🔆How is Typhoid fever diagnosed

📍Widal test and it's alternatives

Widal Test:

✅It is a test done for diagnosing typhoid fever.

✅Typhoid fever, also known as enteric fever, is a bacterial infection caused by the bacterium Salmonella Typhi, and it is commonly spread through contaminated food or water.

✅The symptoms mimic those of malaria, dengue, influenza, and typhus, to name a few, making it difficult to diagnose without proper testing.

✅The widal test is a serological test that detects antibodies against the bacteria in a patient’s blood sample, indicating whether or not they have been infected with the bacteria.

📍Limitations:
✅A single positive Widal test report doesn’t necessarily mean a typhoid infection is present, and a negative report doesn’t confirm the disease’s absence
✅The reagents used in the Widal test to reveal the presence of various antibodies can cross-react with antibodies produced against infections by other bacteria,
