My wife is suffering from high fever for last 4 days .. NS1 antigen & maleria test are negative . Platellets count was 80000 on Tuesday and then became 1,20000 on wednesday . But till she is suffering from fever between 102 to 103. Is it a Viral or Thypoid fever
HIT hanks for posting your query to Chat Doctor See NS1 test could be negative if done after 3 days of fever, so I advise getting IGM Dengue Antibodies to check if Dengue fever is there or not.  It is unlikely for Typhoid fever to cause low platelet but sometimes typhoid fever co-exists with Viral fever and in that case Platelet count can be low. So I advise you to get IGM Ty phi Dot to check for Typhoid fever.  I also advise getting Urine routine test. Repeat platelet count everyday till it reaches normal value.  The possibility of viral fever is very high and if temperature is of 102-103 then better you admit her to a hospital. Hope this information was useful to you. Any clarifications feel free to ask.
