The dna of the hepatitis b virus (hbv-dna) is the basis for the core substance of the hepatitis b virus and its reproduction. Under the “instruction” from the genetic genes carried with the virus's dna, hbv dna replicates the new virus's shell and dna core, respectively, and is then reassembled into a large number of new viruses, releasing them and continuing to infect other liver cells。
Hepatitis b virus dna is a more direct, specific and sensitive indicator of hbv infection, hbv-dna positive, suggesting hbv replication and transmission. The higher the hbv-dna, the more the virus is replicated and contagious. The expert at the hospital attached to the henan provincial institute of medical sciences noted that the continued reproduction of hepatitis b virus was the underlying cause of hepatitis b disease and that the underlying purpose of hepatitis b treatment was to inhibit the reproduction of the virus。
Hepatitis b
The test of hbv dna can determine the programme of antiviral treatment, specifically the significance of hbv dna testing is:
1 chronic hepatitis b diagnosis and classification。
2. Determines whether treatment is needed and when it begins。
3 surveillance of the condition in the course of antiretroviral treatment。
The progress of the post-treatment situation is judged and whether clinical treatment targets have been met。
The high number of dna tests for hepatitis b generally represents a rapid and contagious development, requiring active antiretroviral treatment. Since hbv-dna is a sensitive indicator of the number of hepatitis b viruses, hepatitis b treatment is an important and concerned indicator of the number of hepatitis b viruses in the body. Thus, when there is a high number of hb dna tests, the use of treatments for the rapid and effective elimination of hbv can lead to a relatively large reduction in the development of the disease and to a relatively short period of improvement in the patient's symptoms, leading to rapid recovery of hb。
Internationally recommended hbv dna testing normal
In the past, antiviral treatment of hepatitis b showed that hbv dna values for hepatitis b virus e antipositive (the great three-positive) required up to 10 copies (2000 u/ml), and hbv dna values for hepatitis b virus e antineagnosis (the little three-positive) required up to 10 copies/ml (2000 u/ml), but the four copies below 10 could not be considered to be unproblematic, and more recent international studies indicated that the range of dna levels of viruses associated with progress in liver disease was unclear: even if the hbv dna levels were still below 2000 u/ml, it was likely that the hepatitis b virus would be further developed, so that the hbv dna values should be as low as possible, and the current recommended normal values for hbv dna testing should be:
Why is hep b testing virus dna
The hepatitis b virus gene is a substance containing genetic information and is the basis for the reproduction of the hepatitis b virus. As a result, the prevalence of hbv dna in the patient was detected and the reproduction of the hepatitis b virus was indirectly detected. Hepatian doctors now perform hbv dna quantification tests for patients, which are needed for clinical medicine and for developing treatment programmes. If the amount of hepatitis b virus (i. E. Hbv dna quantification) is found in treatment is decreasing, the effectiveness of antiretroviral treatment is demonstrated. On the other hand, if the increase in the volume of hepatitis b virus is detected in treatment, it means that anti-virus treatment is ineffective and there is a need to re-select drugs and adjust treatment options。
To provide more accurate, specialized scientific testing and diagnostic data for treatment needs and to facilitate better access to information on the disease, patients and the general public, the hospital attached to the henan provincial institute of medical sciences has a web-based appointment platform, which allows people across the province to make online appointments。
