How do you read HCV reports?
An HCV antibody test is typically reported as “positive” or “negative.”…What does the test result mean?
| HCV Antibody | HCV RNA | Interpretation |
|---|---|---|
| Positive or weakly positive | Negative | Past infection or no infection (false-positive screen, most are weakly positive) |
| Positive | Positive | Current, active infection |
What is HCV normal range?
Normal range for this assay is “Not Detected”. The quantitative range of this assay is 10 – 100,000,000 IU/mL (1.0 – 8.0 log IU/mL).
What is HCV Ab interpretation?
HCV antibody reactive A repeatedly reactive result is consistent with current HCV infection, or past HCV infection that has resolved, or biologic false positivity for HCV antibody. Test for HCV RNA to identify current infection.
What is the confirmatory test for HCV?
All patients suspected of having infection with HCV should be tested for antibody to HCV (anti-HCV) using an EIA (enzyme immunoassay) screening test. In low-risk patients with a positive EIA test, confirmatory testing with the recombinant immunoblot assay (RIBA) should be performed.
What happens if you have a positive RIBA test for HCV?
If the RIBA HCV test also showed a positive result, this confirmed that you had hepatitis C antibodies and had been exposed to HCV. The next step was to test for HCV RNA (viral load) to see if the hepatitis C virus was still present in your body.
What do you need to know about the RIBA blood test?
The hepatitis C (HCV) RIBA blood test is used to check whether you have traces of antibodies for the virus that causes hepatitis C infections in your body.
How to interpret results of hepatitis C test?
Interpretation of Results of Tests for Hepatitis C Virus (HCV) Infection and Further Actions Interpretation of Results of Tests for Hepatitis C Virus (HCV) Infection and Further Actions TEST OUTCOME INTERPRETATION FURTHER ACTIONS HCV antibody nonreactive No HCV antibody detected Sample can be reported as nonreactive for HCV antibody.
What kind of blood test is used to test for HCV?
The Recombinant ImmunoBlot Assay (RIBA) is a blood test that detects antibodies to the hepatitis C virus (HCV). It was used for many years as a secondary confirmation test if a first-line screening test for HCV (called the ELISA hepatitis C antibody test) came back positive or indeterminant.
