Hepatitis B (HBV): PCR (Real-time PCR)

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 one of the most common and dangerous infectious diseases affecting the human liver. This viral infection is transmitted through blood and other types of contact and can lead to serious complications, including cirrhosis and liver cancer. For timely diagnosis and treatment of hepatitis B, it is important to use modern laboratory diagnostic methods, in particular, real-time polymerase chain reaction (Real-time PCR) and infection panel.

PCR (Polymerase Chain Reaction) is a molecular research method that allows to determine the presence and quantity of viral DNA or RNA in biological samples. In the case of hepatitis B, RNA-PCR is used, since the virus has an RNA genome. Real-time PCR is a modification of this method that allows to simultaneously amplify and measure the quantity of viral RNA in real time.

To diagnose hepatitis B by PCR, blood or serum from the patient is usually used. Viral RNA from the sample is extracted and converted into complementary DNA using special enzymes called thermostable DNA polymerases. This DNA is then amplified, allowing the presence and amount of viral RNA to be determined.

One of the main advantages of Real-time PCR is that it allows you to determine the amount of viral RNA in real time. This is especially important when monitoring the effectiveness of hepatitis B treatment, as it allows you to detect changes in the concentration of the virus in the patient's body in a timely manner. A decrease in the amount of virus during treatment indicates the success of the therapy.

In addition, the hepatitis infection panel includes other diagnostic methods, such as immunodiagnostics. This helps detect antibodies to the virus, which allows you to confirm the presence or past infection with hepatitis B. Studies may also include other biomarkers that indicate the condition of the liver and the degree of its damage.

A general analysis of the infectious panel helps doctors understand the extent of a patient's hepatitis B infection and choose the optimal treatment plan. If the infection is detected at an early stage, this makes it possible to prescribe antiviral therapy, which can relieve the patient from complications and prevent further spread of the infection.

In conclusion, hepatitis B (HBV) remains a serious threat to human health. The use of modern diagnostic methods, in particular real-time PCR and infectious panel, helps to detect and control the infection in a timely manner, which is an important stage in the fight against this disease and its complications. To maintain health, it is important to undergo regular examinations and consult a doctor about the possibility of vaccination against hepatitis B.
