Hepatitis C Non Reactive Means

Can I Take The Test At Home

what does hiv test non reactive mean ?

At-home hepatitis C tests are available that allow patients to collect a blood sample at home and mail it to a laboratory for testing. Test samples are collected through pricking a finger with a sharp object, called a lancet, thats included in the test kit.

At-home HCV testing is a form of hepatitis C antibody testing and does not test for hepatitis C RNA or the strains genotype. Testing for hepatitis C at home is not a substitute for testing performed by a health care professional, and positive test results may need to be confirmed by laboratory-based testing.

Question 2 For Whom Is Hcv Screening Recommended

The US Preventive Services Task Force and the CDC recommend 1-time screening for HCV infection for adults born 1945 through 1965.2,3 One-time screening is also recommended for adults with high risk due to:

  • Injection drug use 3,4
  • Receipt of transfusions or organ transplants prior to July 19923,4
  • Having ever received long-term hemodialysis3,4
  • Incarceration3
  • Receipt of clotting factor concentrates produced before 19873,4
  • HIV infection the co-infection rate among this group is 20% to 30%5

Screening is also recommended for children born to HCV-positive mothers.3,4

Individual Donar Nucleic Acid Testing

For ID-NAT, Procleix Ultrio kit was used based on TMA. The assay contains reagents which are used for simultaneous detection of all three viruses initially. Initial NAT assay was done on the pilot tube sample and if found reactive then the sample from the bag was repeated twice. The repeat sample testing if found reactive, was further tested by discriminatory testing for HBV, HCV, and HIV, respectively. A positive discriminatory test confirmed the presence of the respective virus. The clinical sensitivity for the Procleix Ultrio Assay has been demonstrated for specimens with HIV-1 or HCV viral RNA concentrations equal to or > 100 copies/ml or HBV viral DNA concentrations equal to or > 15 IU/ml.

Will The Baby Be Infected If The Mother Or Father Has Hepatitis C

The baby’s risk of becoming infected with hepatitis C in the womb varies, depending on whether the parent with hepatitis C is the father or the mother.

If the mother is infected, whether or not the father is infected, there is a 5% chance that the baby will be born with hepatitis C. The risk is the same regardless of whether the birth occurs by vaginal delivery or by cesarean section. The risk is higher if the mother is also living with HIV.

If the father has hepatitis C but the mother does not, the baby cannot become infected because a father cannot pass the virus directly to a baby. If the father first passes the virus to the mother through sex, then the baby possibly could be infected by the mother. However, the chance of the virus being transmitted both from father to mother and then from mother to baby is almost zero.

All children born to HCV-infected women should be tested for HCV infection. Testing is recommended using an antibody-based test at or after 18 months of age. Approximately 25-50 % infants with hepatitis C will clear the infection without any medical help by age 4. For those who become chronically infected, most have no symptoms .

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:

Can I Get Reinfected With Hepatitis C

If you become infected with hepatitis C infection and then clear the virus , yes, it is possible for you to become infected again.

The chance of another infection with hepatitis C is much, much less than the chance of a first-time infection, but it is not impossible. It has happened in people who continue to use injection drugs, and some studies suggest that it happens even more often in people who are also HIV positive.

In other words, having had hepatitis C once does not make you “immune” to getting hepatitis C again.

The best way to avoid reinfection is to reduce risky behaviors that can result in exposure to the hepatitis C virus: Do not use injection drugs, do not share needles for any reason, avoid blood-to-blood exposures with others, and use condoms if you are sexually active with a new partner or with a partner who has used injection drugs.

The research in this area is ongoing, and we will continue to learn more about this very important topic. But for now, preventing re-exposure to the hepatitis C virus is the only sure way of avoiding infection and reinfection with hepatitis C.

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 Does A Reactive Hepatitis C Antibody Test Mean

HBsAg Non Reactive Meaning l Non Reactive Test results l HBsAg Negative l Hepatitis B

A reactive hepatitis C antibody test means that the patient has hepatitis C antibodies in his blood. However, since a person who has cleared the hepatitis C virus still tests positive for antibodies, a follow-up test is required to determine if he is currently infected, says WebMD.

Hepatitis C is a liver infection caused by the hepatitis C virus. It is spread when blood from an infected person enters the blood stream of a healthy person. Infected people experience symptoms such as stomach pain, nausea, loss of appetite, fatigue, joint pain and jaundice. Some patients can live for years without any symptoms, which can lead to advanced liver disease due to delayed treatment. A hepatitis C antibody test is therefore the only sure determiner of a hepatitis C infection, says the

Centers for Disease Control and Prevention.

Other Things To Know:

  • If a patient has a quantitative test that shows no detectable virus, but has a positive result with the qualitative test, it means there is a very low level of virus that can be detected only with the qualitative test.
  • The qualitative test will become negative during hepatitis C treatment and indicates a good response.
  • A negative qualitative test 10-12 weeks after finishing hepatitis C treatment means you are cured.
  • The qualitative test result also will be negative if the patient clears the hepatitis C virus on their own, soon after infection, or “spontaneously.” If the result is still positive after 6 months, treatment should be considered.

False Reactive Test Results

What if I have a false reactive test result?

Every donation given to Canadian Blood Services is tested for infectious diseases caused by the hepatitis viruses B and C, HIV, syphilis and another uncommon virus called HTLV .

A false reactive test result means your initial screening test was reactivein other words, suggested the presence of something that would prevent you from donating bloodand a more precise follow-up test was negative. Almost all false reactive results occur because of interference with a test and are not necessarily due to testing positive for an infection.

FAQS

How does Canadian Blood Services test blood?

We follow a two-stage testing method that is used in laboratories worldwide. In the first stage, a sensitive screening test looks for the possible presence of infection. If the screening test shows no reaction, the blood is considered free of infection and no further testing is done. However, if the screening test is reactive, further testing is done to sort out whether the reactive result was due to an infection in the blood or interference with the test. The second test identifies markers in the blood that are found only when infection is present.

Do I need to go to my doctor for repeat testing?

Yes. Repeat testing should be discussed with your doctor because he/she is in the best position to offer you personal medical advice.

Do my partner, children, or friends need to worry if I’ve had a false reactive result?

Preparation Prior To Transport

Hepatitis B Blood Test (HBsAg)

Label the specimen container with the patients full name, date of collection and one other unique identifier such as the patients date of birth or Health Card Number. Failure to provide this information may result in rejection or testing delay.

Centrifuge if using SST. Place specimen in biohazard bag and seal. Specimens should be stored at 2-8°C following collection.

Specimens more than 7 days post collection will not be tested.

How Is Liver Damage Assessed

If you have hepatitis C, doctors can gauge the level of liver damage you’ve experienced. One useful diagnostic tool is called a hepatic function panel, a group of blood tests performed together that examine the levels of certain liver enzymes, bilirubin , and proteins circulating in the blood.

Higher-than-normal levels of the liver enzymes, indicate that your liver is damaged, possibly from cirrhosis or liver cancer.

Albumin may be low, and your total bilirubin levels may also be elevated.

Along with the hepatic function panel, your doctor may also order two other tests: one test to determine the levels of the liver enzyme gamma-glutamyl transpeptidase in your blood, and a prothrombin time test that measures how well your blood clots.

A liver biopsy, in which a liver tissue sample is removed with a thin needle inserted through your skin and into your liver, can provide more details about the amount of scarring and damage HCV has caused.

Your doctor may also order an imaging test, such as a computerized tomography scan, magnetic resonance imaging , or ultrasound, to see if your hepatitis C has caused liver cancer, a possible complication of hepatitis C.

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.

Rna Or Viral Load Test

If you test positively for hepatitis C antibodies, you will need to get a RNA or viral load test. The RNA test is a blood test that checks to see if hepatitis C is active in your body.

  • Negative
    • If your RNA test result is negative, you do not have hepatitis C.
  • Positive
    • If your RNA test result is positive, you may have chronic hepatitis C. Talk to your doctor right away about a treatment plan.

What Is The Difference Between Relapse And Nonresponse

hepatitis B e Antigen ( HBeAg) test in hindi | hbeag negative means | hbeag positive means

The goal of treating chronic hepatitis C is to completely clear the virus. This means that your “viral load” is zero or so low that the virus can’t be detected with standard blood tests.

Without treatment, the hepatitis C virus in liver cells constantly makes copies of itself, and the virus ends up not just in liver cells but also in the bloodstream. Treatment is intended to completely stop reproduction of the virus so that it doesn’t continue to enter the bloodstream or cause any more injury to liver cells.

Successful treatment results in a “sustained virological response.” This means the virus becomes completely undetectable before the treatment is finished, and it remains undetectable for 6 months after treatment is stopped.

A “relapse” means the viral load drops to an undetectable level before treatment is completed, but becomes detectable again within 6 months after treatment is stopped. Even if the virus returns at a level that is lower than it was before treatment, a relapse is still considered to have occurred. A relapse can be determined if the viral load starts to rise during treatment, or at any time after the virus becomes undetectable.

A “nonresponse” means the viral load never drops significantly and the virus remains detectable throughout the course of treatment.

Meaning Of Hcv Viral Load

The number of HCV RNA international units per milliliter of blood must be measured before treatment and during the course of treatment, to assess response. Before treatment, however, the HCV viral load is not related to the patient’s liver disease severity or HCV prognosis. This is important for patients and providers to understand.

Note: In hepatitis B, unlike hepatitis C, a higher HBV DNA viral load does correlate with increased disease severity and increased likelihood of outcomes such as hepatocellular carcinoma.

Interpreting Hcv Rna Test Results

It is essential that the provider understands how to interpret HCV RNA test results, especially during the course of HCV treatment.

Result of HCV RNA Test Interpretation
A quantified viral load — any exact number Ongoing HCV infection
“Detected” The HCV RNA is detectable but the number of international units is so low that it cannot be quantified accurately. This indicates extremely low level of virus is present.
“< 12 IU/mL” or “< 15 IU/mL” or “< 25 IU/mL” All of these are “less than the LLOQ” HCV RNA is undetectable. No virus is detected at all in the patient’s serum specimen.

Reactive Or Positive Hepatitis C Antibody Test

  • A reactive or positive antibody test means that Hepatitis C antibodies were found in the blood and a person has 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 even if they have cleared the Hepatitis C virus.
  • A reactive antibody test does not necessarily mean that you have Hepatitis C. A person will need an additional, follow-up test.

Persons for Whom HCV Testing Is Recommended

  • Adults born from 1945 through 1965 should be tested once
  • Those who:
  • Ever injected drugs, including those who injected once or a few times many years ago
  • Have certain medical conditions, including persons:
  • who received clotting factor concentrates produced before 1987
  • who were ever on long-term hemodialysis
  • with persistently abnormal alanine aminotransferase levels
  • who have HIV infection
  • Were prior recipients of transfusions or organ transplants, including persons who:
  • were notified that they received blood from a donor who later tested positive for HCV infection
  • received a transfusion of blood, blood components, or an organ transplant before July 1992
  • HCV- testing based on a recognized exposure is recommended for:
  • Healthcare, emergency medical, and public safety workers after needle sticks, sharps, or mucosal exposures to HCV-positive blood
  • Children born to HCV-positive women
