Recommendations:

Venous blood is donated for PCR testing and PCR genetics.
Blood is collected on an empty stomach, after an overnight fast, or 8-12 hours after eating.
On the day of blood donation, it is allowed to drink a small amount of pure water.
6-12 hours before the study, stressful situations should be avoided and physical activity should be limited.
Avoid fatty foods, alcohol, and smoking.
If possible, medication should be avoided.
For infants – allow as long a gap between feedings as possible before handing over.

Hepatitis B (HBV) is a serious viral disease that attacks the liver and can lead to various complications, including cirrhosis and liver cancer. This virus is one of the most common viral infections in the world and is a serious medical problem. However, thanks to new diagnostic methods, such as real-time polymerase chain reaction (Real-time PCR), it is possible to more accurately determine the presence of HBV and take timely measures for control and treatment.

PCR (Polymerase Chain Reaction) is a highly sensitive and highly specific methodology for the detection and quantification of nucleic acids in biological samples. In the case of HBV, PCR can be used to detect viral DNA in a patient's blood plasma. Real-time PCR analysis, or Real-time PCR, is an improved version of PCR that provides the ability to determine the presence of the virus with high accuracy and speed.

One of the main advantages of Real-time PCR is that it allows to determine the amount of viral DNA in a sample. This information is extremely important for assessing the extent of infection, monitoring treatment and predicting the possible outcome of the disease. With this methodology, it is also possible to determine the degree of viral replication, which helps to take into account the effectiveness of treatment.

Real-time PCR allows for analysis not only in quantitative but also in qualitative terms. This means that the answer can be given quickly, and the results of the study can be available in the hospital or laboratory in the shortest possible time.

Real-time PCR also allows for the determination of the genotype of the HBV virus. This is important because there are different genotypes of the virus, and some may be more aggressive and difficult to treat than others. Knowing the genotype can be useful in choosing the optimal treatment and predicting the prognosis of the disease.

In general, real-time PCR is a powerful tool for diagnosing and monitoring hepatitis B. It allows not only to detect the presence of the virus, but also to determine its quantity, genotype, and monitor the effectiveness of treatment. This methodology has become an integral part of modern medicine and helps doctors to individually approach each patient with hepatitis B to provide the best possible care and treatment results.
