What Is a Hepatitis Blood Test?

The five items of hepatitis B are also called two pairs of HBV, including hepatitis B surface antigen (HBSAg), hepatitis B surface antibody (HBSAb / anti-HBs), e-antigen (HBeAg), e-antibody (HBeAb / anti-HBe), and core antibody (HBcAb / Anti-HBc). The five tests of hepatitis B are to extract the venous blood of the patient and detect the serological signs of hepatitis B virus in the blood.

Five indicators of hepatitis B

The tests for HBV are relatively simple. Generally, the results can be obtained in the afternoon, and one day is enough. If you are a carrier of hepatitis B, it is recommended to check regularly every three months to about June, and you do not need to check too frequently.

Five items of hepatitis B include

1. HBsAg (Hepatitis B surface antigen) It is the shell material of hepatitis B virus and is not infectious. its

1. The first five indicators of hepatitis B are positive: those who are infected with hepatitis B virus, who are associated with the 35th positive, are the big three positives, and those who are 45 positive are the small three positives. In either case, as long as it is accompanied by item 2

Reference range of the five items of hepatitis B:

Hepatitis B surface antigen (HBsAg) -0--0.5ng / mL HBsAg is greater than 0.5ng / mL +

Hepatitis B surface antibody (HBsAb) -0--10mIU / mL HBsAb is greater than 10mIU / mL + (not infected with antibodies, 0 ~ 10mIU / mL weak positive)

Hepatitis B e antigen (HBeAg) -0--0.5PEI / mL HBeAg is greater than 0.5PEI / mL + (less than 0.5PEI / mL negative-)

Hepatitis B e antibody (HBeAb) -0--1.5PEI / mL e antibody is greater than 1.5P / mL +

Hepatitis B core body (HBcAb) -0--0.9PEI / mL

Many patients with hepatitis B have undergone treatment, and the hepatitis B virus indicators have changed. The major three positives have changed to the minor three positives and the HBV DNA has become negative. However, as soon as treatment is stopped, the viral indicators change back to the original: some patients have not received any treatment, and the viral indicators are always Change, sometimes positive, sometimes negative. Some patients have a quantitative examination of viral indicators. The values are high and low. What is going on? The liver disease experts analyze the reasons as follows:

The immune function of patients with chronic hepatitis B is paralyzed. No matter how much or how much the virus replicates, liver function remains normal, liver tissue damage is relatively light, and viral indicators are relatively stable. If the body's immune function can recognize the hepatitis B virus and begin to clear the virus, but the removal ability is not strong, and the virus cannot be completely removed and eliminated, the hepatitis B virus indicators will change, from yin to yang, high to low, and liver function will follow Changed. Hepatitis B virus mutation. Most patients

1 Turn overcast with positive effects and improved nature. Some patients have negative conversion of hepatitis B virus indicators through medication or other methods. The most common is hepatitis B

Hepatitis B five positive 45 means that it is the recovery period of acute hepatitis B virus infection, or has been infected with hepatitis B virus. However, if the e-antibody has not existed for more than six months and the antibody has not been produced, it means that the hepatitis B virus mutation is likely to cause cirrhosis.

Hepatitis B five items 45 positive The fourth item is the hepatitis B E antibody, which indicates that the replication of the hepatitis B virus has been inhibited to a certain degree; the fifth item is the hepatitis B core antibody, which indicates that the hepatitis B virus has been infected or is being infected with the hepatitis B virus.

HBsAg anti-HBs HBeAg anti-HBe anti-HBc

Pre-marital medical examination items include medical history, physical examination, routine auxiliary examination and other special examinations. Therefore, even patients with hepatitis B should not worry about affecting marriage, and avoid medical treatment. Hepatitis B patients should regularly go to a regular liver disease hospital for a comprehensive and systematic examination, and carry out scientific and systematic treatment according to the condition.

Can hepatitis B get married? Others were very unfortunate. When they stepped into the marriage hall cheerfully, they were suddenly found to be infected with the hepatitis B virus, and they suddenly felt dark. For those who are about to marry, the detection of hepatitis B has little relationship, because it does not affect the marriage event between the two parties The state did not say that hepatitis B patients cannot marry. And it is not mandatory for the marriage check. However, if hepatitis B patients have abnormal liver function and high viral DNA content, then it is recommended not to get married for the time being, because sexual life after marriage and daily contact are easily contagious, and the life of husband and wife will aggravate the patient's condition.

Hepatitis B virus can be transmitted through the blood and placenta and is transmitted from the birth canal during pregnancy. In the United States, approximately 3,500 babies become carriers of hepatitis B virus each year. Hepatitis B virus causes infants to become liver-large and produce various clinical or subclinical signs. Among them, 25% of infants often die of cirrhosis and liver cancer when they reach adulthood.

China is a high-incidence area of hepatitis B. At least 50-60 million women are carriers of hepatitis B virus. General screening of hepatitis B virus indicators for pregnant women, or pregnant women actively checking for hepatitis B virus indicators to detect those who are infected, so that their newborns will be vaccinated and injected with high-priced immunoglobulins within 24 hours of birth, 1 month and 6 Hepatitis B vaccines can be used to boost the hepatitis B vaccine at least 80% -90% of infants. Therefore, a census of hepatitis B virus in pregnant women is conducive to eugenics and childbirth, and is of benefit to future generations.

Are there five items to check for hepatitis B before pregnancy?

Hepatitis B virus replication is active, highly infectious, severe liver damage, and obvious symptoms, which are the common characteristics of the hepatitis B. During this period, patients are easily infected with family, friends, and the outside world. During this period, the patient's utensils must be disinfected and isolated to prevent others from coming into contact with the patient's blood, menstrual blood, sweat, and milk.

Are there five items to check for hepatitis B before pregnancy? Strict inspection is needed before pregnancy. If you are determined to be a carrier of hepatitis B virus, and have a large Sanyang virus, or have a high hepatitis B virus load, you should treat it as soon as possible. You should consider fertility when the large Sanyang turns negative. .

If the hepatitis B patient is already pregnant, patients with a clear diagnosis will be treated differently depending on the condition, and active and passive immunization methods will be used to block the hepatitis B virus. For patients with hepatitis B who have given birth, please do not breastfeed. Breastfeeding is a non-negligible way of vertical transmission of hepatitis B virus. Therefore, it is not advisable to carry out breastfeeding for carriers of hepatitis B virus.

There is still no clear price. According to the consumption level in different regions and regions, the inspection preparations and methods are different, and the inspection costs will be different. The state did not specify a price, but the general cost of the five tests for hepatitis B is 35-70 yuan, of which the core antigen test is about 20 yuan, and the other four items are 15-20 yuan.

Hepatitis B is a common infectious disease, also known as serum hepatitis. It is caused by the infection of hepatitis B virus. Many patients mistakenly regard the hepatitis B virus indicators "big three positives" and "small three positives" as serious. Sign, this is extremely wrong. Studies have shown that "big three positives and small three positives" have nothing to do with the severity of hepatitis B patients. In order to enable patients to know what stage their illness is in, the criteria for diagnosing hepatitis B are introduced to everyone:

1. Chronic virus carrying stage. These people generally have no obvious discomfort themselves and can live and work like normal people. These people's liver function tests, B-ultrasound and other imaging tests were basically normal or mildly abnormal.

Second, mild chronic hepatitis. These patients have mild discomfort, manifested by fatigue, liver discomfort, and decreased appetite. Hepatic function was mildly abnormal (transaminase 40-120 units / liter, serum bilirubin 17.7.7-34 micromol / liter), and hepatitis B virus indicators (HBV surface antigen, hepatitis B e antigen, HBVDNA, etc.) were positive.

Third, moderate chronic hepatitis. The clinical symptoms of these patients are more prominent, including fatigue, loss of appetite, and yellowing of the sclera (eyes). Hepatic function was significantly abnormal (more than 120-400 units / liter of transaminase and more than 35-85. 5 micromoles / liter of serum bilirubin).

Fourth, severe chronic hepatitis. The symptoms of these patients are very obvious, showing symptoms of hepatitis B, such as severe fatigue, malaise, and yellowing of the whole body. Hepatic function is severely abnormal, transaminase is greater than 400 units / liter, serum bilirubin is greater than 85.5 micromoles / liter, albumin is less than 32 g / liter, and prothrombin activity is reduced to 40% -60%.

Warm reminder: Many patients with hepatitis B will have negative, doubt, and anxiety during the treatment process. The long treatment process is one of the main reasons, and the other is that they cannot clearly understand the development of their condition. So clearly knowing the development of your condition is very important for the treatment of hepatitis B.
