What is a Widal Test (Tube Method)?
The Widal test, also known as the Widal tube test, is a specialised serological test used to detect typhoid and enteric fever—both of which are caused by the bacteria Salmonella typhi and Salmonella paratyphi. These bacteria typically spread through contaminated food or water.
- In India, the Widal test tube method is widely performed when a patient presents with persistent high fever, abdominal discomfort, headache, or loss of appetite. The full form of the Widal test is the Widal Agglutination Test. In simple terms, this test detects specific antibodies produced by the immune system to fight these bacteria.
- A positive Widal tube test can help confirm an active or recent infection, allowing your doctor to begin appropriate treatment promptly. This test is particularly valuable to distinguish typhoid fever from other conditions with similar symptoms, such as malaria or dengue.

What is the Widal Test (Tube Method) Price?
Understanding the Widal test tube method price helps you plan your diagnostic expenses wisely. The cost may vary due to multiple factors:
- City-Based Pricing: The Widal tube test price may differ from city to city. For example, in major metros like Delhi or Mumbai, you may notice a slightly higher rate than in smaller towns due to higher operational costs. Always compare the typhoid test price in your city for better planning.
- Demand for the Test: The Widal test price or Widal test cost can fluctuate based on demand. During seasons when typhoid cases peak, there may be a slight increase in the cost.
- Comprehensive Inclusions: Some labs offer combined packages with other related tests such as a complete blood count (CBC) or liver function test (LFT). Such bundles may cost more than a standalone Widal tube test, but they offer a fuller diagnostic picture.
- Laboratory Differences: Different laboratories might have different pricing structures for their services due to variations in quality, expertise, and technology used. Always compare prices and reviews before choosing a lab.
- Discounts and Promotions: Often, medical labs offer discounts and promotions on the Widal blood test price. You could save a considerable amount with such offers on Widal test cost.

What is the Purpose of the Widal Test (Tube Method)?
The Widal test is used to confirm suspected cases of typhoid fever. The following are some critical reasons for which the Widal test is done:
- Early Detection: The Widal test plays a crucial role in the early detection of typhoid fever, which enhances treatment effectiveness.
- Diagnosis Confirmation: This test aids in confirming the presence of S. typhi or S. paratyphi bacteria in your body.
- Symptom Monitoring: It helps monitor symptom progression, guiding doctors to adjust treatment protocols as necessary.
- Prevents Misdiagnosis: Since the symptoms of typhoid can resemble other illnesses like dengue or malaria, the Widal test helps avoid misdiagnosis.
- Informs Vaccination Decisions: If you've been vaccinated against typhoid in the past, this test helps determine if you still have protective immunity.
It's, however, essential to note that the Widal tube test alone may not provide a definitive diagnosis. It's usually ordered alongside other tests for comprehensive results.
Who Should Get a Widal Test (Tube Method) Done?
This test is recommended for individuals who exhibit the following signs and symptoms:
- Persistent High Fever: Typhoid fever often presents itself with an ongoing high temperature that does not alleviate with typical fever medications.
- Abdominal Pain: Experiencing discomfort or pain in the abdominal region could be a tell-tale sign of typhoid fever.
- Headaches: Regular or severe headaches may indicate a possible infection.
- Loss of Appetite: A significant reduction in hunger or interest in food can be another symptom to look out for.
Anyone recently exposed to potentially contaminated water or food sources should also consider a Widal tube test, especially in areas with poor sanitation. If you notice these symptoms, consult your doctor for timely diagnosis and care.
Components of a Widal Test (Tube Method)
Understanding the test’s structure helps in accurate Widal test interpretation. Understanding the various components of the Widal test, particularly the tube method, is essential not only for medical professionals but also for patients. Let's now discuss these components in detail:
- Salmonella Typhi 'O': This is an essential part of the Widal test procedure. It focuses on detecting the presence of specific 'O' antibodies that react against the bacteria causing typhoid, i.e., S. typhi.
- Salmonella Typhi 'H': This second component aims to identify another type of antibody, 'H'. These are produced by your immune system in response to an infection with S. typhi.
- S. Paratyphi A 'H': This component targets another subtype of Salmonella called paratyphi A. The detection of 'H' antibodies against this bacterium indicates a possible paratyphi A infection.
- S. Paratyphi B 'H': This last key component looks for 'H' antibodies reacting against a different subtype known as paratyphi B.
These four tests under the Widal tube method serve a crucial purpose. They help in determining if a person has typhoid or paratyphoid fever based on the specific antibodies present in their blood.
Understanding these components can help you appreciate how intricate your body's response to infections is and why timely testing like the Widal test is so vital in disease management.
Understanding the Widal Test (Tube Method) Report
The test results are expressed in titres such as 1:80 or 1:160. But what does Widal test 1:160 mean? Let's know what it means below:
Note: The results of the test are typically reported as titres (e.g., 1:80, 1:160) indicating the dilution of serum at which antibodies against specific antigens are detectable. Also, the values of this test can vary depending on the laboratory, timing of sample collection, vaccination status, and presence of other or previous infections.

S. Paratyphi B 'H'
Preparation and Procedure for the Widal Test (Tube Method)
Before undergoing the Widal tube test, it's crucial to understand the Widal test preparation and procedure involved in ensuring accurate results. In the following subsections, you will delve into detail on how you can prepare for it.
A. How is the Widal Test (Tube Method) Done?
The Widal test procedure is quite straightforward. It involves the following steps:
- The phlebotomist will first cleanse your arm with an antiseptic wipe.
- A tourniquet is applied to your upper arm to make your veins more visible.
- Using a syringe, a small sample of blood is drawn from your vein.
- This sample is then sent to the lab where it's placed in tubes containing different dilutions of antigens specific to typhoid-causing bacteria.
- If you have been infected with this bacteria, your blood will react with these antigens, leading to a visible agglutination (clumping together) that can be observed under a microscope.
