Do You Have To Fast For Hepatitis C Blood Test

All Adults Pregnant Women And People With Risk Factors Should Get Tested For Hepatitis C

Get Tested for Hepatitis C

Most people who get infected with hepatitis C virus develop a chronic, or lifelong, infection. Left untreated, chronic hepatitis C can cause serious health problems, including liver damage, cirrhosis, liver cancer, and even death. People can live without symptoms or feeling sick, so testing is the only way to know if you have hepatitis C. Getting tested is important to find out if you are infected so you can get lifesaving treatment that can cure hepatitis C.

Implications For Service Providers

Point-of-care testing for hepatitis C antibodies and RNA is highly accurate and could increase testing uptake. Point-of-care testing can be particularly useful among communities with a higher prevalence of hepatitis C, such as people who use drugs, or people living in remote settings. Point-of-care testing can increase access to testing and simplify the process by enabling providers to conduct the testing and share the results at the same appointment. It also allows for hepatitis C testing in non-traditional settings where people are already accessing services such as harm reduction services, services that support people experiencing homelessness such as shelters or drop-in programs, and mobile services, as well as during outreach.

Service providers will need to consider whether they have access to point-of-care tests and how these test results are integrated into the public health and medical systems. Service providers can consider advocating for public funding of point-of-care testing in their regions and for novel ways to disseminate the tests, to help expand access to testing. Service providers can also consider whether advocating for acceptance of point-of-care test results by the public health and medical systems may be needed to truly simplify the cascade of care and realize the full benefits of point-of-care testing.

If You Have Hepatitis C Can You Have Sex Without Infecting Your Partner

Hepatitis C is a virus that is transmitted by blood. The most common ways people become infected with hepatitis C are through needle sharing, such as during injection drug use, or from blood transfusions received before 1992.

Becoming infected from sex is not common, but it does happen. If you have hepatitis C, the chance of infecting a sex partner is higher if you are with a new partner or if you have had many different partners over time. If you have hepatitis C, the chance of infecting a sex partner is lower if you are with a longtime stable partner and if you are in a monogamous relationship.

If your sex partner is new to you, or if you have many different partners, it is safer if you use condoms during sex to reduce the chance of transmitting hepatitis C.

It is always best to talk directly with your health care provider to assess whether you should start using condoms. If you are in a sexual relationship and either you or your partner has hepatitis C, the other partner should be tested for hepatitis C and other sexually transmitted viruses once a year, or as advised by your provider.

How The Test Works

The HCV antibody test requires a small blood sample. This sample is usually taken by a lab technician who draws a vial of blood from a vein in your arm. The actual blood draw usually takes less than a minute.

Your blood sample is then analyzed to see if antibodies for hepatitis C are present in your blood. Antibodies are Y-shaped proteins that your body creates to fight off pathogens.

Antibodies are specific to the virus or infection they are created to target, so if youve ever had hepatitis C, your body will have produced antibodies to fight it. If youve never had a hep C infection, those antibodies wont be present in your blood.

Results from the test can take anywhere from a few days to a week or two. Rapid tests for hepatitis C are also available if you need the results in an hour or less.

If your HCV antibody test comes back as reactive, it means that one of two things is true:

  • you have an active case of hepatitis COR
  • you have had hepatitis C at some point in the past

If you have hepatitis C, your body will have the ability to produce hepatitis C antibodies for the rest of your life. This is why a reactive result doesnt always mean that you have an active infection.

If your HCV antibody test comes back as nonreactive, it means two things are true:

  • you dont currently have hepatitis C AND
  • youve never had an active hepatitis C infection

Early Treatment Can Help You Prevent Liver Cancer Or Liver Failure

According to the CDC, out of every 100 people with hepatitis C:

  • More than half will develop chronic liver disease.
  • About 5 to 25 will get cirrhosis, a dangerous scarring of the liver.
  • 1-5 will die from liver cancer or liver failure.

Getting tested and treated early can stop the hepatitis C virus from triggering cirrhosis or cancer. Your doctor will be able to keep an eye out for signs of liver trouble. They can start treatment before you serious damage starts.

Now is the best time to test for hepatitis C. Know your sexual health status today.

If you have had a recent unprotected sexual encounter with someone whose hepatitis C status you do not know, youshould get tested. Also, if you have recently been exposed to needles or been injured by a sharp object, you are atrisk of contracting hepatitis C. Getting tested now is the best option to prevent acute hepatitis C from developinginto chronic hepatitis C. On average it takes the body about 8-9 weeks to create antibodies. This is the doctorrecommended period for hepatitis C testing.

Also if you have not been tested for other STDs like chlamydia, gonorrhea, syphilis, HIV-1, HIV-2, hepatitis A andB, herpes-1 or herpes-2, in the last year, our clinicians recommend taking the all-inclusive10 Test Panel to ensure that you are completely STD free.

We also offer a chlamydia-gonorrhea test panel. Chlamydia andgonorrhea are known as co-existing infections, meaning that having one infection may put you at risk of having theother.

Appropriate Uses Of The Hcv Rna Test

There are 4 major reasons that HCV RNA tests are used:

  • To confirm a positive HCV Ab result and make the diagnosis of current HCV infection
  • To measure a patient’s baseline viral load prior to starting HCV therapy
  • To monitor a patient’s response to therapy
  • To determine whether a patient has achieved a sustained virologic response
  • More rarely, HCV RNA is used when either very acute HCV infection is suspected or a false HCV Ab is suspected.

    It would not be appropriate to repeatedly order HCV RNA viral load screening for a patient who is not on or was recently on HCV treatment, or to use the HCV viral load to determine the severity of the patient’s infection or the patient’s risk of developing significant liver disease.

    What Are The Advantages Of Point

    Testing is a critical step to diagnose and link people with hepatitis C to care and treatment services and can also serve as an important part of prevention services and education. Compared with other types of testing, point-of-care testing has advantages that could reduce some barriers to hepatitis C testing. To achieve elimination of hepatitis C as a public health threat by 2030, advances in hepatitis C testing are required to simplify the hepatitis C cascade of care in Canada.7

    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.

    What kind of blood test is hepatitis panel?

    A hepatitis panel is a blood test that doctors use to diagnose hepatitis. Hepatitis refers to a group of viral liver diseases, including hepatitis A, hepatitis B, and hepatitis C. The blood test will typically include tests for three common types of hepatitis.

    Is it possible to get a negative result from a hepatitis panel?

    Negative result If the hepatitis panel does not identify any antigens or antibodies, then the person having the test is unlikely to have hepatitis. The main exception to this is if a doctor performs the blood test too early.

    Diagnosing Hepatitis A B & C

    At NYU Langone, hepatologists, or liver specialists, and infectious disease specialists use blood tests to diagnose hepatitis A, B, and C. These viral infections cause inflammation of the liver.

    If the results of a blood test confirm a diagnosis of viral hepatitis, your doctor may recommend imaging tests or a liver biopsy to determine the extent of liver disease.

    Tests After The Diagnosis

    Once the doctor knows you have hep C, theyâll do tests to find out more about your condition. This will help determine your treatment. They could include:

    • Genotype tests to find out which of the six kinds of hepatitis C you have.
    • Liver function tests. They measure proteins and enzymes levels, which usually rise 7 to 8 weeks after youâre infected. As your liver gets damaged, enzymes leak into your bloodstream. But you can have normal enzyme levels and still have hepatitis C.
    • Tests to check for liver damage. You might get:
    • Elastography. Doctors use a special ultrasound machine to feel how stiff your liver is.
    • Liver biopsy. The doctor inserts a needle into your liver to take a tiny piece to examine in the lab.
    • Imaging tests. These use various methods to take pictures or show images of your insides. They include:

    How Long Should I Fast Before Blood Test

    You are required to fast for up to 12 hours before going for a blood test. Drinking coffee, tea or even water can affect blood test results.

    Avoid Over Fasting, this particularly applies to diabetic individuals and pregnant women. Over fasting can cause dehydration and hypoglycemia in diabetics. Over fasting can also sometimes alter test results.

    Make sure to carry some snacks to your physicians office so that you can eat immediately after blood is drawn. Blood glucose for postprandial levels requires you to eat and give a blood sample after an hour of a meal.

    Hopefully, this article has given you a good idea about fasting for blood tests and which blood tests require fasting. These questions should additionally be clarified with your physician. This is because your physician will be able to guide you better.

    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.

    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.

    Time For Processing Hcv Ab Test Results

    At

    The turnaround time for 3rd-generation EIAs is at least 1 day. Many labs do not perform the tests on site and must send specimens to another lab for processing, which may further increase the turnaround time.

    A point-of-care test is also available. The OraQuick® HCV Rapid Antibody Test is an FDA-approved test that can be performed with a fingerstick . It is also a CLIA-waived test and therefore can be used in clinic offices and outreach facilities. Results are reported as reactive or nonreactive within 20 minutes. Just as for the standard HCV Ab test done in the lab, a positive OraQuick® test must be confirmed by an HCV RNA test. The sensitivity and specificity of the test is similar to that of the laboratory-based assays.
