Widal Test Report Format Download
What is Widal Test Report?
A Widal test report is a diagnostic document used to detect typhoid fever, caused by the bacterium Salmonella Typhi. The report outlines the results of the Widal test, which measures the presence of specific antibodies (O and H antigens) in a patient’s blood serum
The report typically includes:
- Patient Information: Name, identification number, and date of sample collection.
- Test Results: Indication of positive or negative results, and the antibody titers for each antigen.
- Clinical Interpretation: Explanation of the test results, potential pathogens identified, and clinical significance.
- Reference Ranges: Standard reference ranges for antibody titers.
- Recommendations: Suggested follow-up tests or further diagnostic steps.
This report helps healthcare professionals diagnose and manage typhoid fever effectively
Key Components of a Widal Test Report
Test Information: The physician’s contact information and the significance of the test for the patient’s health condition.
Analysis of the Results The clear and precise evidence of positive or negative results as well as an explanation of titers that are significant in each of the antigens, as well as identification of possible pathogens (Salmonella, Typhi, Paratyphi B, A, and C).
units and Reference Ranges Standard reference ranges for a variety of antibody types and units for reporting the titers of antibodies.
clinical significance and symptoms: Explains the clinical implications of rising or positive antibody titers as well as common symptoms that are associated with positive results.
Other Tests and Recommendations for Follow-Up Follow-up tests or examinations are suggested for confirmation and guidance on further steps in diagnosing the problem.
Quality Control, Methodology: A brief explanation of the Widal test procedure and the quality control measures that were implemented throughout the testing.
Limitations and Warnings The test’s explanation of limitations (e.g. false positives/negatives) and recommendations for the proper treatment for patients.
Clinical history and differential diagnosis It is important to provide the complete patient history to ensure a precise interpretation and mention of any possible diagnoses associated with paratyphoid or typhoid fevers.
Consulting and reporting Affirmation to consult with a medical professional for a thorough interpretation and contact details to discuss further or get clarification.
An adequately designed Widal test report is sure to convey transparency, accuracy, and efficient reporting of test results, helping healthcare professionals offer appropriate medical interventions and treatment for patients.

What do the results mean?
Interpreting the results of a Widal test involves understanding the significance of antibody titers to various antigens of Salmonella bacteria. Here’s what the results generally mean:
Understanding Widal Test Results
1. O Antigen (Somatic Antigen)
Negative Result: Titer < 1:20
Positive Result: Titer ≥ 1:60
A high titer indicates a current or recent infection with Salmonella Typhi or Salmonella Paratyphi.
2. H Antigen (Flagellar Antigen)
Negative Result: Titer < 1:20
Positive Result: Titer ≥ 1:60
A high titer suggests past infection or immunization against typhoid fever.
Interpretation
Low Titers: Results below 1:20 are generally considered negative and indicate no significant infection.
High Titers: Titers of 1:60 or higher are indicative of a significant infection, suggesting either a current or recent infection with the corresponding Salmonella strain.
Clinical Implications
Positive O Antigen: Indicates an active infection with Salmonella Typhi or Salmonella Paratyphi.
Positive H Antigen: Can indicate past infection or immunization, but also may support a diagnosis of typhoid fever when correlated with clinical symptoms.
Follow-Up Actions
Correlate with Symptoms: Positive results should be considered alongside the patient’s clinical symptoms and history.
Additional Testing: If positive, further confirmatory tests or repeated testing may be necessary for accurate diagnosis and treatment planning.
Limitations
False Positives/Negatives: Other conditions can sometimes lead to false positive or false negative results. It’s essential to interpret Widal test results in the context of the overall clinical picture.
