    What is a Widal Test ?

    Introduced by F. Widal in 1896, the Widal test is a blood test that measures antibody titres to diagnose typhoid or paratyphoid fever (collectively as enteric fever). Antibody titres assess the immune response of the body by measuring particular antibodies in the blood in reaction to antigens (foreign substances). The Widal test detects antibodies against the O and H antigens of Salmonella Typhi and the H antigens of Salmonella Paratyphi . The test uses a suspension containing killed Salmonella Typhi bacteria as the antigen to identify typhoid fever in febrile patients. Thus, those with symptoms of enteric fever may benefit from a Widal test.

    Given its role in diagnosing enteric fever, the Widal test can be a critical diagnostic tool aiding in timely detection and treatment. Therefore, consider getting a Widal test in Noida today, if you live in Noida and are experiencing symptoms of enteric fever.

    Widal Test (Slide Method) Parameters

    The Widal test, an agglutination test, finds cell clumping brought on by certain antibodies (agglutinins) in the blood interacting with particular antigens. These antibodies target two primary antigens of Salmonella Typhi : the O antigen and the H antigen. The test also includes the H antigens of Salmonella Paratyphi . By detecting these antibodies, the test helps diagnose enteric fever by indicating the body's immune response to these bacterial infections.

    The Widal test includes four parameters that represent the antibody titre levels against the bacteria responsible for enteric fever. The parameters include:

    • Salmonella Typhi O (TO)

    • Salmonella Typhi H (TH)

    • Salmonella Paratyphi A, H (AH)

    • Salmonella Paratyphi B, H (BH)

    Widal Test (Slide Method) Preparation

    Consider the following factors, before booking the Widal test in Noida:

    Prerequisites

    Fasting is not required for the Widal test.

    Best Time to Get Tested

    You can get the Widal test at any time throughout the day.

    Who Should Get a Widal Test

    If someone has been in a high-risk area for typhoid or paratyphoid fever and is experiencing headache, fever, fatigue, and gastrointestinal issues (constipation, diarrhoea, or abdominal pain), they should consider getting a Widal test.

    Cautions Before Taking the Widal Test

    There are no special precautions necessary for this test.

    Why Take a Widal Test ?

    The incubation period for typhoid bacteria typically ranges from 6 to 14 days, although it can extend to 30 days. This is the interval of time between the start of symptoms and bacterial infection. For paratyphoid bacteria, the incubation period ranges from 1 to 10 days. Generally, during the course of 3 to 4 days, symptoms often become worse.

    A doctor might order a Widal test if you have symptoms of typhoid fever. Similar, but milder, symptoms occur with paratyphoid fever. These signs and symptoms include:

    • High fever or chills

    • Constipation

    • Diarrhoea

    • Feeling unwell, weak, or sick

    • Headache

    • Extreme fatigue

    • Pain in the abdomen

    • Sweating

    • Blood in the stool

    • Sore throat and persistent cough

    • Bleeding from the nose

    • Weight loss

    • Loss of appetite

    • Red rash on the chest and abdomen

    • Confusion or hallucinations

    • Difficulty in concentrating

    • Decreased heart rate

    • Poisoning of blood

    • Enlarged spleen or liver

    Please note: Even with vaccination, 20–50% of individuals may still contract typhoid upon exposure, indicating incomplete immunity.

    A Widal test might be suggested for those at increased risk, including:

    • People in close proximity to an infected person.

    • Young children, who are more at risk for these diseases than adults.

    • Travellers to regions where typhoid and paratyphoid are widespread, such as India, Bangladesh, the Middle East, and Africa.

    Widal Test Results & Interpretation

    Below is a breakdown of the results of the Widal test:

    TypeAntibodyTitreInterpretation
    Salmonella TyphiTO<1:80Negative
    Salmonella TyphiTH<1:80Negative
    Salmonella ParatyphiAH<1:80Negative
    Salmonella ParatyphiBH<1:80Negative

    Interpretation

    Titres below 1:80 are considered negative, indicating no infection is present.

    Titres at or above 1:80 are generally seen as positive, though this threshold may differ across various populations and regions. A rising titre, identified through multiple samples taken at 4- to 6-day intervals after disease onset, is more significant than just one high titre. To reach a final diagnosis, test results should be correlated with the patient’s medical history.

    Limitations

    Patients who have been vaccinated against typhoid may show elevated antibody titres, which could lead to false-positive results. Similarly, individuals with past infections or vaccinations may also have misleading results.

    Agglutinins generally appear by the end of the first week of infection, so blood samples taken earlier might produce negative results.

    Though the serological findings of this test are important, they should not replace culture-based methods for identifying the causative organisms. Culture and biochemical tests should be performed to recover and identify the pathogens.

    FAQs on Widal Test in Noida

    A false-negative outcome in the Widal test implies no antibodies are detected when they are present, often due to testing too early. On the other hand, a false-positive result may suggest antibodies are present, potentially influenced by previous infections or vaccinations.

    The Widal test, a type of blood test for typhoid, detects the presence of antibodies in the blood against specific antigens of Salmonella bacteria, especially Salmonella Typhi and Salmonella Paratyphi . It helps in diagnosing enteric fever, including typhoid and paratyphoid fever, by indicating the body's immune response to these infections.

    No, fasting is not recommended for the Widal test or Typhoid test at home.

    Yes, Orange Health Labs offers the convenience of scheduling home sample collection for the Widal Blood test or Typhoid Blood test, with samples collected within 60 minutes of booking, based on available slots.

    The risk involved in a blood test is minimal. You may experience mild discomfort at the needle puncture site during sample collection, but it is short-lived.

    There is no standard 'normal' range for the Widal test. Titres below 1:80 are typically classified as negative, whereas titres of 1:80 or higher may suggest an infection. Nevertheless, interpretation varies depending on clinical factors and the prevalence of the disease in the area.

    After your sample is collected, expect to receive your results within 6 hours via WhatsApp and the app if you are in Noida. This time may vary in other cities.

    How frequently you undergo Widal testing depends on your doctor's recommendation. If you have been diagnosed with typhoid or paratyphoid fever, your doctor might advise undergoing this test every 2 weeks, adjusted according to your clinical condition and symptoms.

    Parameters in the Widal test encompass antibody titres targeting specific antigens of Salmonella bacteria, such as the O and H antigens of Salmonella Typhi , and the H antigens of Salmonella Paratyphi .

    The Widal test identifies antibodies against Salmonella bacteria, contributing to the diagnosis of both typhoid and paratyphoid fever.

    Serum and antigen are combined on a slide in the Slide method, whereas the Tube method mixes them within test tubes.
