How to Diagnose Typhoid Fever: Key Diagnostic Tests to Note


Typhoid fever is a bacterial infection caused by the bacterium Salmonella Typhi. It affects millions of people worldwide every year. This is why awareness and early detection of this bacterial infection are important. Here is all you need to know about typhoid fever:

How Does Typhoid Fever Spread?

Typhoid is a bacterial infection that spreads through contaminated food and water (with Salmonella Typhi). It is a common infection in many parts of the Indian subcontinent. When the bacteria pass through the intestinal walls, they reach the blood in a short time. The infection can spread to various organs, such as the liver, gallbladder, and bone marrow.

Common Symptoms of Typhoid Fever

  • Fever
  • Body ache
  • Weakness
  • Abdominal pain
  • Loss of appetite
  • Cough
  • Slow pulse rate

Important Tests for Typhoid Fever

Widal Test

A Widal test is one of the most common typhoid fever tests. It confirms the presence/absence of serum agglutinins or antibodies (O and H) in the blood. If a Widal test report is positive, it indicates the presence of a past bacterial infection in an individual.

Blood Culture

A blood culture test detects the S. Typhi bacteria in the blood. In this test, the person’s blood, stool, or urine sample is taken and isolated in an environment supporting bacterial growth. This culture is used for the diagnosis of typhoid fever in the first week of infection. 

Typhidot Test

The doctor may recommend a Typhidot test to a person if they suspect a typhoid infection. It is a rapid serological test that detects IgM and IgG antibodies in the body. These antibodies are produced to fight against typhoid-causing bacteria, so a higher count in the test report may indicate typhoid fever. 

Doctors can also order a fever panel test along with specific typhoid fever tests for proper diagnosis and treatment. A person can get these tests at a renowned medical laboratory for timely and accurate test reports. The best laboratories have trained medical professionals and phlebotomists for proper sample collection and testing. One can book these tests online and opt for home sample collection at an additional cost.
