Does Viral Hepatitis Affect Women Differently Than Men
Yes, certain types of viral hepatitis affect women differently than men.
Hepatitis A affects women and men in similar ways.
Hepatitis B affects women differently than men:
- Birth control. Women with severe liver damage may not be able to use birth control.1 This is because a damaged liver may have problems breaking down estrogen.
- Pregnancy. The risk of passing hepatitis B to your baby during pregnancy is high. Hepatitis B raises your risk for pregnancy complications.2 Talk to your doctor about taking hepatitis B medicine to lower the risk of passing hepatitis B to your baby. Certain hepatitis B medicines are safe to take during pregnancy but are not recommended for everyone. Learn more about hepatitis B during pregnancy.
Hepatitis C affects women differently than men:

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.
Hcv Core Antigen Detection
During the past decade, several assays for the detection of the core antigen of HCV by ELISA or CLIA have been developed. These assays were envisioned as alternatives to NAT to be used in resource-limited settings, where molecular laboratory services are either not available or not widely utilized owing to cost issues. Since these assays are either ELISA or CLIA based, they are user friendly, require less technical expertise and are less expensive compared to molecular techniques. Evaluations in transfusion settings have shown that the HCVcore Ag assay detects HCV infection as effective as NAT, about 40-50 days earlier than the current third generation anti-HCV screening assays. HCV core antigen levels closely follow HCV RNA dynamics, and allow clinical monitoring of a patients therapy, independently of HCV genotype. The major limitation of the HCV core Ag assay is its lower sensitivity limiting its utility. A new generation CLIA based quantitative test with sensitivity comparable to that of end point PCR but less than that of real time RT-PCR has been reported.

Dried Blood Spot Testing
Dried Blood Spot testing uses drops of blood from the end of your finger. It doesnt use a needle and syringe and you can do it free of charge in the privacy of your home. Your details and the results are kept private. If your test result shows you have hep C, the people who give your results can help you access hep C treatment and cure.
Blood Transfusion Issues And Donor Counseling
Guidelines for donor notification for donors positive for transfusion transmissible infections are outlined in An Action Plan for Blood Safety by National AIDS Control Organization 2004. A blood donor is offered an option to know his TTI status at the time of registration for blood donation after due counseling and give consent for the same.
Notifying donors regarding a single positive screening test is fraught with the risk of causing undue anxiety and stress to a donor. If a screening test is positive, the blood unit should be immediately discarded. Presently there are no guidelines regarding confirming the test results before informing the donor. In case of samples with low S/CO and grey zone samples, a retesting of the donor samples using a different assay would be imperative before notifying the donor. There are clear cut guidelines regarding donor notification and referral for HIV positive blood donors with integrated counseling and testing centers available for the same. Donors who are positive for viral hepatitis markers have to be counseled by blood bank staff. An algorithm for donor counseling for HCV positive donors is outlined in Figure 2.

Hepatitis C Virus Hcv Antibody
The Hepatitis C antibody test is used to screen for hepatitis C infection. Hepatitis C is a virus that is highly contagious, spreading through contact with blood and other bodily fluids of an infected person. Hepatitis C causes the highest rate of deaths than any other infectious disease.
Test results may take 1-2 business days once the specimen is received at the laboratory.
How Does Hepatitis C Progress
When someone is first infected with hepatitis C, most likely they have no symptoms and are unaware. Occasionally people experience fatigue, loss of appetite, weakness or sometimes having a yellow color in their skin or eyes. Although having any symptoms at all is rare, if they do occur, they usually go away within a few weeks.
Around 15-25% of people who are infected will spontaneously fight off the virus on their own and they will not have a chronic hepatitis C infection and no long term damage occurs.
But around 75-85% of people will develop chronic infection. Most of the time, people with chronic hepatitis C have no symptoms at the time of infection and no symptoms for years or even decades of chronic infection. The virus will be with them until they are successfully treated with hepatitis C medications.
Around 10-20% of people with chronic infection will slowly have gradual damage in the liver over years and will eventually develop cirrhosis . This can take 20 years or more from the time of the initial infection.
Cirrhosis is the replacement of liver cells with permanent scar tissue. Cirrhosis can lead to problems such as bleeding from veins in the esophagus, fluid buildup in the belly, and damaged brain function.Approximately 15% of people with cirrhosis will develop liver cancer during their lifetime. Drinking excessively can double the chance of liver cancer in people infected with HCV.

Assay Dilutional Sensitivity With Dbs Samples
The dilutional sensitivity of the ARCHITECT Anti-HCV assay with DBS samples was evaluated using dilution series created from two randomly selected plasma samples with high S/CO values. The two plasma samples were diluted in parallel in negative plasma and negative whole blood with a dilution factor ranging from 10 to 1000. The DBS S/CO results were compared to those for each plasma sample at each dilution level .
Table 1 Dilution sensitivity for 6-mm and 12-mm DBS eluted in EB and AD, tested with the standard and modified sample volume ARCHITECT anti-HCV assay.
The sensitivity of the modified assay and on-market assay with DBS as a sample was 100% and 90.97%, respectively. Specificity of the DBS assay evaluated using whole blood from 104 anti-HCV negative samples was 100% for both assays . The mean DBS S/CO value was 0.11 for the modified and 0.032 for the on-market assay. Positive predictive value was 100% for both assays. Negative predictive value was lower for the on-market assay: 88.89% vs 100% for the modified assay. Receiver operating characteristic plots were very similar for both assays , with area under the ROC curve indicating a perfect assay.
Who Is More Likely To Get Hepatitis B
People are more likely to get hepatitis B if they are born to a mother who has hepatitis B. The virus can spread from mother to child during birth. For this reason, people are more likely to have hepatitis B if they
- were born in a part of the world where 2 percent or more of the population has hepatitis B infection
- were born in the United States, didnt receive the hepatitis B vaccine as an infant, and have parents who were born in an area where 8 percent or more of the population had hepatitis B infection
People are also more likely to have hepatitis B if they
- are infected with HIV, because hepatitis B and HIV spread in similar ways
- have lived with or had sex with someone who has hepatitis B
- have had more than one sex partner in the last 6 months or have a history of sexually transmitted disease
- are men who have sex with men
- are injection drug users
- work in a profession, such as health care, in which they have contact with blood, needles, or body fluids at work
- live or work in a care facility for people with developmental disabilities
- have been on kidney dialysis
- live or work in a prison
- had a blood transfusion or organ transplant before the mid-1980s
In the United States, hepatitis B spreads among adults mainly through contact with infected blood through the skin, such as during injection drug use, and through sexual contact.12

What Is The Difference Between Hepatitis B Surface Antibody And Antigen
An antigen is a substance that induces antibody production. Hepatitis B surface antigen is a protein on the surface of hepatitis B virus.
Hepatitis B surface antibodies are produced by the bodys immune system in response to HBsAg. The presence of adequate hepatitis B surface antibodies in the blood indicates protection against hepatitis B virus infection.
How Often Do I Need A Viral Load Test
Understanding the specifics of your viral load is important at the time of diagnosis. Once you begin treatment, follow-up testing will let your doctor know if the current treatment is effective.
Other than that, theres no need for repeat testing. This is because the viral load doesnt provide information about your symptoms or whether your liver is functioning properly. Other liver tests, such as a biopsy, can provide that information.
Certain groups are more vulnerable to contracting HCV. Among them are:
- people on dialysis
- children born to HCV-positive mothers
- anyone who may have had contact with the blood of someone with hepatitis C
The most common methods of HCV transmission are:
- sharing needles and syringes used for injecting drugs
- a mother with hepatitis C transferring HCV to her child during childbirth
Occasionally HCV is transmitted through:
- having sex with someone who has hepatitis C
- getting a tattoo in a place that doesnt have good infection control
- sharing personal care items, such as a razor or toothbrush, with someone who has hepatitis C
Hepatitis C cant be transmitted through:
- coughing or sneezing

Viral Load Testing After A Positive Antibody Test
It is very important to wait after possible exposure to have the antibody test. The Centers for Disease Control says that antibodies may show in the blood between 6-7 weeks after exposure. If the test is negative at that time, it should be repeated at 6 months as some people take a longer time to develop the antibody. The HCV/RNA by PCR test is definitive earlier after exposure if there is a need to know sooner.
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.

What Is Hepatitis C Test
Hepatitis C Test is a blood test that is used for the detection of the Hepatitis C virus. There are several types of Hepatitis C test that is used by doctors for the diagnosis of Hepatitis C. The varied Hepatitis C tests are
Hepatitis C Antibody Test : Hepatitis C antibody test is used by doctors to ascertain whether or not a person has been affected by the HCV at any point of his/her life by detecting Hepatitis C antibodies in the blood.
Hepatitis C RNA Qualitative Test : Also referred to as PCR test, this test screens for current infection of the virus.
Hepatitis C RNA Quantitative Test: As the name suggests it is a quantitative test and measures the amount of Hepatitis C virus in the body. The Hepatitis C RNA Quantitative Test is also referred to as viral load test.

How To Get Tested
Hepatitis C testing is performed by a doctor. Testing requires a blood sample, which can be collected in a hospital, lab, or other medical setting. Blood is often drawn from a vein in the arm or, in children, taken by pricking the skin. After blood is collected, the sample is sent to a laboratory for analysis.

Hepatitis C Antibody Blood Test
The Hepatitis C Abs test is the most commonly ordered screening for Hepatitis C infections. This test looks for antibodies that develop in response to an infection. These antibodies are usually detectable at 4-12 weeks or greater after exposure. Results for this test are quantitative and will indicate a reactive , nonreactive , or in some cases, equivocal result. Hepatitis C is a virus spread through contact with infected blood. Nearly 80% of Hepatitis C infections develop into chronic Hepatitis. The number of people worldwide with chronic Hepatitis C infections is around 150 million. Chronic Hepatitis C infections can lead to serious health complications such as Cirrhosis and Liver Cancer. Many HCV infections display no symptoms. When symptoms do occur, some of the most common include:
Fever Grey feces Jaundice
Hepatitis C can be spread in a variety of ways. Some of the most common include intravenous drug use, improperly cleaned or sterilized tattoo and piercing equipment, sexual contact, blood transfusions , and from an infected mother to her infant during birth. The Hepatitis C Abs test is most commonly ordered as routine screening. This test can be ordered by anyone who is concerned they have been exposed to the Hepatitis C virus regardless of whether they are experiencing symptoms or not. For a recent exposure, the Hepatitis C RNA PCR Quantitative test may be more accurate.Turnaround time for the Hepatitis C Abs test is usually 1 business day.
Appropriate Uses Of The Hcv Rna Test
There are 4 major reasons that HCV RNA tests are used:
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.
