What Does Non Reactive Mean On A Hepatitis C Test

Educating Clients About Viral Hepatitis

NY Cures Hep C Campaign: âLearn about Hepatitis C Testingâ? Animated Video

Clients may believe they know about viral , but their understanding of the disease may not be accurate. It is easy to confuse the three main types of viral , B, and C. Clients may have formed impressions based on limited or incorrect information. Counselors should briefly describe hepatitis A, B, and C, including their prevalence, , and relationship to drug use, as well as to other infections, such as HIV and sexually transmitted diseases. Specific strategies for speaking with clients include:

  • Speak clearly and keep the message simple, focused, and brief.
  • Use language, examples, and concepts that the client understands.
  • Use appropriate visual aids.
  • Frame numerical statements in terms that are easy to visualize. Say 5 out of 100 people rather than 5 percent of the population say more than half instead of the majority.
  • Repeat the information at different times in different ways. The average client retains only approximately one-third of what he or she is told. Summarize essential points.
  • Pay attention to a clients response to the information. For example, if a client stiffens his or her posture, consider saying, I notice that this topic seems to make you uncomfortable. It does for a lot of people. Please tell me what youre feeling right now. Id really like to help you with this.
  • Use the opportunity to describe the potential detrimental effects of alcohol and other substance use on the liver of a person who is infected with HCV.

Hepatitis B Blood Tests

The Hepatitis B Panel of Blood Tests

Only one sample of blood is needed for a hepatitis B blood test, but the Hepatitis B Panel includes three parts. All three test results are needed to fully understand whether a person is infected or not. Below is an explanation of the 3-part Hepatitis B Panel of blood test results.

  • HBsAg – 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 in your blood. If a person tests positive, then further testing is needed to determine if this is a new acute infection or a chronic hepatitis B infection. A positive HBsAg test result means that you are infected and can spread the hepatitis B virus to others through your blood.
  • anti-HBs or HBsAb – A “positive” or “reactive” anti-HBs test result indicates that a person is protected against the hepatitis B virus. This protection can be the result of receiving the hepatitis B vaccine or successfully recovering from a past hepatitis B infection. This test is not routinely included in blood bank screenings. A positive anti-HBs 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.
  • What The Quantitative Results Mean

    The quantitative test results indicate the exact amount of HCV in your blood. This number helps your doctor confirm whether you have a high or low viral load.

    Measuring your viral load before treatment allows your doctor to monitor your viral load during and after treatment.

    The viral load measurement doesnt indicate how severe your HCV infection or cirrhosis is. Your doctor will need to take a biopsy, or tissue sample, from your liver to learn more about how your liver has been affected by an HCV infection.

    The viral load results from the quantitative PCR test can range from 15 to 100,000,000 IU/L.

    If your results are:

    • Fewer than 15 IU/mL: The virus is detected, but the amount cant be measured exactly. You may need to return later for another test to see if the measurement changes.
    • Fewer than 800,000 IU/mL: A low viral load is detected.
    • More than 800,000 IU/mL: A high viral load is detected.
    • More than 100,000,000 IU/mL: The virus is detected and active infection is taking place.
    • Inconclusive: HCV RNA cant be measured, and a new sample needs to be taken.

    Can Hepatitis C Be Treated

    Yes, since 2010 enormous progress has been made in the treatment of chronic hepatitis C. New therapies called direct-acting antivirals are pills that act on the virus itself to eradicate it from the body, unlike older medicines like interferon injections which work by stimulating an immune response. These new treatments are very effective and can achieve cure rates of over 90%. In most situations now, there is no need for interferon, which was responsible for many of the side effects previously associated with HCV treatment. The new treatment combinations require shorter treatment durations , have reduced side effects and appear to be effective at all stages of the disease.

    Because these new therapies are very new, they remain very expensive. As such, drug coverage from both government and private companies may require that your liver disease has progressed to a certain stage before they are willing to cover the cost of these drugs.

    Your primary care physician may refer you to a specialist to determine whether you are eligible for treatment. A specialist will help you decide which drug therapy is best for you based on the severity of your liver disease, your virus genotype and whether or not you have been treated in the past.

    Addressing Hepatitis For The First Time

    Recommendations for Identification and Public Health ...

    It is crucial that a treatment counselor or health professional use a nonjudgmental and compassionate tone. Clients need to feel comfortable disclosing information about their health and risky behaviors. The following strategies can help initiate the conversation:

    • Display posters, literature, or other -related items that could help prompt the client to ask questions about hepatitis. .
    • Assess clients ability to discuss , based on their degree of openness in the counseling session, the amount of detail they provide in their responses, and the length of the therapeutic relationship.
    • Raise the subject in a way that avoids making clients feel defensive or afraid. Consider introducing the subject by making parallels with other conditions that have been discussed. Say, for example, You said you were tested for HIV several times. Were you ever tested for viral ? or You mentioned that your friend is sick with HIV. Have you been tested for HCV or HIV? Tell me about those tests.
    • Be patient and allow time for multiple, short conversations about the subject. This might ease feelings of fear, anxiety, or shame.

    What To Expect During Testing

    A healthcare provider will take a blood sample for analysis.

    Before the test, let them know if youre uncomfortable with certain needles or if youve ever passed out at the sight of blood. They can give you a snack to reduce your risk of fainting.

    The needle may sting a little as it enters your skin, and you may have a bruise on the site of the draw for a few days.

    Results are usually available within a few days or a few weeks at most.

    The HCV RNA PCR test is conducted through a process called polymerase chain reaction . There are two approaches to this process: qualitative and quantitative.

    Questions For Your Doctor About Test Results

    Patients receiving hepatitis C testing may find it helpful to ask questions about their test results. Questions to consider include:

    • What type of hepatitis C test did I receive?
    • What was my test result?
    • How do you interpret the results of the hepatitis C tests that I had?
    • Do I need any follow-up tests based on my test result?

    Hepatitis C Testing And Diagnosis

    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:

    Other Tests For Diagnosing Hepatitis C

    Hepatitis C

    Before recommending a treatment plan, your doctor will likely conduct other tests. The six major strains, or genotypes, of HCV respond differently to different treatments, so your doctor will conduct another blood test that determines your HCV genotype.

    You can be infected with more than one genotype at a time. Genotypes 1, 2, and 3 are the most common in the United States.

    Discussing Screening Results With Clients

    The medical personnel who ordered or arranged the screening test, not counselors, usually explain the results. Hepatitis screening should be part of the intake physical examination in an opioid treatment program, and medical personnel may report the results. However, the client may want to discuss the results with the counselor or ask the counselor questions.

    Anxiety might interfere with some clients ability to comprehend or retain information, which might need to be repeated.

    Suggestions for conversations with clients when the test results are negative include the following:

    • Explain results clearly and simply: So the HCV screening result was negative? This means that, as of 6 months ago, you did not have .
    • Emphasize that a negative result to an HCV test does not indicate to and that the client should take precautions to avoid . If a relapse to drug use occurs, advise clients to avoid sharing any drug paraphernalia or equipment. Specify that this includes cookers, cotton, water, needles, syringes, pipes, and straws.
    • Emphasize the importance of getting HAV and HBV vaccinations. Provide information about the availability of low- or no-cost vaccinations.

    Clients whose screening test results are positive for will need additional tests and examinationsusually with doctors who specialize in diseases of the liver to get accurate diagnoses and to determine their health status and the extent of liver damage. These tests are described in .

    Who Should Get A Hepatitis C Screening

    If youre under 18, you may or may not need a parents or guardians consent to get tested. State laws on minor consent for medical care vary. If youve been exposed to hepatitis C or feel that you need a test for any reason, dont let your age stop you from getting the medical help you need.

    If left untreated, hepatitis C can have serious consequences for your health. If you test positive, you can also pass the virus onto others.

    The recommends universal hepatitis C screening for:

    • all adults aged 18 and over
    • pregnant people

    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.

    How Is A Person Tested For Hepatitis C

    A viral-load test is used to check for hepatitis C in the bloodstream. Usually, hepatitis C virus can be found in a persons bloodstream two weeks after he or she becomes infected.

    *Except in case of recent risk or in people with a weakened immune system**During the first six months after HCV infection, a person may spontaneously clear the virus if there was a recent risk, repeat viral-load testing to confirm chronic hepatitis C infection

    Who Is Most At Risk Of Contracting Hepatitis C

    You have a high risk of contracting hepatitis C if you:

    • use or have used injection drugs even if it was just once or many years ago
    • have received blood or blood products or an organ transplant before July 1990 in Canada
    • have been in jail or
    • have been injected or scratched during vaccination, surgery, blood transfusion or a religious/ceremonial ritual in regions where hepatitis C is common.

    You have a high moderate risk of contracting hepatitis C if you:

    • have tattoos or body piercing
    • have multiple sexual partners
    • have a sexually transmitted infection , including HIV or lymphogranuloma venereum
    • have experienced traumatic sex or rough sex or have used sex toys or fisting that can tear body tissue
    • have vaginal sex during menstruation
    • have received a kidney treatment
    • have received an accidental injury from a needle or syringe
    • have another infectious disease
    • were born to a hepatitis C infected mother or
    • have a sexual partner infected with hepatitis C.

    Hepatitis C is NOT passed from person to person by:

    • coughing, sneezing
    • breastfeeding unless your nipples are cracked and bleeding or
    • oral sex, unless blood is present.

    Hcv Core Antigen Testing

    The hepatitis C core antigen is a viral protein. Since the core antigen is part of hepatitis C virus, it can usually be found in the bloodstream two weeks after infection.

    Since HCV core antigen testing is simpler and less expensive than viral-load testing, some experts suggest using it in resource-limited settings. Core antigen testing can be usedoften with HCV antibody testingto detect acute HCV or to confirm chronic HCV infection. HCV core antigen testing can also be used to measure treatment outcome. Although it does not detect low levels of HCV , usually the hepatitis C viral load is much higher in people who relapse after HCV treatment.

    Getting Tested Is The Only Way To Know If You Have Hepatitis

    There is a cure for hepatitis C

    A blood test called a hepatitis C antibody test can tell if you have been infected with the hepatitis C virus either recently or in the past. If you have a positive antibody test, another blood test is needed to tell if you are still infected or if you were infected in the past and cleared the virus on your own.

    Rna Or Viral Load Test

    If you test positively for hepatitis C antibodies, you will need to get a RNA or viral load test. The RNA test is a blood test that checks to see if hepatitis C is active in your body.

    • Negative
      • If your RNA test result is negative, you do not have hepatitis C.
    • Positive
      • If your RNA test result is positive, you may have chronic hepatitis C. Talk to your doctor right away about a treatment plan.

    Explanation Of Test Results:

    If this test result is positive, it means your body was exposed to the hepatitis C virus and made antibodies . However, it does not tell you whether you are still infected with hepatitis C. If the antibody test result is positive, you should be tested for hepatitis C RNA , which determines whether you are chronically infected. The lab will perform this RNA test automatically if your hepatitis C antibody test is positive.

    If the antibody test result is negative, it means you have not been infected with the hepatitis C virus, and further testing for hepatitis C usually is not needed.

    Question 7 What Proportion Of Hcv Antibody

    Among specimens with reactive HCV antibody results, approximately 52% have detectable HCV RNA at a level of > 15 IU/mL on reflex testing. However, the frequency varies markedly based on the strength of the signal of the antibody test, or signal-to-cutoff ratio. Specimens with an S/C ratio of at least 1.0 are considered reactive for HCV antibody7 and thus undergo reflex testing for HCV RNA. Analysis of approximately 200,000 specimens submitted to Quest Diagnostics for HCV antibody testing with reflex to HCV RNA testing demonstrate that the frequency of positive reflex results increases with increasing S/C ratio:

    Question 10 I Am Treating My Hcv

    Figure 2

    If HCV RNA is detectable at week 4 of treatment, per AASLD guidelines, it is suggested to repeat quantitative HCV RNA viral load testing after 2 additional weeks of treatment. If quantitative HCV RNA testing at week 6 of treatment shows an increase of greater than 10-fold , discontinuation of HCV treatment is recommended. The cause of a positive HCV RNA test result at week 4, with decreasing levels at week 6 or week 8, is unknown. There is no recommendation to stop therapy or extend therapy for these patients.9
