Typhoid fever is a bacterial infection caused by Salmonella typhi. It presents with symptoms like fever, abdominal pain, and diarrhea. Typhoid Diagnosis involves blood or stool tests. Timely treatment with antibiotics can lead to a favorable outcome.
Typhoid fever can be diagnosed through several different tests. Some of the common tests for typhoid diagnosis include:
| Test Name | Widal Test |
|---|---|
| Also Known As | Typhoid Serology Test |
| Purpose | Diagnosing and confirming typhoid fever infections |
| Sample | Blood |
| Preparation | No specific preparation needed |
| Procedure | Blood sample collection and analysis for antibody titers |
| Test Timing | Can be done at any time |
| Test Price (INR) Range | 300-800 |
| Result Value | Antibody titers for Salmonella typhi and Paratyphi |
| Normal Value | Negative or low antibody titers |
| Accuracy | Moderate to high |
| Interpretation | Rising antibody titers suggest recent or ongoing typhoid infection |
Diagnose and confirm typhoid fever infections with the Widal Test, which measures antibody titers for Salmonella typhi and Paratyphi.
| Test Name | Blood Culture |
|---|---|
| Also Known | Bacterial Culture |
| Purpose | Identifying and determining the presence of bacteria in the bloodstream |
| Sample | Blood |
| Preparation | None |
| Procedure | Blood sample collection and incubation to allow bacteria growth |
| Test Timing | Usually takes 1-2 days for results |
| Test Price (INR) | 1000-3000 |
| Result Value | Presence or absence of bacteria, specific bacteria identification |
| Normal Value | Negative for bacterial growth |
| Accuracy | High |
| Interpretation | Positive results indicate bloodstream infection requiring appropriate treatment |
A Blood Culture, also known as Bacterial Culture, is a diagnostic test that identifies the presence of bacteria in the bloodstream. It involves collecting a blood sample and incubating it to allow bacteria to grow.
| Test Name | Stool Culture |
|---|---|
| Also Known As | Fecal Culture |
| Purpose | Detecting bacterial, viral, and parasitic infections in the digestive system |
| Sample | Stool |
| Preparation | No specific preparation needed |
| Procedure | Collection of a stool sample and culturing it to identify potential pathogens |
| Test Timing | Depends on the specific test requested |
| Test Price (INR) Range | 500-1500 |
| Result Value | Identification of specific pathogens or growth of normal flora |
| Normal Value | Absence of pathogenic organisms or normal flora present in expected amounts |
| Accuracy | High |
| Interpretation | Presence of specific pathogens may indicate an infection requiring appropriate treatment |
A Stool Culture, also known as a Fecal Culture, is used to detect bacterial, viral, and parasitic infections in the digestive system.
| Test Name | Urine Culture Test |
|---|---|
| Also Known As | Urine C/S |
| Purpose | Detecting and identifying bacterial or fungal infections in the urinary tract |
| Sample | Urine |
| Preparation | Clean catch urine sample collected midstream to minimize contamination |
| Procedure | Plating the urine sample on culture media and incubating it to allow bacterial or fungal growth |
| Test Timing | Typically takes 24-48 hours for results |
| Test Price (INR) | 500-1500 |
| Result Value | Presence of specific bacteria or fungi, along with the number of colonies |
| Normal Value | No significant bacterial or fungal growth |
| Accuracy | High |
| Interpretation | Positive result indicates a urinary tract infection requiring appropriate treatment |
The Urine Culture Test, also known as Urine C/S, is performed to detect and identify bacterial or fungal infections in the urinary tract.
| Test Name | Blood Culture | Stool Culture | Urine Culture |
|---|---|---|---|
| Also Known As | Bacterial Culture | Fecal Culture | Urine C/S |
| Purpose | Detecting bloodstream infections | Identifying bacterial pathogens in the stool | Detecting urinary tract infections |
| Sample | Blood | Stool | Urine |
| Preparation | No specific | No specific | No |
| Procedure | Collection of blood sample and incubation for growth of microorganisms | Collection of stool sample and incubation for growth of microorganisms | Collection of urine sample and incubation for growth of microorganisms |
| Test Timing | Depends on laboratory | Depends on laboratory | Depends on laboratory |
| Test Price (INR) | 500-2000 | 500-1500 | 500-1500 |
| Result Value | Presence of bacterial or fungal growth | Presence of bacterial growth | Presence of bacterial growth |
| Normal Value | Absence of significant growth | Absence of significant growth | Absence of significant growth |
| Accuracy | High | High | High |
| Interpretation | Presence of growth indicates bloodstream infection | Presence of growth suggests bacterial infection | Presence of growth indicates urinary tract infection |
Detect bloodstream infections with Blood Culture, identify bacterial pathogens in the stool with Stool Culture, and detect urinary tract infections with Urine Culture.

Here are 7 Interesting Facts about Typhoid Fever.
Conclusion
Typhoid fever is a life-threatening bacterial infection spread through contaminated food and water. Prevention through good hygiene and vaccination is crucial, and prompt medical attention is necessary if symptoms develop to effectively manage and prevent the disease from spreading.

Typhoid fever is caused by the bacterium Salmonella Typhi, which spreads through contaminated food and water. The bacteria enter the body through the mouth and then travel to the intestines, where they can multiply and spread to the bloodstream.
The duration of typhoid fever varies, but it typically lasts for around 3-4 weeks without treatment. However, with proper treatment, including antibiotics and supportive care, symptoms can often be alleviated within a few days to a week.
In general, it is recommended to avoid milk and dairy products during typhoid fever as they can be difficult to digest and may aggravate diarrhea. However, some doctors may suggest consuming small amounts of low-fat milk or yogurt as a source of protein and to help maintain electrolyte balance.
It is not normal to have any level of typhoid fever as it is an infectious disease caused by the bacterium Salmonella Typhi. Even a low level of infection can be dangerous if left untreated. It is important to seek medical attention if you suspect you may have typhoid fever.
