DIAGNOSTIC TESTS FOR HEPATITIS C AND WHO SHOULD GET TESTED?

Testing for hepatitis C is most essential for individuals at high risk because this is a disease with potentially severe complications.

Eligible candidates for hepatitis C diagnostic testing include:

  • All adults aged 18 to 79 are recommended to undergo hepatitis C testing, even if they do not exhibit any symptoms of liver disease. Hepatitis C screening is especially crucial for those at high-risk exposure:
  • Individuals with a history of intravenous drug use.
  • People with abnormal liver function test results that cannot be attributed to a known cause.
  • Babies born to mothers with hepatitis C.
  • Healthcare workers who may have had accidental blood exposure or needlestick injuries.
  • Individuals with bleeding disorders.
  • Patients who have undergone long-term hemodialysis treatment.
  • Those who have received blood transfusions or organ transplants before 1992, when more rigorous screening measures were implemented.
  • People with multiple sexual partners or who have sexual partners at risk of hepatitis C infection.
  • Those co-infected with HIV.
  • Individuals aged 55 and above.
  • Anyone with concerns about their potential risk.

Diagnostic Tests for Hepatitis C

Blood tests are conducted to examine the following factors:

  1. HCV Antibodies (Anti-HCV): These are proteins that the body produces when the hepatitis C virus is present in the blood. They usually appear about 12 weeks after infection. Results typically take a few days to a week.
    • A negative result means no hepatitis C virus is detected. In such cases, retesting is recommended if there are suspicious factors within 6 months.
    • A positive result indicates the presence of hepatitis C virus antibodies in the blood, meaning the person has been infected.

If the antibody test is positive, the following additional tests are typically conducted:

  1. RNA Testing: Measures the amount of hepatitis C virus RNA (genetic material from the virus) in the blood, often detectable 1-2 weeks after infection. The results can help diagnose the patient’s infection status and its level.
  2. Liver Function Tests (LFT) or Hepatic Enzyme Tests: These tests help doctors understand the liver’s activity. Elevations in liver enzymes can occur 7-8 weeks after infection, though it is not the sole indicator of hepatitis C infection as elevated liver enzymes can also be due to other liver conditions.

Additional Diagnostic Tests After Diagnosis:

Once a patient is diagnosed with hepatitis C, further diagnostic tests may be conducted to understand the patient’s condition better, such as:

  • Genotype Testing: Identifies which of the six genotypes of hepatitis C the patient has.
  • Tests for Liver Damage Assessment:
    • Computed Tomography (CT) Scans
    • Magnetic Resonance Imaging (MRI)
    • Magnetic Resonance Elastography (MRE)
    • Ultrasound
    • Liver Biopsy

These test results assist doctors in determining the appropriate treatment approach.

Preventive Measures to Reduce the Risk of Hepatitis C Transmission

Hepatitis C can be transmitted through blood contact, and even a small amount of blood exposure can lead to infection. To reduce the risk of transmission, consider the following preventive measures:

  1. Avoid Sharing Needles: Using shared needles or any injection equipment, including those for drug use, can transmit hepatitis C. Always use clean, sterile needles and never share them.
  2. Avoid Direct Contact with Blood or Blood Products: This is especially important for healthcare workers. All blood-contaminated products must be handled safely and sterilized to prevent infection.
  3. Do Not Share Personal Items: Personal items that may come into contact with blood, such as razors, toothbrushes, nail clippers, or scissors, can potentially transmit the hepatitis C virus. Keep these items separate, and keep them out of the reach of children.
  4. Safe Tattooing and Piercing: When getting tattoos or piercings, choose reputable, licensed establishments that follow proper hygiene and sterilization procedures. It’s essential to remain loyal to one establishment and avoid unlicensed, unsanitary locations.
  5. Practice Safe Sex: While hepatitis C is rarely transmitted sexually, it can be spread through sexual contact if there is blood exposure. Practice safe sex, especially with multiple partners or if your partner has hepatitis C or sexually transmitted infections like syphilis.
  6. Screen Blood Donations: For individuals donating blood, it’s crucial to undergo screening or testing before using the donated blood for transfusions or surgeries.
  7. Vaccinations: There is no vaccine available to prevent hepatitis C infection. However, there are vaccines for hepatitis A and hepatitis B, which can help protect the liver from damage.

Note: Hepatitis C is a medical condition, and it is essential to consult with healthcare professionals for accurate information, testing, and treatment options.

Lifestyle Changes

It’s advisable to make lifestyle changes to improve your overall health, such as:

  1. Quit Alcohol: Stopping alcohol consumption is essential to protect your liver.
  2. Healthy Eating: Consume a nutritious, fiber-rich diet to reduce the strain on your liver. Avoid processed foods and opt for fresh fruits and vegetables.
  3. Medication Management: Avoid medications that may harm your liver. Always consult with a healthcare professional about the potential risks to your liver when taking any medication.
  4. Regular Exercise: Engage in regular physical activity to maintain a healthy body and strengthen your immune system.
