Beside above, what is the modified Centor score? The Modified Centor Score (also known as the McIssac Score or the McIssac Modification of the Centor Score) helps predict the probability of streptococcal pharyngitis by taking into consideration risk factors such as patient's age, symptoms, and physical exam.
