What does anti-HBe reactive means?
When the anti-HBe is also reactive, this means the individual is in the process of healing and is less contagious. A non-reactive HBeAg result (with a reactive anti-HBe result) in a person with hepatitis B indicates that the infection is in its initial phase, before peak replication of the virus.
What is the normal range of anti-HBe?
Any value between 1 and 5 s/c is indeterminate and should be repeated. For hepatitis B surface antibody (anti-HBs), a level less than 5 mIU is considered negative, while a level more than 12 mIU is considered protective. Any value between 5 and 12 mIU is indeterminate and should be repeated.
Where is HBeAg located?
HBeAg is an antigen that can be found between the icosahedral nucleocapsid core and the lipid envelope. It is the antigenic determinant that is closely associated with the nucleocapsid of HBV. It also circulates as a soluble protein in serum.
What is the meaning of HBe?
Summary. Listen. Hemoglobin E (HbE) disease is a mild, inherited blood disorder characterized by an abnormal form of hemoglobin, called hemoglobin E. People with this condition may have very mild anemia , but the condition typically does not cause any symptoms.
Can you become immune to hepatitis B?
In 90% of persons who become infected as adults with hepatitis B, the immune system successfully fights off the infection during the acute phase — the virus is cleared from the body within 6 months, the liver heals completely, and the person becomes immune to hepatitis B infection for the rest of their life.
What is the minimum viral load of hepatitis B?
Labs usually measure down to less than 200 IU/mL. Below the threshold, the viral load is considered “undetectable” – something everyone with chronic hepatitis B wants to hear.
Is HBsAg the same as HBeAg?
Hepatitis B e antigen (HBeAg) is a small polypeptide that exists in a free form in the serum of individuals during the early phase of hepatitis B infection, soon after hepatitis B surface antigen (HBsAg) becomes detectable. Serum levels of both HBeAg and HBsAg rise rapidly during the period of viral replication.
What is e hemoglobin?
Hemoglobin E trait is an inherited blood disorder. That means it is passed down through your parent’s genes. It leads to an abnormal form of hemoglobin that may cause mild anemia. It occurs most often in people of Southeast Asian descent.
What does low hemoglobin F mean?
High and low values A very low level of hemoglobin A and a high level of hemoglobin F may mean a more severe form of thalassemia. High levels of hemoglobin F may be seen in a rare condition called hereditary persistence of fetal hemoglobin. Hemoglobin S in moderate amounts can mean that sickle cell trait is present.
