Typhidot, IgM
Typhoid, commonly known as enteric fever, is caused by the bacterium Salmonella typhi. It spreads through the consumption of contaminated foods, beverages, and drinking water. When bacteria infect the body, the immune system produces various antibodies to fight the illness. IgM antibody is one of these antibodies that are produced during an early infection.
These IgM antibodies can be detected using typhidot IgM test, produced in response to Salmonella typhi infection in the body. This test is performed to determine the cause of any persistent fever or the presence of signs and symptoms of typhoid fever

Stomach pain
Headache
Diarrhoea
Cough
Loss of appetite
Spots all over the body (rose-shaped)

What is the turnaround time (TAT) for Typhidot IgM test?
The typhidot IgM test results are usually available within 1 – 2 working days after the sample collection. However, it can also take a little longer at times
What is the procedure involved in sample collection during typhidot IgM test?
A healthcare professional inserts a small needle into a vein in the arm to collect a few mL of blood sample in a sterile test tube. For easy collection of the blood sample, he may tie an elastic band to your upper arm or may ask you to make a fist

No, there are no potential risks associated with typhidot IgM test. It is a simple blood test and may involve negligible risks such as feeling a slight sting or a bruise at the site of needle insertion. It usually resolves within a few minutes to a couple of hours. Rarely, the site can also become infected
Can the test results be false-negative?
Yes, when the test is performed before the antibodies are generated, false-negative results may occur. After initial infection with Salmonella typhi bacteria, it normally takes about 1 to 2 weeks for antibodies to be developed. Any test performed prior to this time period may yield false-negative test results
What are the preventive measures that can be taken to avoid getting typhoid fever?
