What your results can mean
Reading your report
Rapid typhoid antibody tests can give false results, so a blood culture is more reliable; discuss your result with your doctor.
If the result is outside the usual range
A positive IgM can suggest a recent typhoid infection, while IgG alone can reflect past exposure. These rapid tests can give false positives and negatives, so blood culture remains the main test.

Questions about this test
What are Typhidot and Enterocheck?
They are brand names for rapid card tests that detect antibodies against typhoid bacteria. They give a quick result but are less reliable than a blood culture.
Should antibiotics be started on a rapid typhoid result alone?
Your doctor decides based on symptoms, examination and tests together. A blood culture taken before antibiotics helps guide treatment.
How can I lower my risk of typhoid?
Drink boiled or treated water, eat freshly cooked food and wash hands well. A typhoid vaccine is also available.
