Increased Levels of S100A8/A9 in Patients with Peritonsillar Abscess: A New Promising Diagnostic Marker to Differentiate between Peritonsillar Abscess and Peritonsillitis

Table 1

PTA score: Addition of one point each for symptoms like halitosis, trismus, uvula edema, unilateral swelling of the arched palate, and S100A8/A9 levels in serum and saliva higher than the cut-off values results in a score with a range from 0 to 6. High S_PTA values are associated with an increased probability of PTA.

Symptoms	Points
Halitosis	1
Trismus	1
Uvula edema	1
Unilateral swelling of the arched palate	1
Serum S100A8/A9 > 2550 ng/ml	1
Saliva S100A8/A9 > 8180 ng/ml	1

0–2: acute tonsillitis/peritonsillitis; ≥3: peritonsillar abscess.
