To test whether you have been infected with HCV, your blood sample is tested for the presence of antibodies against HCV. These antibodies generally take 8 to 11 weeks to be detectable after exposure to HCV.
HCV positive (reactive) is an interpretation of the results of the HCV antibody test that may mean the following:
- The person is infected with HCV at some point in time.
- It does not necessarily mean hepatitis C is current. Hence, a follow-up screening test is required.
- Once a person is infected, they will carry the antibodies for the rest of their life although they have been cured or recovered or maybe the virus is still present in the blood.
If the antibody test is reactive or positive, the doctor may recommend an additional test to see if the person currently has hepatitis C. The test is called nucleic acid test or polymerase chain reaction test that detects HCV RNA, which can be interpreted as follows:
- Negative: This shows a past infection with HCV, and the virus is no longer present in the body because the person is cured of the infection naturally.
- Positive: This shows the infection is current, and the virus is present in the body that can be spread to others.
What is hepatitis C?
Although hepatitis can be caused by heavy alcohol consumption, toxins, certain medical conditions, and some medications, the most common cause of hepatitis is a viral infection due to hepatitis A, B, and C virus.
Two types of hepatitis C include:
- Acute: It is a new or recent infection within six months of initial exposure to the virus. For some people, acute may turn into a chronic infection.
- Chronic: If left untreated, hepatitis can turn into a lifelong infection, leading to serious health issues including cirrhosis (scarring and hardening of the liver), liver damage, liver cancer, liver failure, and even death.
2 symptoms of hepatitis C
Two symptoms of hepatitis C include:
- Acute hepatitis C:
- Most people infected recently with hepatitis C virus (HCV) do not show any symptoms and thus are unaware of their infection, whereas some may develop symptoms usually 2 to 12 weeks after exposure to HCV and may include:
- Chronic hepatitis C:
What causes hepatitis C?
A person may get infected with the hepatitis C virus (HCV) through exposure to contaminated body fluids such as blood and semen of an infected person.
Modes of transmission may include:
- Sharing or using infected needles for medications, drugs, piercings, and tattoos
- Unprotected sex with the infected person
- Getting treated with unsterile or infected surgical instruments
- Sharing daily routine items (containing body fluids) such as toothbrushes, nail cutters, razors, or piercing jewelry
- Blood transfusions and organ transplants
- Being born to an infected pregnant female
HCV does not spread by:
- Hugging, shaking hands, or touching
- Cheek or lip kissing
- Sneezing or coughing
- Consuming food prepared or touched by an infected person
- Breastfeeding (women with bleeding or cracked nipples, however, should temporarily stop breastfeeding till their nipples completely heal)
- Sharing utensils such as spoons or forks
- Mosquito bites
Who are at a risk of hepatitis C infection?
People who are at risk of hepatitis C include:
- People who have unprotected sex
- People who are diagnosed with other sexually transmitted diseases
- Children born to infected women
- Health-care providers
- People who tend to share needles and syringes
- People who live in high-risk countries
- Vulnerable people who live in prisons and old age homes
- People on dialysis and those with persistently abnormal alanine aminotransferase levels (an enzyme found within the liver cells)
- Men who have sex with men
- People who are tested positive for the human immunodeficiency virus
- People who have multiple sex partners
A person can get reinfected with HCV even if they have been successfully treated and cured. Thus, it is recommended that people who inject and share needles, syringes, or other types of equipment, along with those who receive maintenance hemodialysis, should be screened for hepatitis C regularly.
4 ways to diagnose hepatitis C
Four ways to diagnose hepatitis C virus (HCV) include:
- Blood examination: Blood tests may include
- HCV antibody test: This test screens antibodies (proteins released into the bloodstream by the immune system of someone infected with hepatitis C virus [HCV]) against HCV.
- Liver function test: It is the measurement of proteins and enzymes that usually rise seven to eight weeks after the infection.
- HCV RNA: This test detects the genetic material of the virus and helps diagnose the presence of active infection.
- Abdominal ultrasonography: An ultrasound shows the size, shape, and blood flow to the liver.
- Liver biopsy: Liver tissue sample is removed through a small incision and analyzed under the microscope.
Is hepatitis C serious?
Hepatitis C can begin as a short-term infection, but in some people, the virus may remain in the body and cause chronic (long-term) infection.
Almost half of the people infected with the hepatitis C virus may develop a chronic infection that can turn into a serious and long-term health problem, leading to cirrhosis, permanent liver damage, liver cancer, and death.
How is hepatitis C treated?
Many people infected with hepatitis C virus clear it from their bodies without any treatment, whereas some may require treatment and lifestyle modifications including:
Can hepatitis C be prevented?
Currently, there is no vaccine for hepatitis C, but it is recommended to be vaccinated against hepatitis A and B.
Other precautionary measures recommended by the World Health Organization include:

Hepatitis C (HCV, Hep C)Hepatitis C is an inflammation of the liver due to the hepatitis C virus (HCV), which is usually spread by blood transfusion, hemodialysis, and needle sticks, especially with intravenous drug abuse. Symptoms of chronic hepatitis include fatigue, fever, muscle aches, loss of appetite, and fever. Chronic hepatitis C may be cured in most individuals with drugs that target specific genomes of hepatitis C.
Hepatitis C Cure (Symptoms, Transmission, Treatments, and Cost)
Hepatitis is inflammation of the liver. There are a variety of toxins, diseases, illicit drugs, medications, bacterial and viral infections, and heavy alcohol use can case inflammation of the liver. Hepatitis C viral infection (HCV) is one type of hepatitis. According to the CDC, in 2014 there were an estimated 30,500 cases of acute hepatitis C infections in the US. An estimated 2.7-3.9 million people in the US have chronic hepatitis C. The virus is spread from person-to-person via blood-to-blood contact.
Symptoms of HCV infection include joint pain, jaundice, dark urine, nausea, fatigue, fever, loss of appetites, clay colored stool. Hepatitis C can be cured with medications in most people. There is no vaccine against the hepatitis C virus.

How Long Can a Person Live After Being Diagnosed With Hepatitis C (Hep C)?Hepatitis C is a virus that causes inflammation of the liver. The impact of hepatitis C on lifespan is dependent on how the disease progresses and the effectiveness of timely treatment.
Is Hepatitis C Contagious?Hepatitis C or hep C causes acute and chronic liver disease. Hep C is a form of liver disease with symptoms like fatigue, jaundice, nausea and vomiting, anorexia, and abdominal discomfort. Hepatitis C is a contagious viral infection caused by people sharing drug needles, surgical instruments that have not been properly sanitized, and organ transplantation.
Is Hepatitis Contagious?Hepatitis means "inflammation of the liver," and there are several different types of such as A, B, C, D, and E. Some types of hepatitis are contagious and some types are not. Hepatitis symptoms vary upon the type of disease; however, the following symptoms may develop in someone with hepatitis: fatigue, nausea and vomiting, abdominal pain and discomfort, jaundice (yellowing of the skin and whites of the eyes), and loss of appetite. Treatment for hepatitis depends upon the cause. Some types of hepatitis have a vaccine to prevent spread of disease such as hepatitis A and B.

Hepatitis (Viral Hepatitis A, B, C, D, E, G)
Hepatitis is most often viral, due to infection with one of the hepatitis viruses (A, B, C, D, E, F (not confirmed), and G) or another virus (such as those that cause infectious mononucleosis, cytomegalovirus disease). The main nonviral causes of hepatitis are alcohol and drugs. Many patients infected with hepatitis A, B, and C have few or no symptoms of illness. For those who do develop symptoms of viral hepatitis, the most common are flu-like symptoms including: loss of appetite, nausea, vomiting, fever, weakness, tiredness, and aching in the abdomen. Treatment of viral hepatitis is dependent on the type of hepatitis.
What Does it Mean If You Have Urobilinogen in Your Urine?Urobilinogen is a substance that is produced when bilirubin, a waste product produced by the breakdown of red blood cells, is processed in the liver and released into the intestine. Excess urobilinogen in urine may indicate liver diseases, such as viral hepatitis, cirrhosis, or liver damage. It is caused by drugs, toxic substances, or conditions associated with increased red blood cell destruction (hemolytic anemia). In a person with low urine urobilinogen and/or signs of liver dysfunction, it can be indicative of hepatic or biliary obstruction.
What’s Worse, Hepatitis A, B, or C?Because there is no vaccination available against hepatitis C, hepatitis C is often considered worse than hepatitis A or B.
