include unequal access to PCR technology and potential technical errors. Proposed strategies for improving testing include expanding access to molecular techniques, awareness campaigns, standardization of protocols, and international collaborations to support screening and treatment.
The conclusions emphasize that integrating serological testing with Real-Time PCR and focusing on vulnerable groups are crucial for achieving the objectives.

Controls in Real-Time Polymerase Chain Reaction Based Techniques
From its discovery in the 1980s, Polymerase chain reaction was further developed and is nowadays used as the foundation for the various PCR-based techniques used in molecular diagnosis across different species, and numerous types of samples. Real-Time PCR enables the user to monitor the amplification of a deoxyribonucleic acid (DNA) or complementary DNA (cDNA) target during the PCR run, in real-time, and not at the end, as it is the case in conventional PCR. The most frequent types of applications include gene expression analysis, gene silencing, variant analysis, and fusion temperature analysis. Given its vast field of application, a key question remains, and it is related to the controls (negative controls, positive controls, internal exogenous and endogenous controls) and their purpose in a Real-Time PCR experiment. In this paper, we set out to find how and when to use them, and which type of controls are suitable for certain experiment types, since the use of appropriate controls during Real-Time PCR experiments will reduce the effects of variables aside from the independent variable within the sample, therefore yielding accurate results, be it in research or diagnostic purposes.
Screening the Presence of Amflora Transgenic Potato in Food or Feed Products
Objective. Amflora potato, event EH92-527-1 was genetically modified to produce only the amylopectin component from starch composition. The presence of the transgenic potato in the food on Romanian market should be verified although the Amflora potato uses for industrial purposes and animal feed. The aim of this study was to detect the presence of the Amflora potato in the food or feed products.
Methods. For this purpose, five samples of potato tubers and four samples of chips were analyzed. DNA isolation was performed with E.Z.N.A. ® MicroElute Genomic DNA kit (Omega Bio-Tek, USA). For identification a potential presence of the recombinant DNA in the food samples it was used GMOIdent RT Event EH92-527-1 Potato kit (Eurofins GeneScan, Germany), that is a real-time PCR kit for qualitative event-specific detection of AmfloraTM EH92-527-1 potato.
Results. Amflora transgenic potato was not detected in any of analyzed samples.
Conclusions. The results of real-time PCR method confirm the absence of Amflora event EH92-527-1 in all potato tubers and chips analyzed samples.
