INTRODUCTION

Typhoid fever is caused by S. typhi, a Gram-negative bacterium. World-wide an estimated 17 million cases and 600,000 associated deaths occur annually1. Patients who are infected with HIV are at significantly increased risk of clinical infection with S. typhi2. Evidence of h. pylori infection also presents an increase risk of acquiring typhoid fever. 1-5% of patients become chronic carrier harboring S. typhi in the gallbladder.

INTENDED USE

ACCU-TELL® Typhoid Rapid Test Cassette (Whole Blood/Serum/Plasma) is a rapid chromatographic immunoassay for the simultaneous detection and differentiation of IgG and IgM types of antibodies against Salmonella typhi (S. typhi) in human whole blood, serum or plasma. It is intended to be used as a screening test as an aid in the diagnosis of infection with S. typhi. Any reactive specimen with ACCU-TELL® Typhoid Rapid Test Cassette (Whole Blood/Serum/Plasma) needs to be confirmed with alternative testing method.

1. Bring the pouch to room temperature before opening it. Remove the test cassette from the sealed pouch and use it within one hour. Best results will be obtained if the assay is performed within one hour.

2. Place the test cassette on a clean and level surface.

For Serum or Plasma specimen:

3. Hold the dropper vertically and transfer 1 drop of serum or plasma (approximately 40μL) to the specimen well of test Cassette， then add 1 drop of buffer (approximately 40μL) and start the timer. Avoid trapping air bubbles in the specimen well. See the illustration above.

For Venipuncture Whole Blood specimen:

3. Hold the dropper vertically and transfer 1 drop of whole blood (approximately 40 μL)to the specimen well, then add 2 drops of buffer (approximately 80μL), and start the timer. See illustration above.

For Finger stick Whole Blood specimen:

3. To use a capillary tube: Fill the capillary tube and transfer approximately 40μL of finger stick whole blood specimen to the specimen area of test cassette, then add 2 drops of buffer (approximately 80μL) and start the timer. See illustration above.

4. Wait for the colored line(s) to appear. The result should be read at 15 minutes. Do not interpret results after 15minutes.
