How to Book A Typhidot Test in Chennai?
What is included in the Typhidot test?
This test measures the level of specific antibodies formed in the body against Salmonella Typhi bacteria. This bacteria causes typhoid fever. This test mainly includes a ready-to-use test kit on which the blood sample is placed, and then it is combined with certain chemicals which are already provided within the test kit. It takes at least 1 to 3 hours to show the results of the test. The test results are then compared to the kit’s readings or range already provided.
Procedure for Typhidot test
A tourniquet (elastic) band is placed tightly on the upper arm to take the blood sample. The patient is asked to make a fist. This helps in the buildup of blood filling the veins, and it becomes easy to collect the blood. The skin is cleaned before inserting the needle in the vein to prevent bacteria from entering. The needle is then inserted into the vein in the arm, and the blood sample is collected in the vacutainer.
This blood sample is then placed on the Typhidot test kit, which is combined with some special chemicals. It takes at least one to three hours for the results to show. You will find the readings already provided in the test kit so that you can compare the outcome to know if you have typhoid fever or not.
How to prepare for the Typhidot test?
You have to take no special precaution prior to this test. But make sure to inform the doctor about any underlying condition or medications that you might be taking.
Things to consider after the Typhidot test is complete
The Typhidot test is easy to perform and does not require you to take any special precautions before or after the test. But it is recommended that you inform the doctor about any past medication or any underlying disease that you may be having. After the blood sample is drawn, the area may bruise, but even that is rare, and there is no risk involved in it.
*What types of infection can the Typhidot test detect?
The Typhidot test mainly helps to detect the level of certain antibodies that are produced in response to the presence of the Salmonella Typhi bacteria in the body.
How much does the Typhidot test cost?*
The cost of a Typhidot test varies from one pathology lab to the next. The Typhidot test, on the other hand, is typically not too expensive and is easily accessible. The pricing of the Typhidot test at home is also different from that of typical pathological labs. The majority of test lab centres charge in the range of Rs.300 to Rs. 500 for this test.
*Disclaimer: The value varies based on location, time, and your preferred lab partner.
How long does it take to get the results for the Typhidot test?
You can expect to get the results for the Typhidot test within 24 to 48 hours after the sample is collected. However, in some instances, depending on the location, medical advice, and preferred lab partner, it may take longer.
What do abnormal Typhidot test results indicate?
The Typhidot test mainly helps to detect the IgM and IgG antibodies produced in the presence of the Salmonella Typhi bacteria, and hence, are needed to detect acute typhoid fever. A negative result for the anti-salmonella IgG and IgM antibodies mainly indicates that there is no infection.
But if the test shows a positive result for the IgG antibodies, it indicates that there is an acute infection. But a positive result for the IgM antibodies will indicate any past or chronic infection. Make sure to consult the doctor for proper interpretation of the test results.
Disclaimer: Please consult with your doctor for interpreting the test reports.
Is the Typhidot test a definitive test?
Most general practitioners or consultants mostly use the Typhidot test for the diagnosis of typhoid fever. This test is still considered to be definitive regardless of its low sensitivity and specificity, which may further result in the misdiagnosis of the infection. Hence, it could hamper the treatment of the patient. But as a matter of fact, this test is still preferred by many as it gives quick results and is easy to use and affordable.
How to read the Typhidot test report?
The Typhidot (or Widal Test) is a fast serological test for typhoid illness diagnosis. The Typhidot test is a dot ELISA kit that detects IgM and IgG antibodies against the Salmonella Typhi outer membrane protein (OMP). Hence, if someone is diagnosed with typhoid fever, they must do the Typhidot test to know the results.
A negative result for the anti-salmonella IgG and IgM antibodies mainly indicates that there is no infection. But if the test shows a positive result for the IgG antibodies, it indicates an acute infection. But a positive result for the IgM antibodies will indicate any past or chronic infection. Make sure to consult the doctor for proper interpretation of the test results.
Typhidot test at home – how does it work?
The Typhidot test is just like any other blood test. A lab technician visits your home when you book your tests through the MFine app. The lab technician first cleans the arm and then inserts a syringe into a vein. The required amount of blood is then taken into a vial. The lab technician then removes the needle and places cotton wool or a bandage over the prick.
Are there any risks involved with the Typhidot test?
There are no such risks involved with the Typhidot test. However, it is better to take the doctor’s suggestion if you want a proper test diagnosis. The Typhidot distinguishes between IgM and IgG antibodies to the bacterium. IgM indicates a recent infection, whereas IgG indicates a distant infection. But this test may not give a definitive result because a positive IgG value may also suggest that you may have had a previous infection or a chronic infection. For quick diagnosis of enteric fever, Typhidot fever may be beneficial.
What can affect the results of the Typhidot test?
If the results show a positive IgG value, it may be because of the presence of any past infection or chronic infection. On the contrary, a positive IgM value shows the presence of any recent infection. Hence, the end results may be better interpreted by a doctor.
Why Book the Typhidot Test?
- Typhidot test is defined as a rapid serological test that is used for the diagnosis of Typhidot. It is typically characterized by diarrhoea, progressive fever, and other infections related to salmonella infections.
- The test is regarded as a screening test that identifies IgM and IgG antibodies against membrane protein related to Salmonella typhi. It is, therefore, capable of identifying, diagnosing and monitoring fever related to Salmonella Typhi infections.

What does the Typhidot Test measure?
- The test is used to measure the levels of specific antibodies formed in the body against salmonella typhi bacteria. These particular bacteria are responsible for causing Typhoid.
- Hence, the test is indicated as a screening test that helps in the identification, monitoring, and diagnosis of salmonella-related infections.
What Preparation is Needed for the Typhidot Test?
- There is no need for any significant preparation or fasting for the test. It is an invasive test procedure where the respective personnel will collect either serum (blood) samples or any particular specimen (sputum, stool, or urine) from the patients. The sample is sent to specific laboratories for further testing and analysis.
- However, it is crucial to inform the doctor about your medical history, if any.
What Happens to Your Test Sample?
What do Abnormal Results Indicate?
- Typhidot test result is interpreted by the emergence of Agglutination.
- Agglutination indicates a positive test result in case a positive reaction is determined in 20 µl of a test sample. This is indicative of the presence of clinically significant levels of the corresponding antibody in the patient serum sample.
- The absence of agglutination indicates negative test results, thereby specifying the absence of specific antibodies in patient serum levels.
- Samples demonstrating a titer of 1:100 or more O agglutinations and 1:200 or more for H agglutination may be regarded as clinically significant samples.
- A four-fold rise between the two is deemed to be diagnostic.
- Disclaimer: It has been advised to always consult with your doctor for interpreting the test reports.
