Hepatitis C Antibody Blood Test
Test Code: 140659
Specimen Type: Blood
Hepatitis C Antibody Blood Test (Labcorp)
The Hepatitis C Abs test is the most commonly ordered screening for Hepatitis C (HCV) 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 qualitative and will indicate a reactive (positive), nonreactive (negative), 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:
• Loss of appetite
• Abdominal pain
• Dark-colored urine
• Grey feces
• Jaundice (yellowing of the skin or eyes)
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 (prior to the early 1990s when stricter screening techniques were implemented for donated blood), 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. A positive Hep C antibody result cannot differentiate between an active infection and a previously resolved infection. It is usually recommended to follow up a positive antibody test with a Hepatitis C RNA PCR Quantitative test.
The Hepatitis C RNA PCR Quantitative test can also be used to screen for a recent exposure when it is too early for the Hep C Ab test to be accurate.
Turnaround time for the Hepatitis C Abs test is typically 1-3 business days.

For the majority of people, this test will have the highest accuracy at 12 weeks from an exposure or anytime after. Some people may be detectable as early as 4 weeks from exposure. In rare circumstances, it could take past 6 months to be detectible.
It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample.STD Overview
