If certain patient is suspected to be suffering from typhoid. Which diagnostic technique will you recommend for its detection?

Options

A. ELISA
B. WIDaL
C. MRI
D. CT scan

Answer

To determine if a patient is suffering from typhoid fever, the following steps can be taken:

1. **Identify Symptoms**: First, gather information about the patient's symptoms. Common symptoms of typhoid include prolonged fever, fatigue, headache, nausea, abdominal pain, and diarrhea or constipation.

2. **Collect Samples**: For diagnosing typhoid, you will need to collect biological samples from the patient. The most common samples used are blood, stool, or urine.

3. **Perform the Widal Test**: The Widal test is a serological test that detects the presence of specific antibodies (O and H antigens) against the bacteria Salmonella typhi in the collected samples. This test is specifically designed for diagnosing typhoid fever.

4. **Interpret the Results**: After performing the Widal test, analyze the results. A significant rise in antibody titers in paired sera or a high titer in a single sample can indicate an active infection.

5. **Consider Other Tests if Necessary**: If the Widal test results are inconclusive, other diagnostic methods such as blood cultures can be performed to confirm the presence of Salmonella typhi.

In conclusion, the recommended diagnostic technique for detecting typhoid fever is the Widal test.
