The Widal Test is a diagnostic tool that requires a blood (serum) sample to detect and evaluate the presence of typhoid fever. During this test the lab technician will draw a sample of blood from your arm and it will be processed in the lab.
The Widal Test diagnoses typhoid fever by detecting specific antibodies, useful during suspected infections.

The widal test report includes the titre of antibodies against Salmonella Typhi and Paratyphi. The normal titre of S.Typhi and S.Paratyphi is considered to be less than 1:80
Antigen | Organism | Type | Normal Range | Interpretation |
---|---|---|---|---|
TO | Salmonella Typhi | O (Somatic) | ≤ 1:80 | Positive if titre is ≥ 1:160. No agglutination at 1:20 = Negative. |
TH | Salmonella Typhi | H (Flagellar) | ≤ 1:80 | Suggestive of infection if titre ≥ 1:160. No reaction at 1:20 = Clearly negative. |
AO | Salmonella Paratyphi A | O (Somatic) | ≤ 1:80 | High titres (≥ 1:100) may suggest Paratyphi A infection. |
AH | Salmonella Paratyphi A | H (Flagellar) | ≤ 1:80 | Positive if titre is significantly raised (≥ 1:100). |
BO | Salmonella Paratyphi B | O (Somatic) | ≤ 1:80 | Positive only if titre rises above 1:100. 1:20 = Negative. |
BH | Salmonella Paratyphi B | H (Flagellar) | ≤ 1:80 | Positive if ≥ 1:100. No agglutination = Negative. |
Typhoid fever is fever with rash and stomach pain caused by infection from Salmonella Typhi or Salmonella Paratyphi. They are bacteria that spread through contaminated food and water
Widal test is positive around 1 week after the fever. However a negative test does not rule out the infection. At times only blood cultures reveal typhoid fever.
We use tube agglutination technology for this test
Typhifast assay is faster and more accurate in some cases of typhoid fever.
Yes we have a typhoid fever profile that you can also consider for complete typhoid screening.
The normal range for Salmonella typhi O agglutinin in a Widal Test is typically less than 1:80, but this can vary depending on the laboratory and local endemic factors.
A positive Widal Test report for typhoid indicates the presence of significant levels of antibodies against the causative agent of typhoid fever, Salmonella typhi, suggesting a current or past infection.
A negative Widal Test report generally indicates the absence of significant levels of antibodies for Salmonella typhi or paratyphi, suggesting that the patient may not have a current or recent infection.
The Widal Test operates on the principle of detecting the presence of specific agglutinating antibodies against the O and H antigens of Salmonella typhi and paratyphi in a patient's serum, indicating a potential current or recent infection.
