When should I repeat the Widal test after typhoid treatment?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

Before 20 days, I was typhoid positive. Then, I had Monocef 1 g injection once a day for seven days and then I had Zanocin 400 mg tablet once a day for seven days. Now, I am on Paraxin 500 three times a day and still I have some headache.

My current Widal test report is as follows. Typhi O 1:160, Typhi H 1:80, Typhi AH 1:40, and Typhi BH 1:40. Please tell me when I should repeat my test to know whether I am typhoid positive or negative.

Kindly help.

Hi,

Welcome to icliniq.com.

I can understand your concern.

Widal test in typhoid remains positive for up to a month, and so there is no need to repeat it as you will get it positive result even if typhoid is cured. We say that typhoid is cured when there is no fever for three consecutive days. There is no need to take Paraxin (Chloramphenicol) as it causes more weakness due to typhoid.

Please consult your doctor, discuss with him or her, and stop the medicine with consent. Take some rest and drink glucose three times a day for one week. Do not worry about the report.

I hope that this answers your query.

Kindly follow up if you have more doubts.

Thank you.
