How Do You Read Hep B Titer Results
For hepatitis B surface antibody , a level less than 5 mIU is considered negative, while a level more than 12 mIU is considered protective. Any value between 5 and 12 mIU is indeterminate and should be repeated.
What does positive hepatitis A IgG mean?
A negative result indicates the absence of HAV-specific IgG antibody, implying no past exposure or immunity to HAV infection. A positive result indicates the presence of HAV-specific IgG antibody from either vaccination or past exposure to hepatitis A virus.
What is the treatment for HEPA B reactive?
Treatment for chronic hepatitis B may include: Antiviral medications. Several antiviral medications including entecavir , tenofovir , lamivudine , adefovir and telbivudine can help fight the virus and slow its ability to damage your liver.
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.

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.

Hepatitis B Surface Antibody Qualitative
Presence of antibody to hepatitis B surface antigen is used to determine immune status to HBV or disease progression in individuals infected with HBV. Anti-HBs levels can be measured to determine if vaccination is needed, or following a vaccination regimen, to determine if protective immunity has been achieved.
– Anti-HBs usually can be detected several weeks to several months after HBsAg is no longer found, and it may persist for many years or for life after acute infection has been resolved.
– It may disappear in some patients, with only antibody to core remaining.
– People with this antibody are not overtly infectious.
– Presence of the antibody without the presence of the antigen is evidence for immunity from reinfection, with virus of the same subtype.
What is the Hepatitis B virus?
Hepatitis B virus infection, also known as serum hepatitis, is endemic throughout the world. The infection is spread primarily through blood transfusion or percutaneous contact with infected blood products, such as sharing of needles among injection drug users. The virus is also found in virtually every type of human body fluid and has been known to be spread through oral and genital contact. HBV can be transmitted from mother to child during delivery through contact with blood and vaginal secretions, but it is not commonly transmitted via the transplacental route.
The incubation period for HBV infection averages 60 to 90 days .

What Are The Recommendations For Follow
Anti-viral agents or immune globulin should not be used for postexposure prophylaxis.
For the source, baseline testing for anti-HCV.
For the person exposed to an HCV-positive source, baseline and follow-up testing including baseline testing for anti-HCV and ALT activity and follow-up testing for anti-HCV and ALT activity.

What Are Normal Titer Levels
The normal values of an antibody titer depend on the type of antibody. If the testing is done to detect autoantibodies, the normal value should essentially be zero or negative. In the case of testing the efficacy of a vaccine, the normal test result depends on the definite value that is specific for that immunization.
What does it mean if your anti HBs test is negative?
However, the fact that the negative Anti-HBS result does not mean that the person is not suffering from hepatitis B and is not affected by infection. In order to understand this condition, the level of HBsAg known as Hepatitis B surface antigen test should be checked.
What doeshbsag non-reactivemean for hepatitis B?
A non-reactive result for hepatitis B surface antigens means that you dont have an infection. So, its negative. If it were positive or reactive, it would mean that you had an ongoing acute or chronic hepatitis B infection.
How Can I Make A Difference For People With Hepatitis C
Anyone can help raise awareness about this widespread disease. Citizens can write letters to their state representatives or local newspapers and get involved in volunteer efforts with liver disease or Veteran-affiliated organizations . Speaking at support groups and sharing your experience is also a good way to help others with HCV.

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.
Clinical Information Discusses Physiology Pathophysiology And General Clinical Aspects As They Relate To A Laboratory Test
Hepatitis B e antigen is a small polypeptide that exists in a free form in the serum of individuals during the early phase of hepatitis B infection, soon after hepatitis B surface antigen becomes detectable. Serum levels of both HBeAg and HBsAg rise rapidly during the period of viral replication. The presence of HBeAg in serum correlates with hepatitis B virus infectivity, the number of infectious virions, and the presence of HBV core antigen in the infected hepatocytes.
During recovery from acute hepatitis B, HBeAg level declines and becomes undetectable in the serum, while hepatitis B e antibody appears and becomes detectable in the serum. Anti-HBe usually remains detectable for many years after recovery from acute HBV infection.
In HBV carriers and patients with chronic hepatitis B, positive HBeAg results usually indicate presence of active HBV replication and high infectivity. A negative HBeAg result indicates very minimal or no HBV replication. Positive anti-HBe results usually indicate inactivity of the virus and low infectivity. Positive anti-HBe results in the presence of detectable HBV DNA in serum also indicate active viral replication in these patients.

Counseling Practices That Educate Support And Motivate Clients Undergoing Screening
Clients might need help deciding whether to get screened, understanding the test results, and determining their next steps. Even when services offered through the substance abuse treatment program are limited, discussing testing with clients presents an opportunity for counselors to motivate clients for change by confronting substance use and by making choices that improve their overall health. However, this may also be true when services are offered on-site through substance abuse treatment programs. A study at one methadone clinic that offered hepatitis screening and vaccination revealed that although the majority of clients completed screening , only 54.7 percent of clients who lacked for hepatitis A received vaccinations and only 2.9 percent of clients who lacked immunity for received vaccinations .
The Consensus Panel makes the following general recommendations while recognizing that, in some programs, the counselors role may be limited:
Understanding Your Test Results
Understanding your hepatitis B blood tests can be confusing. It is important to talk to your health care provider so you understand your test results and your hepatitis B status. Are you infected? Protected? Or at risk? The Hepatitis B Panel of blood tests includes 3 tests and all three results must be known in order to confirm your status.
Below is a chart with the most common explanation of the test results, but unusual test results can occur. Please note that this chart is not intended as medical advice, so be sure to talk to your health care provider for a full explanation and obtain a printed copy of your test results. In some cases, a person could be referred to a liver specialist for further evaluation.
More Detailed Information About Hepatitis B Blood Tests
An acute hepatitis B infection follows a relatively long incubation period – from 60 to 150 days with an average of 90 days. It can take up to six months, however, for a person to get rid of the hepatitis B virus. And it can take up to six months for a hepatitis B blood test to show whether as person has recovered from an acute infection or has become chronically infected .
The following graphic from the U.S. Centers for Disease Control and Prevention represents the typical course of an acute hepatitis B infection from first exposure to recovery.
According to the CDC, a hepatitis B blood test result varies depending on whether the infection is a new acute infection or a chronic infection.

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.

Getting Tested For Hepatitis C
A blood test, called an HCV antibody test, is used to find out if someone has ever been infected with the hepatitis C virus. The HCV antibody test, sometimes called the anti-HCV test, looks for antibodies to the hepatitis C virus in blood. Antibodies are chemicals released into the bloodstream when someone gets infected.
Test results can take anywhere from a few days to a few weeks to come back. Rapid anti-HCV tests are available in some health clinics and the results of these tests are available in 20 to 30 minutes.

What Is Hepatitis C
Hepatitis C is a virus that causes inflammation of the liver. It is a member of the family of viruses that includes hepatitis A and hepatitis B. These viruses behave differently and have different modes of transmission. Hepatitis C can cause serious liver damage, liver failure, liver cancer, and even death.
Explainer: Lab Results And Their Interpretation
Hi Everich, there are basically 3 blood tests that are required for a new vs. a chronic hepatitis B infection. Below is a simple summary of these tests. If you could let us know which blood test was indeterminate that would be very helpful.
Hepatitis B surface antigen – If or means the hep b virus is present. This could mean a new infection or a chronic infection . If this test is or , then the hep b virus is not present in the blood.
Hepatitis B surface antibody – this tests for a protective antibody against the hep b virus. This can occur through getting the hep b vaccine or recovery from an exposure to the virus. If or , then it means a person has been protected against the hep b virus either through vaccination or recovery from an infection. Generally, the above test will be or .
Hepatitis B core antibody – this tests for an exposure to the hep b virus. If it is then a person has been exposed the hep b virus. If it is then the person has not been exposed to the virus.
Everich, do any of these tests appear on your wifes results? Can you ask the doctors office for a copy of her blood test results if you dont have them? Thanks and we all look forward to helping answer your important question. Always, Joan

What is HBsAg test?
Hepatitis B. Hepatitis B is a serious liver infection caused by the hepatitis B virus .
What does HBsAg positive mean?
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.
Nat: Detection Of Hcv Rna
Molecular virological techniques play a key role in diagnosis and monitoring of treatment for HCV. Because it is difficult to cultivate the virus in cell culture, molecular techniques were instrumental in first identifying HCV, making it one of the first pathogens to be identified by purely molecular methods. NAT is considered the gold standard for detecting active HCV replication. HCV NAT is extremely useful in establishing the diagnosis of acute HCV infection, since RNA is detectable as early as 1 week after exposure via needle-stick or blood transfusion, and at least 4-6 weeks prior to seroconversion as demonstrated in a number of transmission settings. The diagnosis of HCV infection is established with antibody screening followed by NAT for HCV RNA for confirmation as well as for follow-up of patients on treatment. Viral load assessment at baseline is also critical for determining response kinetics during therapy. enumerates the role of NAT in HCV diagnosis.

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:
Identifying Patterns Of Risky Behavior
Screening is an opportunity to draw attention to the clients behaviors that put him or her at risk for contracting :
- Ask for the clients perception of his or her risk for having contracted : How likely do you think it is that the test will be positive?
- Listen for and identify behaviors that put the client at risk for contracting , B, and C and HIV, especially unprotected sex and sharing injection drug paraphernalia.
- Assess the clients alcohol consumption.

Recommended Laboratory Evaluation Prior To Referral
All persons referred for further evaluation and management of HCV infection should have a confirmed positive HCV RNA level, preferably a quantitative HCV RNA level and not a qualitative HCV RNA level. It is ideal, but not imperative, that the clinician who makes the diagnosis of HCV infection can perform some preliminary tests to provide advanced information in anticipation of the initial referral visit. These initial preliminary tests include an HCV genotype, tests of synthetic liver function , hepatic inflammation , and assays to detect relevant coinfection . For primary care providers taking on a more comprehensive role for the initial evaluation and management, see Module 2, Lesson 1 for a detailed discussion in the Core Concept Initial Evaluation of Persons with Chronic Hepatitis C.
