How Can I Tell If I Am Contagious And Can Spread The Infection To Others
If you have detectable HCV RNA in your blood, you have the potential to spread the disease to other people. Hepatitis C is spread by exposure to contaminated blood. The most common mechanism of exposure is the sharing of needles or other ‘works’ used in consuming drugs such as cocaine or heroin. Other routes of transmission include use of contaminated equipment for body piercing and tattooing, occupational exposure of healthcare workers to used needles or other sharp objects, and, less commonly, through sexual activity that results in tissue tears or from mother to baby during childbirth.
When Should I Get An Acute Viral Hepatitis Panel
An acute viral hepatitis panel may be recommended when a patient has symptoms of hepatitis, or if a person has a suspected or known exposure to a hepatitis virus. Although some patients with hepatitis have no symptoms, when present symptoms may include:
- Fever
- Clay-colored bowel movements
- Jaundice
Patients that have an acute hepatitis infection may begin to experience symptoms between 2 weeks and 6 months after becoming infected. Patients with a chronic hepatitis infection may not experience symptoms until many years after infection.
Doctors may also recommend an acute viral hepatitis panel in patients with abnormal results on tests that evaluate liver function, such as a liver panel.
How To Get Tested
An acute viral hepatitis panel is performed after being prescribed by a doctor. This panel of tests requires one sample of blood, on which multiple tests can be conducted.
A blood sample can be taken in a hospital, lab, or other medical setting. Blood can be drawn from a vein or, in children, blood can be obtained by pricking the skin. After collection, the blood sample is sent to a laboratory for analysis.

When To Get Tested
When you have risk factors for HBV infection or when you have signs and symptoms of hepatitis, such as jaundice or unexplained elevated blood levels of alanine aminotransferase , a liver-associated enzyme when you have a condition that requires chemotherapy or drugs that suppress your immune system when you are being treated for HBV or hepatitis C when it is unclear whether you have immunity and your healthcare practitioner is considering giving you the hepatitis B vaccine
What Is Being Tested
Hepatitis B is an infection of the liver caused by the hepatitis B virus . Hepatitis B blood tests detect viral proteins , the antibodies that are produced in response to an infection, or detect or evaluate the genetic material of the virus. The pattern of test results can identify a person who has a current active infection, was exposed to HBV in the past, or has immunity as a result of vaccination.
For details on the various tests, see the table under Common Questions: How is it used?
Hepatitis is a condition characterized by inflammation and, sometimes, enlargement of the liver. It has various causes, one of which is infection by a virus. HBV is one of five “hepatitis viruses” identified so far that are known to mainly infect the liver. The other four are hepatitis A, hepatitis C, hepatitis D, and hepatitis E.
HBV is spread through contact with blood or other body fluids from an infected person. Exposure can occur, for example, through sharing of needles for IV drug use or through unprotected sex. People who live in or travel to areas of the world where hepatitis B is prevalent are at a greater risk. Mothers who are infected can pass the infection to their babies, usually during or after birth. The virus is not spread through casual contact such as holding hands, coughing or sneezing. However, the virus can survive outside the body for up to seven days, including in dried blood, and can be passed by sharing items such as razors or toothbrushes with an infected person.

Medicare Part A Costs
In-hospital blood work ordered by your doctor is generally fully covered under Medicare Part A. However, you still need to meet your deductible.
In 2021, the Part A deductible is $1,484 for most beneficiaries during the benefit period. The benefit period lasts from the day you enter the hospital through the next 60 days. It is possible to have multiple benefit periods in a year.
Which Parts Of Medicare Cover Blood Tests
Medicare Part A offers coverage for medically necessary blood tests. Tests can be ordered by a physician for inpatient hospital, skilled nursing, hospice, home health, and other related covered services.
Medicare Part B covers outpatient blood tests ordered by a physician with a medically necessary diagnosis based on Medicare coverage guidelines. Examples would be screening blood tests to diagnose or manage a condition.
Medicare Advantage, or Part C, plans also cover blood tests. These plans may also cover additional tests not covered by original Medicare . Each Medicare Advantage plan offers different benefits, so check with your plan about specific blood tests. Also consider going to in-network doctors and labs to get the maximum benefits.
Medicare Part D provides prescription drug coverage and does not cover any blood tests.

The HCV antibody test may be performed as part of an acute viral hepatitis panel to determine which of the most common hepatitis viruses is causing your symptoms.
How Can I Save Money
Buying a test online and having your blood drawn at a locally approved lab can often be the cheapest option. Compare two to three accredited labs online see what these labs have to offer and how much you can spend. Most will list their prices on their pricing page.
Bundling your titer test with other tests can bring the costs down by more than 50 percent. If you know you want to be tested for more than one disease, this may be the most cost-effective method.
If youre a college student, check with your schools health center to see if the tests are offered at a discount.
According to some, your school insurance, if you have a policy through your college, may cover a portion or even the entire bill.

What Types Of Common Blood Tests Are Covered
Original Medicare and Medicare Advantage plans cover many types of screening and diagnostic blood tests. There may be limits on how frequently Medicare will cover certain tests.
You can appeal a coverage decision if you or your doctor believe a test should be covered. Certain screening blood tests, like those for heart disease, are fully covered with no coinsurance or deductibles.
Examples of covered blood tests
Here are some of the conditions that are commonly screened through blood tests and how often you can have them done with Medicare coverage:
- Diabetes: once a year, or up to twice per year if you are higher risk
- Heart disease: cholesterol, lipids, and triglycerides screening once every 5 years
- HIV: once a year based on risk
- Hepatitis : once a year depending on risk
- Sexually transmitted diseases: once a year
If your doctor thinks you need more frequent testing for certain diagnostic tests due to your specific risk factors, you may have to pay for testing more often. Ask your doctor and the lab for more information about your specific test.
It might be helpful to have a supplemental plan for more frequent testing. You can go to the Medicare Medigap policy website for information on all the plans for 2021 and whats covered. You can also call the plan directly for more information.
Examples of covered tests include:
| Condition |

Should I Get The Hbv Vaccine
The Centers for Disease Control and Prevention recommends that adults in high-risk groups get vaccinated. Some of these groups include people:
- In close contact with someone who has hepatitis B
- Who undergo dialysis
- With chronic liver or kidney disease
- With HIV or who seek treatment for other sexually transmitted diseases or drug treatment
- Who travel to countries where hepatitis B is common
- Who are healthcare workers with potential exposure to HBV
Unless there is something in your medical history to the contrary, it is prudent to get the series of vaccinations. Babies, children and adolescents are routinely given the series of shots if you have already been vaccinated, you probably are protected for many years, perhaps for life, and will not usually need to get the vaccine again.

Are Test Results Accurate
Although an acute viral hepatitis panel is a standard panel used to detect evidence of viral hepatitis, in many cases it provides only preliminary results. For patients who have abnormal results on the hepatitis B or C portions of this panel, additional testing is necessary to confirm the diagnosis.
When Is It Ordered
Hepatitis B tests may be ordered when someone has signs and symptoms associated with acute hepatitis to determine if they are due to infection with HBV. Some of these include:
- Fever
- Joint pain
- Jaundice
Hepatitis B tests may be done as follow up when routine tests results such as ALT and/or AST are elevated. Sometimes acute forms of hepatitis may be detected this way since they may cause only mild symptoms that can be confused with the flu. Chronic hepatitis more often has no symptoms and is more commonly detected when routine test results are abnormal.
A test for hepatitis B surface antigen may be used for screening when someone falls into one of the high-risk categories for chronic hepatitis B. Joint guidelines from the Centers for Disease Control and Prevention and American College of Physicians were published in December 2017 and recommend the following groups be tested for HBsAg:
When hepatitis B tests are used to monitor people with chronic hepatitis B infections, they may be performed on a regular basis. Hepatitis B surface antigen and hepatitis B e antigen , often along with HBV DNA, are usually measured about every 6 months to a year since, in some people, HBeAg will go away on their own. In those who are being treated for chronic HBV, HBeAg and HBV DNA tests can be used to determine whether the treatment is successful.

What Does The Test Measure
An acute viral hepatitis panel includes several tests that measure antigens and antibodies. Antigens are foreign substances such as proteins of the virus itself, while antibodies are substances produced by the immune system in response to the viral infection.
An acute viral hepatitis panel tests for antigens and/or antibodies of hepatitis A, B, and C:

How Much Does A Titer Test Cost
A titer test is used to determine the number of antibodies in the body, and these special antibodies are produced by the immune system to protect you in case youre exposed to a disease. This test will be ordered to show an individual has had a vaccination for a disease or had the disease in the past. Commonly, if a vaccination is unavailable, a school and/or medical center may require this test to prove your immunity.
How Is Hepatitis B Treated
There is no specific treatment for acute hepatitis B infections. Symptoms are usually treated with supportive care. This usually involves making sure that you are getting plenty of rest and enough fluids and nutrition by eating and drinking small amounts several times a day.
Chronic forms of hepatitis B may be treated with antiviral medications such as interferon, entecavir, tenofovir, lamivudine, and adefovir. However, some antiviral drugs can have serious side effects and not all people need to be treated. Often, people with chronic hepatitis will be closely monitored to see if they develop cirrhosis or liver cancer. It is important to talk to your healthcare provider about your treatment options and the risks and benefits of those currently available.

Hepatitis B Panel Blood Test
The Hepatitis B Panel is a series of blood tests used to detect current or past infections with the Hepatitis B virus. It can also be used to verify the status of immunity to Hepatitis B. The three tests included in this panel are the Surface Antibody, Surface Antigen, and Core Antibody.
Hep B is a viral liver infection which is spread through exposure to infected blood or bodily fluids. It is the most common cause of acute viral Hepatitis. Hepatitis B infections often show no symptoms but when symptoms do occur they are often described as flu-like. Common symptoms include abdominal pain, fever, loss of appetite, nausea, joint pain, fatigue, jaundice, and dark colored urine. Chronic Hep B infections can cause serious health complications such as Cirrhosis and Liver Cancer.
To gain a comprehensive understanding of Hepatitis B, this three part panel covers many aspects regarding the timeline of a possible infection.
- The Hepatitis B Surface Antibody looks for clinical recovery or subsequent natural or vaccinated immunity to Hepatitis B. The results are quantitative.
- The Hepatitis B Surface Antigen is the earliest indicator of the presence of acute infection.
- The Hepatitis B Core Antibody is used in conjunction with the other Hepatitis B tests to assess the stage of Hepatitis B infection.
This panel is typically ordered by people who are experiencing symptoms, believe they may have been exposed to Hep B, or wish to determine their current state of immunity.

What Antibody Testing Does And Doesnt Reveal
Antibody testing can tell you whether your immune system made proteins to fight off the virus. As a result, these tests may have a role to play in safely returning Americans to work. Use of validated blood tests can help public health officials identify patterns of exposure to the virus in local populations, for example.
At this stage of the pandemic, though, no one knows for sure whether a positive antibody test means youre safe from future infection. The problem is we do not know what antibody titer is necessary in order to be protected, IDSA board member Tina Q. Tan, MD, professor of pediatrics at Northwest Universitys Feinberg School of Medicine noted during a recent media briefing. Titer refers to the concentration of antibodies in the blood.

We dont know what level makes someone safe or how long such protection may last, added IDSA board member John B. Lynch, III, MD, associate professor in the Division of Allergy and Infectious Diseases at the University of Washington. Is it weeks, is it months, is it years, is it forever?
Antibody testing could give consumers a false sense of security, she says. People might disregard protective measure like wearing a mask, washing their hands, or maintaining social distancing if they believe they have immunity.

Hepatitis A Vaccine And Travel
If youâre going to a country where hepatitis A is common and youâve never had the virus or the vaccine, start the vaccination process as soon as you can. It takes 2 to 4 weeks after the first dose for the vaccine to work, but even one shot a few days before you leave will give you some protection.
People who are allergic to something in the vaccine and children younger than 6 months might instead get a shot of immune globulin , which will protect against hepatitis A for up to 2 months.
