The maximum days for obtaining the report for the WIDAL Test By Tube Agglutination is typically 3-5 days. However, this may vary depending on the laboratory and the specific circumstances of the test.

What are the prerequisites for the test WIDAL Test By Tube Agglutination

  • 1. Blood sample: A blood sample is required for the Widal test. The sample should be collected in a sterile container by a healthcare professional.
  • 2. Fasting: The patient may be required to fast for a certain period of time before the test to ensure accurate results.
  • 3. Medical history: The patient may need to provide information about their medical history, including any recent illnesses or medications they are taking.

  • 5. Informed consent: The patient should be informed about the purpose of the test, its potential risks, and how the results will be used before giving consent to undergo the test.

What are the measure values for the test WIDAL Test By Tube Agglutination

  • Salmonella Typhi O: ≥ 1:80
  • Salmonella Typhi H: ≥ 1:160
  • Salmonella Paratyphi AH: ≥ 1:80
  • Salmonella Paratyphi BH: ≥ 1:80

What does this test WIDAL Test By Tube Agglutination identify?

WIDAL Test By Tube Agglutination

The WIDAL test by tube agglutination is a diagnostic test used to identify certain types of bacterial infections, specifically typhoid and paratyphoid fevers. This test detects the presence of antibodies in the blood that are produced in response to the Salmonella bacteria that cause these infections.

During the test, the patient's blood is mixed with a series of antigens that are specific to Salmonella typhi and Salmonella paratyphi. If the patient has been infected with these bacteria, their blood will contain antibodies that will react with the antigens, causing visible clumping or agglutination in the test tubes.

Interpreting the results of the WIDAL test involves measuring the degree of agglutination that occurs in each tube. A positive result indicates that the patient has been exposed to the Salmonella bacteria and has developed antibodies against them, suggesting a current or recent infection.

It is important to note that the WIDAL test is not always accurate and can produce false positive results. Therefore, it is often used in conjunction with other diagnostic tests to confirm a diagnosis of typhoid or paratyphoid fever.

Why is this test WIDAL Test By Tube Agglutination taken?

WIDAL Test By Tube Agglutination

Why is this test taken?

The WIDAL test is a serological test used to diagnose typhoid fever caused by Salmonella typhi or other related Salmonella species. The test is based on the principle of agglutination, where antibodies in the patient's serum react with specific antigens present on the surface of the Salmonella bacteria.

The WIDAL test is taken to:

  • Confirm the diagnosis of typhoid fever in patients presenting with symptoms such as high fever, abdominal pain, and gastrointestinal disturbances.
  • Monitor the response to treatment in patients with typhoid fever.
  • Identify carriers of Salmonella typhi who may be asymptomatic but can still spread the infection to others.

It is important to note that the WIDAL test is not always conclusive and may require additional tests for confirmation. Interpretation of the results should be done by a healthcare professional based on the clinical presentation of the patient.
