When a higher cutoff point is used to define an abnormal number of atypical lymphocytes, the sensitivity decreases (i.e., more false-negative diagnoses) and the specificity increases (i.e., fewer false-positive diagnoses). Another trial found no significant benefit from the use of ranitidine (Zantac) in patients with infectious mononucleosis.23, Corticosteroids have been advocated for the treatment of patients with infectious mononucleosis,8 and some early studies24,25 seemed to show a benefit from these agents with regard to normalization of temperature and laboratory values. government site.
