It is a simple and rapid serological diagnostic test to identify IgM antibodies against Salmonella typhi, in typhoid fevers.
Typhoid fever has been endemic in India and other developing countries. After one gets infected with the organism, it takes about 7 to 10 days before a Widal test can diagnose it. There is therefore a continuous need for a simple test which can be carried out in small laboratories for rapid diagnosis of typhoid in these countries. Typhi dot IgM test has been introduced to detect IgM antibodies against Salmonella typhi.
The test should be performed if the patient shows following signs and symptoms:
A blood sample will be collected from a vein in your arm. The patient does not have to be fasting for doing the test.
The spot test just diagnosis the presence and absence of antibodies for Salmonella typhi. A detailed report can be obtained by doing a Widal test at appropriate time.
