Differentiating Tonsillitis From Glandular Fever: Is the Lymphocyte–White Blood Cell Count Ratio Any Help?—Reply

Arch Otolaryngol Head Neck Surg. 2007;133(9):952. doi:10.1001/archotol.133.9.952-b

We thank Smale and coauthors for their interest in our recently published article on the lymphocyte–white blood cell count ratio in patients with glandular fever and tonsillitis. We realize that using the Monolatex test as a criterion standard skewed our results; however, financial constraints precluded us from using serologic tests as a reference point. The article cited by Smale and colleagues refers to a sensitivity of 93.9% and a specificity of 98.3%.1 These figures were arrived at only after resolution of discrepant results between the 3 kits tested.
