How Is Liver Damage Assessed

What are Hepatitis C Antibodies

If you have hepatitis C, doctors can gauge the level of liver damage you’ve experienced. One useful diagnostic tool is called a hepatic function panel, a group of blood tests performed together that examine the levels of certain liver enzymes, bilirubin , and proteins circulating in the blood.

Higher-than-normal levels of the liver enzymes, indicate that your liver is damaged, possibly from cirrhosis or liver cancer.

Albumin may be low, and your total bilirubin levels may also be elevated.

Along with the hepatic function panel, your doctor may also order two other tests: one test to determine the levels of the liver enzyme gamma-glutamyl transpeptidase in your blood, and a prothrombin time test that measures how well your blood clots.

A liver biopsy, in which a liver tissue sample is removed with a thin needle inserted through your skin and into your liver, can provide more details about the amount of scarring and damage HCV has caused.

Your doctor may also order an imaging test, such as a computerized tomography scan, magnetic resonance imaging , or ultrasound, to see if your hepatitis C has caused liver cancer, a possible complication of hepatitis C.

Question 10 I Am Treating My Hcv

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

  • How Much Does The Test Cost

    The cost of hepatitis C testing depends on the tests that are performed, where the test is conducted, and a patients health insurance coverage. When testing is ordered by a doctor, patients with health insurance may find it helpful to discuss the cost of hepatitis C testing with their insurance company. In addition to the cost of testing, there may be other out-of-pocket costs such as copays and deductibles.

    For patients without health insurance, or for whom insurance doesnt cover the cost of testing, it may be helpful to discuss the cost of hepatitis C testing with a doctor or hospital administrator.

    At-home hepatitis C testing starts around $49. Some at-home kits test for multiple types of viral hepatitis at once, with the cost of these panels starting around $80.

    What Does A Reactive Hepatitis C Test Result Mean

    non-reactive or negative antibody test means that you are not currently infected with the Hepatitis C virus. However, if you think you might have been exposed to Hepatitis C in the last 6 months, you will need to be tested again. What does a reactive Hepatitis C Antibody Test result mean? A reactive

    Question 8 What Do The Following Hcv Rna Results Mean: < 15 Iu/ml Detected Or < 15 Iu/ml Not Detected

    Hepatitis B Blood Tests Explained

    The result < 15 IU/mL, Detected means that HCV RNA is detected, although at a level that is too low to be quantified. This result could indicate current active HCV infection if consistent with other clinical and laboratory data. NOTE: If this test is being performed for HCV diagnosis, then this < 15 IU/mL Detected result should be confirmed using a second sample from the patient.

    In contrast, the result < 15 IU/mL, Not Detected means that HCV RNA is not detected and there is no evidence of current active infection.

    Quest Diagnostics measures HCV RNA viral load with the Roche cobas® HCV methodology. This is a quantitative real-time PCR assay with a lower limit of quantification of 15 IU/mL the limit of detection is slightly lower, at 10 IU/mL to 13 IU/mL. If the viral load is just at or above this LOD, but less than 15 IU/mL, the assay can determine that HCV RNA is present but cannot provide a reliable quantitative result. In such cases, the qualitative result of < 15 IU/mL, Detected is provided.

    Are There Supplements That Are Bad For My Liver

    Taking too many vitamin and mineral supplements may do more harm than good to a damaged liver.

  • Avoid taking too much vitamin A.
  • Do not take protein or amino acid supplements.
  • Avoid iron supplements unless your doctor prescribes them. Excess iron can build up in the liver and speed up damage.
  • If you have cirrhosis and your liver is not working, you may have to avoid substances such as steroids, acetaminophen, birth control pills, cortisone, barbiturates, and many other drugs.
  • Detection Of Hcv Antigen

    3.3.1 EIA

    The HCV core antigen is present in the blood of infected individuals, probably in both complete virions and RNA-free core protein structures. Various HCV Ag assays indicate that the kinetics of HCV Ag are similar to those of HCV RNA in all phases of infection, and that the concentrations of HCV Ag and HCV RNA roughly correlate. It has been estimated that 1 pg of HCV core Ag is equivalent to approximately 40,000 IU using the currently available commercial test . HCV Ag testing can reduce the serological window and may also be used to monitor antiviral therapy in chronically infected patients. All HCV genotypes and subtypes can be detected with a lower detection limit of approximately 0.06 pg/mL, inferior to the HCV RNA assay of approximately 10 IU/mL. The HCV Ag test is appropriate for screening for acute HCV infections in blood or organ donors, and high risk groups and could also be used to monitor treatment, except for the end point, where a very sensitive technique is needed to show a sustained response. This test is not routinely available in Australia at present.

    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.

    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.

    This result though is very rare. For a test value from 1.10 IV or greater, the results indicate positive results for HSV-1, that is, the presence of IgG antibodies detected in HSV-1 glycoprotein G. This results may show a past or a current HSV-1 infection. In some blood test, clarity is not seen when testing for HSV.

    Discusses Physiology Pathophysiology And General Clinical Aspects As They Relate To A Laboratory Test

    Hepatitis C virus is recognized as the cause of most cases of posttransfusion hepatitis and is a significant cause of morbidity and mortality worldwide. In the United States, HCV infection is quite common, with an estimated 2.4 million chronic HCV carriers.

    Laboratory testing for HCV infection usually begins by screening for the presence of HCV antibodies in serum, using an FDA-approved screening test. Specimens that are repeatedly reactive by screening tests should be confirmed with HCV tests with higher specificity, such as direct detection of HCV RNA by reverse transcription-PCR or HCV-specific antibody confirmatory tests.

    HCV antibodies are usually not detectable during the first 2 months following infection, but they are usually detectable by the late convalescent stage of infection. These antibodies do not neutralize the virus and they do not provide immunity against this viral infection. Decrease in the HCV antibody level in serum may occur after resolution of infection.

    Current screening serologic tests to detect antibodies to HCV include enzyme immunoassay and chemiluminescence immunoassay . Despite the value of serologic tests to screen for HCV infection, several limitations of serologic testing exist:

    -There may be a long delay between exposure to the virus and the development of a detectable HCV antibody

    -False-reactive screening test result can occur

    -A reactive screening test result does not distinguish between past and present HCV infection

    What Is A Biopsy

    Esophageal varices

    A biopsy is a medical procedure. A tiny piece of liver is removed and examined to find out the extent of damage. It involves a large needle and local anesthetic, as well as some risk of bleeding. A pathologist looks at the piece of liver under microscopes to determine how much damage has occurred in the liver. This is a very useful test and used to be done very commonly. However, the procedure is done much less frequently than in the past. For most patients with hepatitis B and C, liver biopsy is not required. Today, other tests can be used to try to estimate the fibrosis in the liver.

    How Can I Cover Medication Costs

    New therapies called direct-acting antivirals are effective and can achieve cures of over 90%. 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.

    Talk with your healthcare provider about financial support that may be available.

Please consult your private health insurance or drug plan provider to see if your drug is covered.

    Publicly funded plansEach provincial and territorial government offers a drug benefit plan for eligible groups. Some are income-based universal programs. Most have specific programs for population groups that may require more enhanced coverage for high drug costs. These groups include seniors, recipients of social assistance, and individuals with diseases or conditions that are associated with high drug costs.

    If I Get Tested For Hepatitis C And The Result Is Positive Do I Need Any Other Tests To Be Sure

    When your provider wants to test you for hepatitis C, the first test you will have is the hepatitis C antibody . If this test is positive, it means you were infected with the hepatitis C virus at some point in the past. But this test alone is not enough. You will still need another test to confirm if you still have the hepatitis C virus in your system. About 1 out of 5 people who get infected with hepatitis C will be able get the rid of the virus on their own, without treatment, very early after their infection. So some people will have a positive antibody test, but a negative HCV RNA .

    So, the second test that your provider should request is called hepatitis C virus RNA or HCV RNA test. There are several different tests available to check the HCV RNA. What matters is that if the RNA test is positive, then you do have chronic hepatitis C virus infection. If the RNA test is negative, then you may need to have this test again to be sure. If these RNA tests are all negative, then you no longer have hepatitis C infection and do not have chronic hepatitis C.

    If your hepatitis C antibody test is positive, be sure that you get tested for hepatitis C RNA to find out whether the infection has become chronic or whether it has cleared. If the infection has become chronic, there are treatments your provider can prescribe to fight off the hepatitis C virus and keep your liver healthy.

    Iatrogenic Exposure And Postexposure Prophylaxis

    The potential of health care delivery to transmit HCV to healthcare worker is increasingly being recognized especially if infection control or disinfection practices are inadequate and contaminated equipment is shared among patients. The mechanisms of transmission in the healthcare setting are related to:

    • Improperly cleaned, disinfected, or sterilized equipment

    • Medication administration

    • Blood sampling

    The CDC in collaboration with healthcare infection control practices advisory committee has issued recommendations following occupational exposure to HCV. These recommendations emphasize that each institution should have its own policy regarding follow-up of personnel who sustain percutaneous or permucosal exposure to suspected HCV infected blood. They minimally recommend:

  • Baseline testing for anti-HCV in source.

  • Baseline and follow-up testing for anti-HCV and alanine aminotransferase levels in exposed at 6 months and 1 year postexposure.

  • Confirmation by NAT of all anti-HCV reactive results.

  • Education of workers about the risk for and prevention of blood-borne infections.

    How to hepatitis C Antibody test in Medical lab?

    When you receive a false-positive result, you may be unsure whether its a true false positive. Talk with your doctor about getting a second test, such as an RNA test, to confirm whether you have an infection.

    If your RNA test result is negative, you dont have a current HCV infection. In this scenario, no further steps need to be taken. If your RNA test result is positive, your doctor will advise you on treatment options and how to move forward.

    Keep in mind that false-negative results may happen, too. This often occurs in people who are in the early stages of infection and havent yet built up detectable antibodies.

    People with suppressed immune systems may also get a false negative because their immune systems arent working effectively enough to respond to the test.

    Staying Healthy With Hepatitis

    Not everyone needs treatment right away, but its important to be monitored regularly by an experienced doctor and discuss treatment options of the best way to keep you healthy.

    • Get vaccinated against Hepatitis A and Hepatitis B
    • Avoid alcohol and drugs
    • Eat a healthy & balanced diet. Include a lot of vegetables and fruits try to stay away from too much salt, sugar and fat.
    • Exercise regularly. Walking is one of the best exercises, and it helps to make you feel less tired.
    • Check with a health professional before taking any prescription pills, supplements, or over-the-counter medications.
    • Do not share razors, nail clippers, needles or other items that come in contact with blood with other people.

    Hepatitis C Viral Load / Hcv Rna Quantitative Testing

    Hepatitis C

    The viral load of hepatitis C refers to the amount of virus present in the bloodstream. The quantitative HCV RNA tests measure the amount of hepatitis C virus in the blood. The result will be an exact number, such as “1,215,422 IU/L.” Many people refer to the quantitative measurement as the hepatitis C “viral load.”

    Viral load tests are used to confirm active hepatitis C infection and are used during treatment to help determine response. If you have lower levels of virus in your blood when you start treatment, you may have a better chance of getting rid of the virus.

    Hep C Antibodies Do Not Prevent Re

    What does it mean, in any real terms? Well, in terms of my status as being cured, it means nothing at all, because we do believe, as a fact, that antibodies for hep C offer no protection and so have no real value. It is interesting to me, and that is only because of my interest in the science of why and how things work, and there is some science that points to diminished antibody presence over time, and is it the same with all treatments? We dont know, and no need to be concerned, unless you too have a mildly science and nerdy side like me.

    What Are The Tests For Hepatitis C

    G. Diagnosis

    There are two blood tests needed to diagnose hepatitis C:

    The antibody test–called HCV antibody, HCV Ab, or anti-HCV–is done first. If this test is positive, it means that you have been infected with hepatitis C at some point in the past. If your antibody test is negative, then you have never been infected with hepatitis C if you were infected within the past month or so, the test may not be accurate you may needed to be retested at a later date.

    However, a positive antibody test does not tell you if you still have hepatitis C. For that, you need to have a HCV RNA test, which determines whether the virus itself is in the bloodstream.

    If any RNA is present in the blood after 6 months from time of infection, then you have chronic hepatitis C.

    If no RNA is detected in the blood after 6 months, you no longer have hepatitis C.
