Typhoid Test

What is the Typhoid Test?

The Typhoid Test is a rapid and easy-to-use at-home screening kit for typhoid and paratyphoid fever. It detects specific antigens from Salmonella Typhi and Salmonella Paratyphi A in stool samples. These bacteria are responsible for typhoid and paratyphoid infections, which are more common in regions with limited access to clean water and sanitation.

What Does the Test Detect?

This rapid test is a qualitative immunoassay that checks for the presence of S. Typhi and S. Paratyphi A antigens.

• Positive result: Antigens from Salmonella Typhi and/or Salmonella Paratyphi A are detected in the stool sample.
• Negative result: No antigens detected.

A positive result should always be confirmed with additional laboratory testing.

How Does the Test Work?

1. Collect a small stool sample using the provided collection tools.
2. Mix the sample with the included dilution solution as instructed.
3. Add the prepared mixture to the test cassette.
4. Read the result within 10–20 minutes.
   • A visible test line together with a control line indicates a positive result.
   • Only one control line indicates a negative result.
   • No control line means the test is invalid and should be repeated with a new device.

Symptoms of Typhoid and Paratyphoid Fever

Both typhoid fever and paratyphoid fever are bacterial infections that can cause similar symptoms, which may range from mild to severe. Common signs include:

• Persistent high fever
• Abdominal pain or stomach discomfort
• Headache and general fatigue
• Loss of appetite
• Diarrhea or constipation
• Sometimes skin rashes (known as “rose spots”)

Because these symptoms can also occur with other illnesses, testing provides a helpful first step in assessing possible typhoid or paratyphoid infection, especially after travel to areas where these diseases are more common.

When to Use This Test

The Typhoid Test may be useful if you:

• Experience symptoms such as fever, abdominal pain, or digestive issues after travel
• Want to check for possible typhoid or paratyphoid infection after visiting regions where these diseases are more common
• Need a quick and private screening option before consulting a healthcare professional

Why Choose This Test?

• Fast results: Clear answer in 10–20 minutes
• Easy to use: Includes all necessary materials for stool sample testing at home
• Detects specific antigens: Targets Salmonella Typhi and Salmonella Paratyphi A
• Discreet and private: Perform the test in the comfort of your home
• FDA listed & exempt: Registered and legally marketed for over-the-counter home use in the United States

Important to Know

• This test is a screening tool and detects only S. Typhi and S. Paratyphi A antigens. It does not detect other Salmonella strains that cause common foodborne illness.
• The test alone cannot confirm a diagnosis of typhoid or paratyphoid fever. Positive results should always be followed up with confirmatory laboratory testing and medical evaluation.
• A negative result does not completely rule out infection. If symptoms persist, especially after international travel, consult a healthcare professional.
• For best accuracy, use a fresh stool sample and carefully follow the included instructions.
