Hepatitis C Virus (HCV) Test - Qualitative

The hepatitis C virus (HCV) qualitative test, also known as the HCV qualitative test, helps doctors check whether the hepatitis C virus is currently present in your blood. Hepatitis C is a virus that spreads through infected blood and causes liver inflammation, which can lead to serious long-term conditions such as cancer or liver cirrhosis (a disease that causes permanent damage to the liver).

The HCV qualitative test looks for the virus’s genetic material in the blood to see whether it is active. This is different from the hepatitis C antibody test, which only shows whether your body has been exposed to the virus. The qualitative test tells you whether the virus is currently active.

Laboratory reports also describe it as a qualitative nucleic acid test for HCV RNA. Doctors often recommend this test after they find HCV antibodies (proteins your body makes to help fight germs) in the blood. If you were exposed to the virus within the last 6 months, the doctor will order an HCV qualitative test. Early diagnosis enables doctors to initiate treatment promptly and prevent complications.

A doctor might advise a hepatitis C virus qualitative test in individuals with the following symptoms of HCV infection, to assess the presence of the disease:

• Fever
• Fatigue
• Abdominal pain
• Nausea
• Vomiting
• Decreased appetite
• Jaundice (causes yellowing of the skin and eyes)
• Pruritus (itchy skin)
• Lethargy (tiredness)
• Anxiety
• Depression

Categories of people who should take this test:

• People with symptoms of hepatitis: This includes individuals with relevant symptoms, such as jaundice, fever, nausea, abdominal discomfort, and tiredness.
• People who have been exposed to the hepatitis C virus: This includes individuals exposed to blood from a person with hepatitis C or who have been in sexual relationships with them.
• People at higher risk of hepatitis C infection: This includes individuals who are blood donors, share needles or syringes while injecting drugs, have liver disease involving the virus, have had a needlestick injury, have tattoos or body piercings done with unsterile tools, and babies born to hepatitis C-infected mothers.
• People with a positive hepatitis C antibody test: Repeat testing is usually done in individuals who test positive for hepatitis C antibodies.

The test is performed based on your health, your risk of exposure to the virus, and when recommended by your doctor, as shown in the table below.

A hepatitis C virus qualitative test can help detect an active HCV infection and evaluate the need for treatment.

What to Expect Before the Hepatitis C Virus (HCV) Test

No fasting is required for a standalone Hepatitis C Virus (HCV) test. You can eat and drink normally. However, if it is part of a broader package that includes fasting tests, your doctor may advise fasting for 8-12 hours. Avoid strenuous exercise for 24 hours before the test, as intense physical activity can temporarily raise Hepatitis C Virus (HCV) levels and affect interpretation. Always inform your doctor about any ongoing medications.

What to Expect During the Blood Collection

A phlebotomist cleans the skin with an antiseptic, then places an elastic band around your upper arm to make the veins easier to access. A small needle is inserted into the vein; you may feel a brief pinch. Blood is collected into a labelled tube in under a minute.

What to Expect After the Hepatitis C Virus (HCV) Test

A small cotton swab and bandage are placed over the site to stop any minor bleeding. You can return to normal activities immediately. Minor bruising is normal and disappears quickly. If dizzy, sit and rest for a few minutes.

The key parameter in the hepatitis C virus qualitative test is:

• Presence of (HCV) RNA

The following table shows the HCV qualitative test result:

Note:

• Test results should always be evaluated by a qualified doctor along with symptoms and medical history.

The table below provides a general interpretation of HCV qualitative test results based on whether the test detects the virus.

The hepatitis C virus qualitative test is generally safe and involves minimal risk.

• Slight bleeding, bruising, or soreness may be seen at the injection site. This usually goes away on its own.

Limitations:

• It cannot be used alone to diagnose an HCV infectious disease.
• Other follow-up tests must be done to confirm the diagnosis, in addition to this test.
• A ‘not detected’ result does not completely rule out HCV active infection.
• Results showing ‘detected’ should be considered together with other tests and clinical findings.

Depending on your HCV qualitative test results, and symptoms, your doctor may recommend additional tests to confirm a diagnosis or identify the underlying cause:

• Gamma-Glutamyl transferase test (GGT)
• Complete blood count (CBC)
• Bilirubin test
• Liver function tests
• Liver ultrasound
• Liver biopsy
