What is the Widal Test - Tube Method?
The Widal test is a serological test used to diagnose enteric fever (typhoid and paratyphoid fever), caused by the bacteria Salmonella typhi and Salmonella paratyphi. The tube method is a more traditional and quantitative approach, measuring the levels of specific antibodies (O and H antigens) against these bacteria in the patient’s blood. This test helps determine the presence and extent of infection by detecting agglutination (clumping) of the bacteria when exposed to specific antibodies in the serum.

Purpose of the Widal Test - Tube Method:

1. Diagnose Typhoid and Paratyphoid Fever:

   • Identifies the presence of antibodies against Salmonella typhi and Salmonella paratyphi, indicating active or recent infection.

2. Monitor Disease Progression:

   • Helps assess the severity and stage of the disease by measuring antibody titers, which may rise as the infection progresses.

3. Evaluate Response to Treatment:

   • Monitors changes in antibody levels to evaluate the effectiveness of antibiotic therapy.

Sample Type:
Blood sample (serum).

Preparation for the Test:

• Fasting: Fasting is not required for the Widal test. You can eat and drink normally unless otherwise instructed by your healthcare provider.
• Medications: Inform your healthcare provider about any medications or antibiotics you are taking, as these may affect the test results.

Collection Method:

• A blood sample is drawn from a vein in your arm using a sterile needle. The serum is then mixed with antigen suspensions of Salmonella O and H antigens in test tubes. The degree of agglutination (clumping) observed determines the antibody titers, indicating the presence and extent of infection.
