What does HBsAb positive mean?
■ Anti-HBs [sometimes written as HBsAb] (antibody to hepatitis B surface antigen): when this is “positive” or “reactive,” it means the person is immune to hepatitis B infec- tion, either from vaccination or from past infection.
What is normal HBsAg value?
For example, a hepatitis B surface antigen (HBsAg) level of less than 1 s/c is considered negative, while a level of more than 5 s/c is considered positive. Any value between 1 and 5 s/c is indeterminate and should be repeated.

What is the difference between HEPB and Hepc?
The most significant difference between hepatitis B and hepatitis C is that people may get hepatitis B from contact with the bodily fluids of a person who has the infection. Hepatitis C usually only spreads through blood-to-blood contact.
What does a negative HBsAb mean?
If your other hepatitis B tests (both HBsAb and other hepatitis tests) are negative, it means you are either not infected or that you are in the very early incubation stage of infection, prior to the point at which antibodies would be formed.
What is HBeAg negative?
Hepatitis B e antigen (HBeAg)‐negative CHB is also referred to as anti‐HBe‐positive and precore mutant hepatitis. Patients with HBeAg‐negative CHB have a naturally occurring mutant form of HBV that does not produce HBeAg because of a mutation in the precore or core promoter region of the HBV genome.
How long is hepatitis B window period?
The interval between disappearance of HBsAg and appearance of anti-HBs is known as the window period and may last as long as 6 months. Detection of anti-HBs usually indicates clinical recovery and subsequent immunity to HBV.
What are the 5 types of hepatitis?
There are 5 main hepatitis viruses, referred to as types A, B, C, D and E. These 5 types are of greatest concern because of the burden of illness and death they cause and the potential for outbreaks and epidemic spread.
Which type of hepatitis is more severe?
Hepatitis Delta is considered to be the most severe form of hepatitis because of its potential to quickly lead to more serious liver disease than hepatitis B alone. Of the 292 million people living with chronic hepatitis B, approximately 15-20 million are also living with hepatitis D.

Can you be naturally immune to hepatitis B?
Conclusion: Individuals who are naturally immune against HBV may experience a decrease in Ab titer. Their responses to booster vaccinations varied widely. It is possible that elderly patients with natural immunity require closer surveillance. We provide recommendations for surveillance in these patients.
What is a dangerously low hemoglobin level?
- If it gets more severe and causes symptoms, your low hemoglobin count may indicate you have anemia. A low hemoglobin count is generally defined as less than 13.5 grams of hemoglobin per deciliter (135 grams per liter) of blood for men and less than 12 grams per deciliter (120 grams per liter) for women.
What is HbA1c screening?
- An HbA1c test may be used to check for diabetes or prediabetes in adults. Prediabetes means your blood sugar levels show you are at risk for getting diabetes. If you already have diabetes, an HbA1c test can help monitor your condition and glucose levels.
