Description
Key Features:
- Rapid Results: Provides results within 15–20 minutes.
- Sample Types: Suitable for use with serum or plasma.
- Ease of Use: Simple, one-step procedure requiring minimal training.
- No Equipment Required: Ideal for use in field settings or resource-limited areas.
- High Sensitivity and Specificity: Accurately detects anti-HBs antibodies.
Test Procedure:
- Sample Collection: Collect a serum or plasma sample from the patient.
- Test Setup: Place the test device on a flat surface and add the sample to the designated sample well.
- Buffer Addition: Add the provided buffer to the sample well.
- Incubation: Allow the test to develop for 15–20 minutes.
- Result Interpretation:
- Positive: Both the control line (C) and the test line (T) appear, indicating the presence of anti-HBs antibodies.
- Negative: Only the control line (C) appears, indicating no detectable anti-HBs antibodies.
- Invalid: No control line appears, indicating the test is invalid and should be repeated.
Result Interpretation:
- Positive Result: Indicates the presence of protective antibodies, suggesting immunity to hepatitis B from vaccination or previous infection.
- Negative Result: Indicates no detectable anti-HBs antibodies, suggesting no immunity.
- Invalid Result: The test must be repeated using a new device.
Applications:
- Immunity Assessment: Used to check immune status after hepatitis B vaccination or past infection.
- Pre-Vaccination Screening: Determines the need for hepatitis B vaccination.
- Post-Vaccination Follow-Up: Monitors the effectiveness of the hepatitis B vaccine.
Storage and Stability:
- Store at 2–30°C (35.6–86°F).
- Keep the test away from direct sunlight and moisture.
- The test should remain sealed until use to ensure accuracy.
Limitations:
- A negative result does not rule out the need for vaccination, especially in high-risk individuals.
- Positive results should be interpreted in the context of clinical and vaccination history.
- For professional use only.
