Typhidot Test – Salmonella IgG & IgM Antibodies Test
Typhidot Test – Salmonella IgG & IgM Antibodies Test
The Typhidot Test is a rapid serological test used to detect antibodies against Salmonella typhi, the bacteria responsible for typhoid fever. This test identifies both IgM and IgG antibodies, which indicate current or past infections.
Typhoid fever is a serious bacterial infection spread through contaminated food and water, leading to high fever, abdominal pain, diarrhea, weakness, and potential complications such as intestinal perforation. Early detection of Salmonella antibodies allows for timely treatment and prevention of complications.
What is the Typhidot Test Used For?
- Diagnosing acute typhoid fever by detecting IgM antibodies.
- Identifying past or chronic infections through the presence of IgG antibodies.
- Differentiating typhoid fever from other febrile illnesses, such as malaria and dengue.
- Providing a rapid alternative to traditional blood culture methods.
Symptoms of Typhoid
Fever
Fatigue
Stomach pain
Headache
Diarrhoea
Cough
Loss of appetite
Spots all over the body (rose-shaped)
Preparation for the Test
No fasting required. A blood sample is collected from a vein and analyzed for IgG and IgM antibodies. Inform your doctor about any recent antibiotic use, as it may affect results.
Interpretation of Test Results
A positive result should be confirmed with blood culture or Widal test for definitive diagnosis.
IgM Positive- Suggests an active or recent infection with Salmonella typhi.
IgG Positive- Indicates past exposure or a chronic carrier state.
IgM & IgG Negative- No detectable antibodies; typhoid infection unlikely.
FAQs
How is the Typhidot test different from the Widal test?
The Typhidot test detects specific antibodies rapidly, while the Widal test measures agglutination reactions and may take longer.
Can the Typhidot test confirm typhoid fever?
It helps in diagnosis, but blood culture remains the gold standard for confirmation.
How long does it take to receive results?
Results are typically available within 2 to 4 hours, making it a quick diagnostic tool.
Can antibiotics affect test results?
Yes, prior antibiotic use may reduce antibody levels, leading to false-negative results.
What should I do if my test is positive?
Consult a doctor for antibiotic treatment and follow hygiene precautions to prevent spread.
