What is HBsAg ELISA test?

What is HBsAg ELISA test?

This test is intended for the qualitative detection of hepatitis B surface antigen (HBsAg) at a sensitivity level of 0.10 IU/mL in human serum or plasma. It is intended to be used by professionals as an aid in the diagnosis of an infection with HBV.

What is HBsAg ELISA reactive?

HBsAg (Hepatitis B surface antigen) – A “positive” or “reactive” HBsAg test result means that the person is infected with hepatitis B. This test can detect the actual presence of the hepatitis B virus (called the “surface antigen”) in your blood.

What is HBsAg chemiluminescence test?

The HBsAg assay is a one-step chemiluminescent enzyme immunoassay coupled with an immune complex transfer method (ICT-CLEIA). The assay detects HBsAg in the absence or presence of anti-HBs antibodies (HBsAb) by performing sample pretreatment.

What is the HBsAg positive range?

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 if ELISA test is positive?

What do the test results mean? If a person tests positive for HIV on the ELISA test, they might have HIV. However, there can be false positives with the ELISA test. This means that test results indicate that the person has HIV when they actually do not.

What is an ELISA test used for?

ELISA stands for enzyme-linked immunoassay. It is a commonly used laboratory test to detect antibodies in the blood. An antibody is a protein produced by the body’s immune system when it detects harmful substances, called antigens.

What is the normal range for HBV DNA?

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).

Which vial is used for HBsAg?

How long can hepatitis B patient live?

A “silent disease.” It can live in your body for 50+ years before you have symptoms. Responsible for 80 percent of all liver cancer in the world. Harder to fight off the younger you are; 90 percent of babies will go on to develop a chronic infection compared to 5 to 10 percent of adults.
