2. Understanding Hepatitis C: Why Testing Matters

What is Hepatitis C Virus (HCV)?

Hepatitis C is a blood-borne viral infection that primarily affects the liver. Once inside the body, the virus can persist for decades, gradually damaging hepatic tissue.

Modes of Transmission and High-Risk Populations

HCV spreads through exposure to infected blood. Common transmission routes include:

• Injection drug use and needle sharing
• Transfusion of unscreened blood products (historically)
• Occupational exposure among healthcare workers
• Non-sterile medical or cosmetic procedures
• Vertical transmission from mother to child (less common)

High-risk groups include individuals with a history of intravenous drug use, recipients of blood transfusions before routine screening, dialysis patients, and individuals with multiple medical exposures.

Symptoms of Acute and Chronic Infection

Most acute infections are asymptomatic. When present, symptoms may include fatigue, jaundice, nausea, or abdominal discomfort. Chronic infection often progresses silently.

Risks of Untreated Infection

• Chronic hepatitis
• Liver fibrosis and cirrhosis
• Liver failure
• Hepatocellular carcinoma

Screening plays a pivotal role in disease control, enabling early treatment and reducing long-term complications.

4. How the iCare Hepatitis C Test Kit Works (Mechanism of Action)

The device utilizes an immunochromatographic lateral flow assay. This technology allows rapid detection of antibodies produced in response to HCV infection.

How to test for Hepatitis C

A small blood sample is applied to the sample well. The buffer facilitates capillary migration across the membrane. If anti-HCV antibodies are present, they bind to specific antigens and form a visible test line.

Reaction Process

• Sample application
• Migration through reagent zone
• Antigen-antibody binding
• Appearance of control and test lines

Results are typically available within 10–20 minutes. Reading outside the recommended time window may compromise accuracy.

The test is designed with high sensitivity and specificity, although confirmatory laboratory testing remains essential for diagnosis.
