What is serology test for hepatitis B?

The diagnosis of hepatitis B virus (HBV) infection is established through serological testing. The diagnostic panel for hepatitis B serology – allowing determination of susceptibility, active infection, or immunity through vaccination or past infection – includes testing for: hepatitis B surface antigen (HBsAg)

What does a positive hepatitis serology mean?

IgM antibody to hepatitis B core antigen (IgM anti-HBc): Positivity indicates recent infection with hepatitis B virus (<6 mos). Its presence indicates acute infection. Tests. Results.

Is hepatitis B detected in blood test?

Blood tests can detect signs of the hepatitis B virus in your body and tell your doctor whether it’s acute or chronic. A simple blood test can also determine if you’re immune to the condition. Liver ultrasound. A special ultrasound called transient elastography can show the amount of liver damage.

What are the serological markers for hepatitis B?

HBV serological markers [antibody to HBV core antigen, HBV surface antigen (HBsAg), antibody to HBV surface antigen, HBV ‘e’ antigen (HBeAg), and antibody to hepatitis B ‘e’ antigen] and plasma HBV DNA viral load were measured retrospectively on stored baseline samples.

What is a positive hepatitis B result?

A positive or “reactive” test indicates that a person may have been infected with the hepatitis B virus at some point in time. This test is often used by blood banks to screen blood donation, however, all three test results are needed to make a diagnosis.

What is hepatitis B normal range?

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.

What happens if you test positive for hepatitis B?

A positive anti-HBs (or HBsAb) test result means you are “immune” and protected against the hepatitis B virus and cannot be infected. You are not infected and cannot spread hepatitis B to others.

Can hepatitis B positive became negative?

Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you. Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV.

Can hepatitis B become negative?

Patients who become HBsAg negative and develop antibody to HBsAg (anti-HBs) are diagnosed as having resolved hepatitis B [3,4]. This is an uncommon phenomenon in chronic HBV infection. During stage HBV DNA may still be detectable by PCR in serum and more often in the liver.

Can the liver repair itself from hepatitis B?

Barring complications, the liver can repair itself completely and, within a month, the patient will show no signs of damage. However, sometimes the liver gets overwhelmed and can’t repair itself completely, especially if it’s still under attack from a virus, drug, or alcohol.
