1. Hepatitis B Surface Antigen: Surface antigen is what used to be called "AusAg". "It is short for "Australian antigen" because it was first found in Australia, so it is called "Australian antigen". Hepatitis B virus has a very simple structure, but it also has a shell. This shell is a protein called "surface antigen". Its presence signals the presence of the hepatitis B virus. Therefore, if the test is positive for "surface antigen", it means that the body is infected with hepatitis B virus.
Anti-HBs
2. Hepatitis B Surface Antibody: Hepatitis B virus invades the human body, and the body produces a substance to resist it. This substance is also a protein, which is called "antibody". Antibodies have the ability to protect the human body. When the body produces "surface antibodies", it means that the body is resistant to the hepatitis B virus. Nowadays, many people have been vaccinated against hepatitis B, so their bodies will also produce "surface antibodies", and the test for "surface antibodies" will also be positive. At this time, you hope that the "surface antibody" better be positive, which is a sign that you injected the hepatitis B vaccine, vaccination success, will not be infected with "hepatitis B" again.
HBeAg
3. Hepatitis B e antigen: e antigen is a sign of the replication of the hepatitis B virus. It can determine the degree of infectiousness. If the test is positive for e antigen, it means that the hepatitis B virus is actively replicating in the human body, and the amount of poison in the blood is large and highly infectious. Therefore, e antigen positive is definitely not a good thing.
Anti-HBe
4. Hepatitis B e-antibody: e-antibody is found during the examination, which indicates that hepatitis B is relatively better, and brings good news to the patient. Because it is positive, marking the replication of hepatitis B virus has changed from active to relatively static, the amount of poison in the blood is reduced, and the infectiousness is relatively reduced.
HBcAb
5, Hepatitis B core antibody: for those who have been infected or are being infected will appear as a sign. The core antibody IGM is a sign of recent infection or viral replication, and the core antibody IgG is produced after infection, which is of some significance in assisting the two-half test. The price of two-to-half test, i.e. hepatitis B five, is generally between 30-50 dollars, which is mainly affected by the medical level of hospitals, laboratory equipment, regional differences and other factors, and will show different prices. For the two half of the examination cost is still relatively cheap, are within the scope of people can afford.
Hepatitis B two-half examination is a general physical examination of the mandatory items, many people before going to the physical examination will ask the question of the cost of checking hepatitis B two-half, the cost of checking hepatitis B two-half is usually not expensive, but because of the size of the hospital is not the same, the city is not the same, hepatitis B two-half the cost of the cost of the difference, but usually the difference is not large, the examination of the patient can be in the local hospitals for inquiry.
As for the cost of the test, the hepatitis B test is a preliminary test to determine whether you are infected with hepatitis B or to estimate the level of viral replication, and the test is not very informative in assessing the severity of the disease. Liver function is an important test to measure whether there is necrosis of liver cells and inflammation, of which transaminases are the most important, and treatment needs to take liver function as an important reference index. Hepatitis B virus DNA test is to determine how to treat the reference basis, but also has a certain reference significance to the infectiousness, usually the higher the DNA, the more infectious, also requires with the liver function check. The cost of the test depends on the situation.
Hepatitis B two-half is the most commonly used serum marker for detection of hepatitis B virus infection in domestic hospitals, what is the hepatitis B five-point test? It has five main indicators, which are hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs), hepatitis B e antigen (HBeAg) and hepatitis B e antibody (anti-HBe), and hepatitis B core antibody (anti-HBc). Hepatitis B two-half tests, also known as Hepatitis B five, can determine whether you are infected with Hepatitis B and the specifics of your infection.
The cost of the hepatitis B test: the domestic hepatitis B test (hepatitis B two-half test), which is a qualitative test that shows only negative and positive values, is usually around 35-70 yuan, of which the core antigen test is usually around 30 yuan; the imported hepatitis B test, which is a quantitative test that shows the values of the hepatitis B two-half test, is comparatively more expensive, and is usually around 150 yuan. The cost is relatively higher, usually around 150 yuan. The cost is relatively higher, usually around 150 RMB. The physical examination can be qualitative only, and quantitative test can be used for treatment in order to evaluate the efficacy of treatment. Hepatitis B two-half test common results such as
(1) + - - - - the first positive, the remaining four negative. This kind of hepatitis B two-half test result indicates a late latent stage of acute hepatitis B virus infection;
(2) - - - - + the fifth item is positive, and the remaining four items are negative. It indicates a latent carrier of the hepatitis B virus or in the window period of infection, and also indicates a previous infection with the hepatitis B virus;
(3) + - + - The first and third items are positive, and the remaining three items are negative. This type of hepatitis B half-pair test result indicates the early stages of acute hepatitis B;
(4) + - - - + The first and fifth items are positive, and the remaining three items are negative. This type of hepatitis B two-half test result indicates acute or chronic hepatitis B;
(5) + - + - + the first, third, and fifth items are positive, and the remaining two items are negative. Commonly known as "triple positive", this type of hepatitis B test result indicates acute or chronic hepatitis B;
(6) + - - + + + the first, fourth and fifth items are positive, and the remaining two items are negative. This is commonly known as "minor triple positive" and indicates acute or chronic hepatitis B.
(7) - - - + + the fourth and fifth items are positive, and the remaining three items are negative. This type of hepatitis B two-half result indicates recovery from acute hepatitis B virus infection or previous infection with the hepatitis B virus;
(8) - + - + + Positive for the second, fourth, and fifth items, and negative for the remaining two items. Indicates a previous HBV infection that has cleared and protective antibodies are present.
(9) - + - - + Positive for the second and fifth items and negative for the remaining three. This type of hepatitis B half-pair result indicates immunity after vaccination against hepatitis B, or after hepatitis B virus infection has recovered. Hepatitis B two-half tests include HBsAg (Hepatitis B surface antigen), anti-HBs (Hepatitis B surface antibody), HBeAg (E antigen), anti-HBe (E antibody), and anti-HBc (core antibody).
1. Hepatitis B surface antigen is the basis for determining whether you are infected with the hepatitis B virus. Positive hepatitis B surface antigen indicates infection with the hepatitis B virus.
2. Hepatitis B surface antibody is the basis for determining whether the body has specific immunity. Positive hepatitis B surface antibody indicates protective immunity against hepatitis B virus infection. A single positive antibody is usually found after vaccination against hepatitis B or after healing from hepatitis B virus infection.
3. Hepatitis B e antigen can be used as a preliminary basis for determining the infectiousness of the hepatitis B virus. Hepatitis B e antigen positive indicates that the infectiousness is strong.
4. Hepatitis B e antibody can be used as a preliminary basis for determining the infectiousness of the hepatitis B virus. Hepatitis B e antibody positive indicates a reduction in viral replication, weak contagious, but can not be concluded that there is no contagious.
5, Hepatitis B core antibody Hepatitis B core antibody positive indicates previous infection with the hepatitis B virus. It can also be found in people who have been vaccinated against hepatitis B or those who have a hidden infection.
2, acute hepatitis B infection stage or chronic hepatitis B surface antigen carriers, weaker infectious.
3, commonly known as hepatitis B small triple positive, the virus replication is weakened, weak contagious, long continued this state can be transformed into liver cancer.
4, previously infected with hepatitis B, now still have immunity, belonging to the atypical recovery period, may also be acute hepatitis B infection.
5, previous hepatitis B infection, belonging to the acute infection recovery period, also a few people are still infectious.
6. Past hepatitis B infection or now in acute infection.
7, previous hepatitis B vaccination or previous hepatitis B infection.
8, Previously infected with HBV, cleared, and protective antibodies present.
9, early acute infection or chronic hepatitis B surface antigen carriers are weakly infectious.
10, chronic hepatitis B surface antigen carriers easy to turn negative or acute infection tends to recover.
11, early hepatitis B infection or chronic carriers, infectious.
12, acute hepatitis B infection tends to recover or chronic carriers. 1, HbsAg (surface antigen): (+) indicates that there is hepatitis B virus infection, may be acute or chronic; or hepatitis B virus carriers.
2, HbeAg (e antigen): (+) indicates that there is hepatitis B virus infection, suggesting that the infectiousness is high and the lesions are active.
3, anti-HBc: (+) indicates hepatitis B virus infection.
4. Anti-HBcIgM: (+) indicates recent infection.
5. Anti-HBcIgG: (+) indicates past infection.
6, Anti-HBe: (+) has hepatitis B virus infection, but is less infectious and relatively stable.
7, anti-HBs: (+) suggests a past hepatitis B virus infection or vaccination against hepatitis B, which has now produced antibodies, which are a protective antibody. Hepatitis B two halves is the most basic test item of hepatitis B examination, which is extremely common in clinic. Hepatitis B two half can only be used to determine the negative and positive of hepatitis B, and cannot accurately quantify the virus.
The misunderstanding in the hepatitis B two-half test is that different negative-positive patterns are often associated with the clinical symptoms or process of hepatitis B patients, and some even carry out quantitative determination of hepatitis B two-half in order to judge the effect of clinical treatment of hepatitis B patients. The reason for this is mainly due to the lack of understanding of the development of the corresponding antigenic antibodies in pathogen-infected patients and the relationship between them and the disease state and antiviral therapy.
The efficacy of hepatitis B treatment is judged by the presence or absence of the pathogen or the amount of the pathogen present, not by the test of the hepatitis B half-pair.
When the treatment is effective, the former is characterized by the disappearance of pathogens, and the latter is characterized by a dynamic decrease in the number of pathogens. Therefore, the effect of treatment is closely related to the presence or absence of pathogens or the number of pathogens present. Antibodies, on the other hand, are specific immune response products to specific antigenic components of pathogens, and even if the pathogens have disappeared or been greatly reduced by antibacterial or antiviral drugs, they may remain in the body for a long period of time or persist in the body, and there is no positive correlation between the presence or absence of the pathogens or the number of pathogens present.
There is a natural lack of positive correlation between HBsAg and the hepatitis B virus. A colleague might ask, what about pathogen antigen? Isn't it part of the pathogen? It should be said that there is a positive correlation between the level of its content and the pathogen. This is a case-by-case analysis. For example, the above mentioned HBsAg and HBeAg can not, because HBsAg in the blood circulation of hepatitis B patients in three forms, namely, round particles, tubular particles and Dan particles, of which only Dan particles in the presence of the hepatitis B virus, but it only accounted for only 0.2% of all the HBsAg, the other vast majority of the empty round particles and tubular particles, so the HBsAg and the hepatitis B virus between the naturally there is a lack of positive correlation.
HBeAg usually has a good positive correlation with the presence of hepatitis B virus, but HBeAg can't be used as an indicator of the efficacy of antiviral therapy in patients with hepatitis B. HBeAg is a major serologic indicator of the infectiousness of hepatitis B patients, and should be used as an indicator of the efficacy of antiviral therapy in patients with hepatitis B. In fact, a lot of people have been doing so, but due to the fact that the hepatitis B virus genome is often prone to spotting in the anterior C region, the HBsAg can be used as a marker of the efficacy of antiviral therapy. However, because the hepatitis B virus genome is often prone to point mutations in the pre-C region, making the absence of HBeAg expression, when the serum HBeAg measurement is negative, but the pathogen is still present in large quantities. Therefore, HBeAg can not be used as an indicator of antiviral efficacy in hepatitis B patients.
In hepatitis B two half, the only real quantitative value of the determination of anti-HBs, but this determination is not used for clinical hepatitis B patient efficacy observation, but for the crowd hepatitis B vaccine effect of the judgment, that is to say, when a person is injected with the vaccine, such as peripheral blood anti-HBs quantitative more than 10 mU / ml, the immunized person with the immunity to the hepatitis B virus immunity, immunity and duration should be proportional to the level of anti-HBs.
Fundamentally speaking, the positive results of hepatitis B two half results reflect only the infection of HBV, and the severity of the clinical condition can be said to have no causal relationship. Hepatitis B two half results of the essence of the body is only a reflection of the results of the immune response after infection with HBV, and the occurrence and development of hepatitis B is not necessarily related to the process. Because the vast majority of HBV-infected people do not show symptoms of hepatitis, but only as carriers, but they will have the same immune response, and get different patterns of two half results. Hepatitis B two-half test examination is a routine test in the hepatitis B examination laboratory, whether it is to check whether infected with hepatitis B virus, or to evaluate the effect of hepatitis B treatment, need to carry out the hepatitis B two-half test. Authoritative liver disease experts pointed out that the following issues should be noted in the hepatitis B two-half test.
1, before doing hepatitis B two half should pay attention to do not drink alcohol.
2, if you are still taking some drugs before the test, then it is best to stop using drugs a day or two before the test so as not to affect the test.
3, before the hepatitis B two-half test, also pay attention to ensure sufficient rest, because poor sleep, tiredness, etc. may affect the accuracy of the test results.
4, the night before the test, it is best not to eat greasy, spicy food.
5, hepatitis B two-half test is not required before fasting, but if you also need to check the liver function, lipids and other items, it is a different story.
