What Foods Should I Avoid
Everyone should avoid eating a lot of fat, cholesterol, salt and processed sugar, even if their liver is healthy. In addition, those with HCV should limit or avoid alcohol. Drinking alcohol will speed up liver damage.
Eating properly can help decrease some of the symptoms of Hepatitis C, like feeling tired and sick. Drink lots of water for general health benefits. HCV is not a digestive disease diet will not affect the disease. Your provider may put you on a special diet if you have advanced liver disease.
Natural History Following Infection With Hcv
Hepatitis C can present as acute or chronic hepatitis. Most of the cases of acute hepatitis C are asymptomatic. Symptomatic acute hepatitis with jaundice is seen in 10-15% of patients only and can be severe, but fulminant liver failure is rare. Spontaneous clearance is observed in 25-50% of those with symptomatic infection and in 10-15% of those with asymptomatic infection. The natural history following exposure to HCV is summarized in Figure 1.
Natural history following infection with hepatitis C virus
Chronic hepatitis C is marked by the persistence of HCV RNA in the blood for at least 6 months after the onset of acute infection. The risk of progression to chronic infection by HCV is influenced by various factors including:
- Age at the time of infection
- Coinfection with human immunodeficiency virus , HBV
- Concomitant alcohol consumption
- Comorbid conditions like cancer, immunosuppression, insulin resistance, nonalcoholic steatohepatitis, obesity, etc.
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.

How Do Screening Tests Work
Screening tests, often called HCV antibody tests , are used to determine if someone has ever been infected with the hepatitis C virus and look for antibodies to the hepatitis C virus in the blood. Antibodies are chemicals released into the bloodstream when someone gets infected.
Screening tests are important as they can help test more people quickly to help people know their status. With their ease of use and quick results, they offer health care providers a way to test more patients and help connect them to care and treatment quickly, including confirmatory HCV RNA tests.
It is important to note that HCV antibody tests are screening tests only and that all positive results will require a follow-up confirmatory HCV RNA test .
Hepatitis C Can Be Prevented
Although there is no vaccine to prevent hepatitis C, there are ways to reduce the risk of becoming infected.
- Avoid sharing or reusing needles, syringes, or any other equipment used to prepare and inject drugs, steroids, hormones, or other substances.
- Do not use personal items that may have come into contact with an infected persons blood, even in amounts too small to see, such as glucose monitors, razors, nail clippers, or toothbrushes.
- Do not get tattoos or body piercings from an unlicensed facility or in an informal setting.

How Do You Get Hepatitis C
Hepatitis C is a blood-borne illness, meaning it is transmitted via contact with infected blood. Usually the virus enters the body through a puncture wound on the skin. The most common way hepatitis C is transmitted is via injection drug use. Sharing dirty needles with someone who is infected can transmit hepatitis C. Health care professionals may contract the virus via needlestick injury. Prior to 1992, the U.S. blood supply was not screened the way it is today, so some people contracted hepatitis C from infected blood transfusions. Rarely, babies born to hepatitis C-infected mothers acquire the virus. Hepatitis C can also be spread by having sex with an infected person or sharing personal items with someone who has the virus, but these cases are rare.
What Does High/low Viral Load Mean
Viral load is the amount of virus present in the bloodstream. It is expressed as the amount of viral genetic material per milliliter of blood. The amount of virus does not predict how severe the liver disease is or will become. The level of the viral load does not tell us anything about the risk of liver damage or how sick someone is. In hepatitis C, it matters if virus is present or absent. Some treatment regimens can be shortened if the patient has a low viral load to start with, but most often, treatment regimens are the same for people with high hepatitis C viral loads or low viral loads.
The RNA test is essential for making the diagnosis of hepatitis C infectionhaving a positive RNA test is the definition of having infection. After the diagnosis is made, the RNA level does not need to be checked over and over unless it is checked during the time that the patient is undergoing treatment. During treatment, regular RNA tests are done to follow the dropping virus level until it reaches an undetectable state. But before treatment and after treatment, repeated RNA testing is not necessary.

Who Self Testing Guidelines
Recently, the WHO has released recommendations on HCV self-testing as an additional approach to hepatitis C testing services. As part of its goal to eliminate HCV as a public health threat by 2030 in its Global health sector strategy on viral hepatitis, the WHO aims to diagnose 90% of those with HCV and treat 80% of those diagnosed. To help reach this target, they have released guidelines considering HCV self-testing to help increase access to testing and, thus, treatment.
Screening For Hcv Infection
HCV screening has several potential benefits. By detecting HCV infection early, antiviral treatment can be offered earlier in the course of the disease which is more effective than starting at a later stage. Further, early detection together with counseling and lifestyle modifications may reduce the risk of transmission of HCV infection to other people. The optimal approach to screen for HCV is to test the individuals having risk factors for exposure to the virus. The American Association for the Study of Liver Diseases recommends screening for HCV for the following individuals:
- Recipient of blood or blood components .
- Recipient of blood from a HCV-positive donor.
- Injection drug user .
- Persons with following associated conditions
- persons with HIV infection,
- persons who have ever been on hemodialysis, and
- persons with unexplained abnormal aminotransferase levels.
- Children born to HCV-infected mothers.
- Healthcare workers after a needle stick injury or mucosal exposure to HCV-positive blood.
- Current sexual partners of HCV-infected persons.

Results Of The Hbcab Test
There are two variations of antibodies. The IgM antibody is the largest antibody and the first produced in an infection. It shows that you may have a current, active infection. Sometimes it persists for years, but it usually drops to undetectable levels.
The HBcAb IgG variant is produced later in the course of the infection, and its likely that you will have a positive HBcAb IgG test the rest of your life.
The screening panel usually has a test that is for total HBcAb, which includes both IgM and IgG. The IgM test may be ordered to help determine if you have an acute infection.
A positive HBcAb test must be interpreted along with the results of the other tests. You may have an active or chronic infection, or you may be immune to hepatitis B due to past infection. Discuss the results with your healthcare provider. In any case, a positive HBcAb test means your blood or organs cannot be donated to a recipient.
What Is A Biopsy
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.

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:

Test Notes It should be noted that the assay performance characteristics of the Hepatitis B Surface Antigen assay have not been established for either immunocompromised, immunosuppressed patients or on cord blood, neonatal sepecimens, infants, or children less than 12 years age.
How Do I Get Tested For Hep C
Finding out whether you have hep C starts with getting tested for HCV. This involves a blood test called an HCV antibody test.
You can ask to be tested at your primary care doctors office or a public health clinic, or you can test yourself using a home testing kit.
To find a clinic with HCV testing near you, visit the CDCs GetTested website and enter your zip code. This tool will help you find testing or free testing in nearby locations.
At-home test kits usually cost $50 to $100 for one test, which comes with all the materials and instructions you need. Youll collect a small amount of blood and send it off to a lab for testing.
Test results may seem intimidating, especially if they can be a little more complicated than just positive or negative. With HCV testing, the antibody test determines whether you have ever contracted HCV.
Breaking down test results:
- A non-reactive HCV antibody test result means you do not currently have HCV.
- A reactive HCV antibody test result means you currently have HCV or had it at some point, and the antibodies are in your blood.
So, if you dont have any HCV antibodies, you are negative for HCV.
If you do have HCV antibodies, that means youve either had it before or currently have it. If youve had it once, youll always have antibodies for it, whether your treatment has cleared it or not.

What Does Hepatitis B Core Igm Mean
IgM antibody to hepatitis B core antigen : Positivity indicates recent infection with hepatitis B virus . Its presence indicates acute infection. Tests.
What does it mean to be non immune to Hep B?
Answer. This means that you are susceptible hepatitis B. Often these words are used when the blood tests for hepatitis B do not show reactive, or levels of, hepatitis B surface antibody .
What does non reactive hepatitis B test results mean?
If your test results for hepatitis B came back as Non-reactive that is actually very good news. It means that you have never been exposed to the Hepatitis B virus, so you do not have the virus.
Risk Of Hcv Infection In Recipients Of Blood Transfusion
Prior to 1992, blood transfusions carried a high risk of HCV infection, approximately 15-20% with each unit transfused. In 1988, 90% of cases of posttransfusion hepatitis were due to NANBH viruses which was later found out to be due to HCV. The move to all-volunteer blood donors instead of paid donors had significantly reduced the risk of posttransfusion hepatitis to 10%. Screening of blood further reduced the rate of posttransfusion hepatitis C by a factor of about 10,000 to a current rate of 1 per million transfusions. The few cases that still occur are due to newly infected people donating blood before they have developed antibodies to the virus, which can take up to 6-8 weeks.

Are Test Results Accurate
Although no test is perfect, hepatitis C testing is an important and accepted method of testing for HCV. In order to reduce the risk of inaccurate results, doctors take steps to verify a patients diagnosis. For example, a positive test result for hepatitis C antibody requires confirmation with HCV RNA testing.

Are There Side Effects For The Treatment Using Daas
As with all medications, DAAs can cause side effects, though most are mild and become easier to tolerate as the treatment progresses. However, there are occasions when the treatment side effects are severe enough to stop treatment, though this is rarer.
Some of the side effects include but are not limited to:
- Fatigue and weakness
- Nausea and loss of appetite
- Sleep problems or insomnia
- Joint pain and muscle aches
The Hepatitis C Testing Process
In the case of a suspected new infection, two test results are usually required to confirm if someone currently has hepatitis C.
The first test is a screening test, which is an antibody test. This test detects antibodies in the blood to determine if a person has ever had a hepatitis C infection.
- A non-reactive screening test result indicates that the person does not have hepatitis C antibodies and has never had a hepatitis C infection. No further testing is usually performed.
- If the antibody test is reactive , this means that the person has antibodies to hepatitis C and therefore has had a hepatitis C infection at some point in their life.
The antibody test alone cannot tell whether the person has a current hepatitis C infection. A person will test positive for hepatitis C antibodies if they have hepatitis C at present, but also if they had a hepatitis C infection in the past. In other words, people will still have hepatitis C antibodies even if they spontaneously cleared the virus in the past or if they were treated and cured.
The second test is a confirmatory test, which detects the hepatitis C virus itself. This test detects genetic material of the virus to determine if a person currently has a hepatitis C infection.
If a person has had a positive antibody test result in the past, they will test positive for hepatitis C antibodies every time they have another screening or antibody test.

At-home screening tests provide privacy if you prefer not to go to a doctor or clinic for testing. These tests typically look for antibodies to hepatitis C, but they may not always test for active viral infection. Make sure you know what type of test youll be taking before you buy.
Many at-home tests have close to or the same reliability as blood tests received by a medical professional.
If youve recently been exposed to hepatitis C, wait several weeks before testing at home.
Did You Know Only 21% Of People Know They Have Hcv How Testing Plays A Role In Ending Hepatitis C
Hepatitis C is a viral infection in the liver caused by the hepatitis C virus, or HCV. It is spread through contact with blood from an infected person. Today, most people become infected with the virus by sharing needles or through equipment used to prepare or inject drugs. However, it can also be spread through birth from an infected mother to child, through sexual contact, sharing personal items contaminated with blood such as razors and toothbrushes, unregulated tattooing, and some health care procedures such as injections, infected blood transfusions , and needlestick injuries in healthcare settings.
The immediate period following infection is called the acute phase and lasts approximately six months. Many people do not experience symptoms during this phase, or if they do, they show non-specific symptoms such as fatigue, loss of appetite, and depression.
After six months, approximately 70%-85% of those infected with HCV will fail to clear the virus on their own, or spontaneously, and this is when hepatitis C becomes a chronic or long-term infection. This high rate showcases the importance of regular testing so that treatment, which is highly effective, can start right away.
