Blood Test For Hepatitis C Screening

Who Should Get Tested For Hepatitis C

Hepatitis C Screening

The CDC recommends that you get tested at least once no matter what. Definitely get screened if any of these things apply to you:

  • You were born between 1945 and 1965.
  • You use or inject drugs.
  • You have ever injected drugs — even if it was just once or a long time ago.
  • Youâre on kidney dialysis.
  • You have abnormal alanine aminotransferase levels .
  • You had a blood transfusion, blood components, or an organ transplant before July 1992.
  • Youâve ever gotten clotting factor concentrates made before 1987.
  • You received blood from a donor who later tested positive for hepatitis C virus.
  • Youâre a health care worker, first responder, or have another job that exposes you to HCV-infected needles.
  • You were born to a mother with HCV.

Dried Blood Spot Testing

Dried Blood Spot testing uses drops of blood from the end of your finger. It doesnt use a needle and syringe and you can do it free of charge in the privacy of your home. Your details and the results are kept private. If your test result shows you have hep C, the people who give your results can help you access hep C treatment and cure.

Besides Hcv Testing What Other Tests Might Be Done

Healthcare practitioners may also order a liver panel, which is a group of tests that help assess the health of your liver. Liver tests such as ALT and AST may be used to detect ongoing liver injury. You will likely be checked to see if you are immune to hepatitis A and hepatitis B, and if not, you will be offered vaccination, since infection with these other viruses can further damage your liver. Other tests such as albumin, prothrombin time, and bilirubin can also be used. They are typically normal unless you have developed cirrhosis. Sometimes a liver biopsy may be performed to determine the severity of liver damage. If you are going to be treated, you will be checked for exposure or infection with hepatitis B virus, as HCV treatment can cause a flare-up of hepatitis B.

Recommendations Regarding Linkage To Care

All persons identified with active hepatitis C infection should be linked to a medical provider who can provide competent and comprehensive management of HCV. Available data suggest that in the current era, nonspecialists can effectively manage HCV, especially with back up and consultation for more complicated issues. The management of patients with decompensated cirrhosis should always involve a hepatologist. In addition, persons with HCV who have renal insufficiency or extrahepatic complications of HCV infection will likely require referral to a specialist. An individual with a positive HCV antibody test but negative HCV RNA level does not require a referral for further evaluation and management of HCV infection.

NEW TITER OF ANTIBODY HEPATITIS B

A blood test, called an HCV antibody test, is used to find out if someone has ever been infected with the hepatitis C virus. The HCV antibody test, sometimes called the anti-HCV test, looks for antibodies to the hepatitis C virus in blood. Antibodies are chemicals released into the bloodstream when someone gets infected.

Test results can take anywhere from a few days to a few weeks to come back. Rapid anti-HCV tests are available in some health clinics and the results of these tests are available in 20 to 30 minutes.

Screening For Hepatitis C

Although most clinicians have extensive experience with the diagnosis and treatment of disease, they have limited experience with screening for disease. Screening is characterized by interventions in a group of individuals with no signs or symptoms of disease to identify unrecognized disease. The hope is that by identifying the disease before the onset of signs or symptoms, morbidity and possibly mortality can be reduced. Screening is not intended to be diagnostic its main purpose is to detect the possibility of disease. The fact that screening is typically performed on healthy individuals can account for some of the limited experience on the part of clinicians.

The 2 most common types of screening are universal screening and selective screening. Universal screening involves screening all individuals in a certain category, such as all individuals above a certain age. Selective screening involves screening individuals who have a high risk for the disease, such as having family members with a known hereditary disease.

The World Health Organization has issued the following guidelines for screening:

Currently, the US Centers for Disease Control and Prevention and the US Preventive Services Task Force recommend screening for hepatitis C for 2 groups of individuals:

Hepatitis B Antibody And Antigen Test

Most people who come into contact with hepatitis B will clear the virus during the first six months of their infection. During this phase, the condition is known as acute hepatitis B. People who do not clear the virus after six months will be diagnosed as having chronic hepatitis B, which can cause liver damage.

Tests are carried out to look for antigens and antibodies in your blood. The results of these may indicate several possibilities:

  • you have been infected by the virus in the past
  • you have a new infection
  • the infection is likely to go away by itself
  • the infection has become chronic .

These antigens and antibodies are known as serological or viral markers. Doctors will look for markers in your blood over the course of your infection to see how the virus is progressing and/or responding to treatment. In particular, finding surface and e antigens known as HBsAg and HBeAg and their corresponding antibodies will help your healthcare team understand more about the pattern of your disease, and how its likely to progress

Hepatitis C Is Often Asymptomatic

Using Elisa And Hcv Rna Tests Together:

  • Negative ELISA = No hepatitis C antibodies found in blood. You are probably not infected with HCV.
  • Positive ELISA = You may have HCV infection. However, it is possible this is a false-positive. More testing is required.
  • Negative HCV RNA = No active HCV infection.
  • Positive HCV RNA = Active HCV infection.

Hepatitis C Screening: Questions For The Doctor

  • Talking with the Doctor
  • Hepatitis C Screening: Questions for the doctor
  • Hepatitis C is a serious liver disease caused by the hepatitis C virus . The most common way to get hepatitis C is by coming into contact with the blood of someone who has it.

    Everyone ages 18 to 79 needs to get tested for hepatitis C at least once.

    Many people who have hepatitis C live for years without feeling sick. But the virus can still damage your liver even when there arent any symptoms. You could also spread the virus to others without knowing it.

    The only way to know for sure if you have hepatitis C is to get a blood test. Medicine can cure most cases of hepatitis C.

    What Happens During A Hepatitis Panel

    A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

    You may also be able to use an at-home kit to test for hepatitis. While instructions may vary between brands, your kit will include a device to prick your finger . Youll use this device to collect a drop of blood for testing. For more information on at-home testing for hepatitis, talk to your health care provider.

    Counseling Practices That Educate Support And Motivate Clients Undergoing Screening

    Clients might need help deciding whether to get screened, understanding the test results, and determining their next steps. Even when services offered through the substance abuse treatment program are limited, discussing testing with clients presents an opportunity for counselors to motivate clients for change by confronting substance use and by making choices that improve their overall health. However, this may also be true when services are offered on-site through substance abuse treatment programs. A study at one methadone clinic that offered hepatitis screening and vaccination revealed that although the majority of clients completed screening , only 54.7 percent of clients who lacked for hepatitis A received vaccinations and only 2.9 percent of clients who lacked immunity for received vaccinations .

    The Consensus Panel makes the following general recommendations while recognizing that, in some programs, the counselors role may be limited:

    What Does A Reactive Hcv Antibody Test Result Mean

    A reactive or positive antibody test means you have been infected with the hepatitis C virus at some point in time.

    Once people have been infected, they will always have antibodies in their blood. This is true if they have cleared the virus, have been cured, or still have the virus in their blood.

    A reactive antibody test does not necessarily mean that you currently have hepatitis C and a follow-up test is needed.

    Can This Test Be Done At My Healthcare Practitioners Office

    Maybe. There are rapid HCV antibody tests available that can be done at the point of care , in settings such as your healthcare practitioners office, community health clinics, and emergency rooms. They provide results in about 20 minutes. However, a positive result requires confirmation of active disease with an HCV RNA test, which is performed in a laboratory.

    How Hepatitis C Virus Is Diagnosed

    Hepatitis C virus is usually diagnosed with blood tests. An antibody test can detect whether your body has had to fight off HCV infection. A blood test which measures the virus in your blood confirms the diagnosis, but results take longer. Sometimes, liver function tests, imaging studies, or a biopsy can support or confirm the diagnosis as well.

    As of March 2020, the U.S. Preventive Services Task Force recommends HCV screening for all adults ages 18 to 79. The CDC also updated their guidelines in April 2020, recommending screening for all adults and pregnant women.

  • people who received an organ transplant before July 1992
  • people who were notified that they received blood from a donor who later tested positive for HCV infection
  • Children born to mothers with HCV infection
    • Any person who requests hepatitis C testing should receive it, regardless of disclosure of risk, because many persons may be reluctant to disclose stigmatizing risks

    Hepatitis C Testing And Diagnosis

    Should I get tested for hepatitis C?

    Doctors will start by checking your blood for:

    Anti-HCV antibodies: This blood test is the first — and sometimes only — one you may get. Also called the ELISA screen, it checks for antibodies that your body releases to fight the virus. These are proteins your body makes when it finds the hep C virus in your blood. They usually show up about 12 weeks after infection. Your test will be either negative or positive for antibodies. It usually takes a few days to a week to get results, though a rapid test is available in some places.

    What the results mean

    Negative . This is when your blood shows no signs of HCV antibodies. Most of the time, thatâs because you never came in contact with the virus and you do not have hep C.

    Sometimes, your negative result can be false, meaning you have HCV. That may happen if you:

    • Took the test too soon after your exposure. This test checks for only HCV antibodies, which can take several months to appear.
    • Have HIV, a donated organ, or other conditions that weaken your immune system, which can suppress your antibodies
    • Get hemodialysis for kidney problems

    If youâve been exposed in the last 6 months, youâll need to be retested.

    Positive . This means youâve been infected with HCV. But false positives are surprisingly common. More than 1 in 5 people who test positive donât actually have hepatitis C. Possible reasons include:

    What Is An Hcv Antibody Test

    An HCV antibody test is used to determine whether youve contracted the hepatitis C virus.

    The test looks for antibodies, which are proteins made by the immune system that are released into the bloodstream when the body detects a foreign substance, such as a virus.

    HCV antibodies indicate exposure to the virus at some point in the past. It can take anywhere from a few days to a few weeks to get results back.

    . The blood panel will either show that you have a nonreactive result or a reactive result.
