Blood Test Confirming Typhoid Fever
Learn which blood test confirms typhoid fever, including details on the Widal test, Typhi IgM/IgG, and blood culture for accurate diagnosis.
Typhoid fever is a serious bacterial infection caused by Salmonella typhi. It spreads through contaminated food and water and can lead to high fever, stomach pain, and weakness if left untreated. A blood test is one of the most reliable ways to confirm typhoid fever. If you or a loved one is experiencing symptoms, getting tested early can help in starting the right treatment quickly.
What is Typhoid Fever?
Typhoid fever is an infection caused by the Salmonella typhi bacteria. It spreads through contaminated food or water, especially in areas with poor sanitation. Once inside the body, the bacteria multiply in the intestines and bloodstream, leading to symptoms like high fever, headache, and digestive issues.
Without proper treatment, typhoid can cause severe complications, including intestinal bleeding or perforation. Early diagnosis through a blood test is crucial for effective treatment.
Common Symptoms of Typhoid Fever
Typhoid symptoms usually appear 1-3 weeks after exposure and may include:
High fever (often rising gradually)
Headache and body aches
Weakness and fatigue
Stomach pain and loss of appetite
Diarrhoea or constipation
Rose-colored spots on the chest or abdomen (in some cases)
If you notice these symptoms, especially after consuming contaminated food or water, consult a doctor and get tested.

How a Blood Test Confirms Typhoid Fever?
A blood test is one of the most accurate ways to diagnose typhoid fever. Here’s how it works:
1. Widal Test
Checks for antibodies against Salmonella typhi.
A positive result (high antibody levels) suggests infection.
Sometimes, a second test is needed after a few days to confirm.
2. Blood Culture Test
A small blood sample is taken and tested for bacteria growth.
Considered the gold standard for typhoid diagnosis.
Results take 2-3 days but are highly reliable.
3. Typhidot Test
A rapid test that detects IgM and IgG antibodies.
Provides results within a few hours.
Your doctor will recommend the best test based on your symptoms and medical history.
Treatment and Recovery
If diagnosed early, typhoid fever can be treated effectively with:
Antibiotics: The primary treatment to kill the bacteria.
Hydration & Nutrition: Drinking plenty of fluids and eating easily digestible foods helps recovery.
Rest: Essential for regaining strength.
Important: Always complete the full course of antibiotics, even if you feel better, to prevent relapse.
Prevention Tips
Typhoid can be prevented with simple precautions:
Drink clean, boiled, or filtered water.
Wash hands thoroughly before eating.
Avoid raw or undercooked food, especially street food.
Get vaccinated if travelling to high-risk areas.
When to See a Doctor?
If you or someone you know has:
Persistent high fever
Severe stomach pain
Prolonged weakness or dehydration
Don’t delay—consult a doctor immediately. Early testing and treatment can prevent complications.
Conclusion
Typhoid fever is a serious but treatable condition. Recognising symptoms early and getting a blood test can help in quick recovery. By following hygiene practices and staying cautious with food and water, you can reduce the risk of infection. If you have any concerns, don’t hesitate to reach out to a healthcare provider.
