What is a positive anti-HBs?
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.
How do you read anti-HBs report?
Report any of the numerical results that are ≥ 5.00 and <12.0 mIU/mL. If 2 of 3 results are ≥12.0 mIU/mL, the sample is “Positive” for anti-HBs. Report any of the numerical results that are ≥12.0 mIU/mL. If 2 of 3 results are < 5.00 mIU/mL, the sample is “Negative” for anti-HBs.
What is HBs negative?
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. In most cases this means that you will recover within 6 months.
What is the normal range of hepatitis B viral load?
HBV: Hepatitis B virus. # Normal values: ALT: Males: 10-40 U/L; Females: 7 – 35 U/L; AST: Males: 15 – 40 U/L; Females: 13 – 35 U/L. HBeAg-positive patients had significantly higher ALT levels (mean 170.3 ± 391 IU/L) compared to HBeAg-negative patients (mean 53.9 ± 169.4 IU/L), p < 0.0001 (Table 2).
What if my hep B titer is negative?
Negative. If your HBsAb test is negative, it can mean many different things—but, in general, it means you are not immune to the Hepatitis B virus. If your HBsAb test is negative, your healthcare provider may recommend getting the vaccine.
What is the normal range of HBV DNA quantitative?
Normal range for this assay is Not Detected. The quantitative range of this assay is 1.00-9.00 log IU/mL (10-1,000,000,000 IU/mL).
What does hepatitis B surface antibody QL borderline mean?
Borderline results may indicate a low level of antibody that has clinical significance. Patient’s immune status should be further assessed by considering other clinical information or retesting another specimen drawn at a later time.
What is a good viral load count?
What the Results Mean. A high viral load is generally considered about 100,000 copies, but you could have 1 million or more. The virus is at work making copies of itself, and the disease may progress quickly. A lower HIV viral load is below 10,000 copies.
What is HBs Ag test?
Hepatitis B surface antigen (HBsAg) is a blood test ordered to determine if someone is infected with the hepatitis B virus. If it is found, along with specific antibodies, it means the person has a hepatitis B infection.
What is the anti-HBs positive value?
The anti-HBS positive value, which indicates that the person is protected against hepatitis B virus for life, may be developed by vaccination method or due to infection. Although the anti-HBS value is higher than 5 mIU/ml, it is accepted as positive, but the value between 5 to 12 mIU/ml after vaccination shows that the vaccine does not retain.
What is the normal range of anti-Hb levels?
Anti-HBs from 5-12 mIU/mL: Inconclusive results and the test should be repeated. However, there is no standardization of these values so it is advisable to check the manufacturers values; it is the reason values are mainly reported as positive or negative.
What are anti-HBs used to monitor?
Anti-HBs is also used to monitor the convalescence and recovery of HBV infected individuials. The presence of anti-HBs after acute HBV infection and loss of Hepatitis B virus surface antigen (HBsAg) can be a useful indicator of disease resolution. Detection of of anti-HBs in an asymptomatic individual may indicate previous exposure to HBV.
What is HBsAg surface antigen?
Hepatitis B surface antigen (HBsAg) is a protein on the surface of hepatitis B virus. Hepatitis B surface antibodies are produced by the body’s immune system in response to HBsAg. The presence of adequate hepatitis B surface antibodies in the blood indicates protection against hepatitis B virus infection.
