Introduction to S Typhi O

Have you been feeling weak and feverish for a long time, along with severe abdominal pain? It could be due to typhoid fever, which is caused by being infected by the Salmonella Typhi bacteria.

Typhoid, also known as enteric fever, can deteriorate one’s health significantly, which is why it is important to get tested if there are any symptoms of typhoid. If the condition goes undiagnosed, one can experience life-threatening complications.

Thankfully, The Widal Test is available to diagnose whether you are suffering from typhoid or not. The Widal test has two types: the s typhi O test and the s typhi H test. The s typhi O test helps to identify whether the bacteria is active.

The test helps doctors identify the severity of the condition and provide treatments accordingly. If you or anyone around you has symptoms of typhoid fever and wants to get tested, you can book your test with Redcliffe Labs and get tested from the comfort of your home.

What is the Purpose of the Widal S Typhi O Test?

The Widal test is a serological test used to diagnose enteric fever, commonly known as typhoid fever, caused by the bacteria Salmonella enterica serotype Typhi. The test specifically detects the presence of antibodies in a patient's serum against the O (somatic) and H (flagellar) antigens of Salmonella Typhi.

The Widal test's primary purpose is to help diagnose typhoid fever in patients presenting with symptoms such as prolonged fever, headache, gastrointestinal disturbances, and malaise, especially in areas where the disease is endemic. The test measures the levels of antibodies (anti-O and anti-H) in the blood, which typically rise during infection. 

The "O" antigen is a component of the bacterial cell wall and is associated with the polysaccharide structure of bacteria. An elevated titer of anti-O antibodies indicates an active infection or recent exposure, suggesting acute typhoid fever. 

Despite its usefulness, the Widal test has limitations, including false positives due to previous vaccinations, infections with related bacteria, or chronic carriers. Therefore, it is often used in conjunction with other clinical findings and diagnostic tests, such as blood cultures, to confirm the presence of Salmonella Typhi.

Preparations Before the Widal S Typhi O Test:

No special set of rules must be followed before taking the S typhi O blood test. However, these are some basic guidelines to be followed:

  • You are not required to fast before taking the double marker test, but if your health requires it, talk to your physician about any special dietary requirements.
  • If you are pregnant, you might be taking any medication or supplements. It is important to inform your doctor about that as well. You do not need to panic in such situations; if they think there is an issue, they will also tell you about the solution. 
  • It is a blood test, so avoiding any workouts or yoga before taking the test is always recommended.
  • It is advised not to smoke or drink alcohol before taking the test because it may alter the test results.

If you follow these basic guidelines before taking the test and keep your physician in the loop, you are ready.

The procedure for the Widal S Typhi O test:

This S Typhi O test is like any other blood test, and it does not take more than 5-10 minutes for the phlebotomist to take the blood sample. The procedure for getting the test is as follows;

  • The phlebotomist, on arrival, ties a band around your arm.
  • They tell you to make a fist so the veins are properly visible.
  • They disinfect the area from which the blood is to be drawn.
  • Then, a thin, sterile needle is inserted into the vein to draw blood, and after the needle is removed, a bandage is put on the punctured area.
  • After drawing the blood, they put it in a vial, seal it, and label it.
  • This vial is then taken to the laboratory to be tested.

Remember that the punctured area may have a stinging sensation for two days. If the pain lasts longer than two days or is significantly severe, consult a doctor.

Symptoms of Typhoid:

Typhoid fever is caused by the bacteria called Salmonella typhi. The bacteria causes multiple issues in the body, but the symptoms do not occur before 1-3 weeks of getting infected by the bacteria. It takes a long time to know if you have typhoid fever, so getting yourself tested as soon as you start seeing the symptoms is recommended. Some of the symptoms to look for are: 

  1. Prolonged fever: Often above 39-40 degrees, lasting over a week.
  2. Weakness and fatigue.
  3. Headache.
  4. Stomach pain and discomfort.
  5. Loss of appetite.
  6. Diarrhea or constipation: Diarrhea is more common in children, while constipation is more common in adults.
  7. Rash: Flat, rose-colored spots, particularly on the abdomen and chest.
  8. Muscle aches.
  9. Chills and sweating.
  10. Weight loss.
  11. Dry cough.

In severe cases, there may be complications such as intestinal bleeding or perforation, which can be life-threatening. If you suspect typhoid fever, seek medical attention immediately to get proper treatment.

Preventive measures for Typhoid:

Prevention is better than cure, so you must be careful not to get infected by Salmonella Typhi. Typhoid can cause major weakness in your body, and it can take a very long time to recover, so it is recommended to take preventive measures. Some things that you can do to keep yourself away from the infection are:

  1. Vaccination: 

There are two types of vaccines available:

  • Oral vaccine (live, attenuated): Requires multiple doses.
  • Injectable vaccine (inactivated): A single shot, often recommended for travelers to endemic areas. 
  1. Safe Drinking Water:
  • Drink only bottled or boiled water.
  • Avoid ice unless made from safe water.
  1. Good Sanitation and Hygiene:
  • Wash hands frequently with soap and clean water, especially before eating and after using the toilet.
  • Avoid street food and ensure food is cooked thoroughly and served hot.
  1. Food Safety:
  • Eat only well-cooked food.
  • Avoid raw fruits and vegetables unless you can peel them yourself.
  • Avoid seafood that may come from contaminated water.
  1. Avoid Risky Beverages:
  • Avoid raw milk and products made from raw milk.
  • I prefer hot beverages like tea and coffee, which are generally safe.
  1. Travel Precautions:
  • Be cautious about where and what you eat when traveling in areas where typhoid fever is common. 

If you think that you might be suffering from typhoid, it is important to get tested and consult with a doctor as soon as possible. More than anything, it is important to follow the guidelines provided by your doctor; they provide treatments based on your medical history, so you need to consult with them before making any changes in your lifestyle or medication.
