The Typhifast IgG, IgM test is a serological test used to detect the presence of specific antibodies—Immunoglobulin G (IgG) and Immunoglobulin M (IgM)—against the Salmonella typhi bacteria.
IgM antibodies typically appear in the early stages of infection, indicating a recent or ongoing infection, while IgG antibodies indicate either a past infection or a long-term immune response. This test is highly valuable in diagnosing typhoid fever, particularly in regions where the disease is endemic and other diagnostic methods, such as blood cultures, may be less accessible or take longer to provide results.
1] IgM Antibodies: These are the first antibodies produced by the immune system in response to an infection. A positive IgM result generally indicates a recent or ongoing typhoid infection. IgM antibodies can be detected as early as 5 to 10 days after infection.
2] IgG Antibodies: IgG antibodies appear later in the course of infection, usually after IgM antibodies. Their presence suggests either a past infection or a continuing immune response. A positive IgG result may also indicate immunity due to previous exposure or vaccination.
The Typhifast IgG, IgM test is particularly useful in distinguishing between acute (current) and past infections, allowing healthcare providers to tailor treatment strategies more effectively.
The Typhifast IgG, IgM test is relatively simple and involves drawing a small sample of blood from the patient. Here’s an overview of the procedure:
1] Sample Collection: A healthcare provider will draw a blood sample from a vein in the arm using a syringe.
2] Laboratory Analysis: The blood sample is then processed in a laboratory, where it is tested for the presence of IgG and IgM antibodies against Salmonella typhi.
3] Results Interpretation: Results are typically available within a few hours to a day, depending on the laboratory’s processing speed. The results indicate whether the IgG, IgM, or both antibodies are present, helping diagnose the stage and type of infection.
1] Negative Result (IgG and IgM): If both IgG and IgM antibodies are absent, it usually indicates that the patient does not have a current or past typhoid infection. However, early-stage infections may not show detectable levels of antibodies, so repeat testing may be recommended if typhoid is still suspected.
2] Positive IgM and Negative IgG: A positive IgM result with a negative IgG result generally suggests a recent or acute typhoid infection. Immediate treatment is required to prevent complications.
3] Positive IgG and Negative IgM: A positive IgG result with a negative IgM result usually indicates a past infection or immunity from vaccination. This result suggests the patient has developed long-term immunity to Salmonella typhi.
4] Positive IgG and IgM: If both IgG and IgM antibodies are present, it suggests a current infection with a continuing immune response. This could also indicate reinfection in some cases.

No, the Typhifast IgG, IgM test is specific to Salmonella typhi, the bacteria responsible for typhoid fever. It cannot detect other bacterial or viral infections.
Yes, the Typhifast IgG, IgM test is safe for pregnant women. If you are pregnant and experiencing symptoms of typhoid fever, early diagnosis and treatment are crucial for both your health and the health of your baby.
No, fasting is not required for the Typhifast IgG, IgM test. You can eat and drink normally before the test.
The test is important because it can detect whether a person has an active or past infection of typhoid fever. It provides quick and valuable information about the body's immune response to the Salmonella typhi bacteria, allowing for timely treatment and management.
