Typhi Dot, IgG
Understanding Typhi Dot, IgG
What is Typhi Dot, IgG?
The Typhi Dot, IgG test is a blood test used to detect the presence of Immunoglobulin G (IgG) antibodies against Salmonella typhi, the bacteria that causes typhoid fever. This is a rapid test that helps detect past typhoid infections, monitor immunity, and aid in managing typhoid fever.
Typhoid fever, or enteric fever, is a bacterial infection that manifests as fever, loss of appetite, stomach pain, diarrhea, and skin rash. You can get tested with the Typhi Dot, IgG test if you experience any symptoms suggestive of typhoid, have been in contact with a typhoid patient, or have traveled to an area where typhoid is prevalent. Typhoid fever is a potentially serious and life-threatening infection if left untreated.
The Typhi Dot, IgG test helps confirm whether an individual has been exposed to Salmonella typhi bacteria in the past. This is particularly important in regions where typhoid fever is endemic or for individuals who have traveled to areas where typhoid fever is prevalent. It also helps determine an individual’s immune status regarding typhoid, offering insights into whether they have acquired immunity through prior infection or vaccination.
Lab test results may vary across different laboratories. Abnormal test results require an expert interpretation; therefore, never try to self-medicate at home based solely on these results, and always consult a doctor for a proper understanding of the test results. The insights from this test help the doctor tailor an appropriate treatment plan. However, practicing good hygiene, being cautious with food and water handling, and getting vaccinated can reduce your risk of contracting typhoid fever.
What is Typhi Dot, IgG used for?
The Typhi Dot, IgG test is done:
- As part of the fever panel to determine the cause of the fever.
- In case of signs or symptoms of typhoid (enteric) fever, such as headache, high fever, abdominal pain, diarrhea, weight loss, or skin rashes.
- To check for a previous typhoid infection
- To screen people who are at a high risk of contracting typhoid fever, such as those who have just returned from a trip to a region where the illness is widespread or who have recently come in contact with infected people.
- To evaluate a patient’s response to typhoid fever treatment and to determine treatment effectiveness.
What does Typhi Dot, IgG measure?
The Typhi Dot, IgG test is performed to detect the presence or absence of IgG antibodies against Salmonella typhi, the bacteria that causes typhoid fever. IgG antibodies are the most frequent type of antibody, which are developed at a later stage, usually 2-3 weeks after the virus invades the body and causes the infection, and it remains in the body for life. Thus, IgG antibodies indicate if an individual has been infected with typhoid.
