Overview
Laboratory findings
Although the diagnosis of peritonsillar abscess may be made without the use of laboratory findings, the following nonspecific laboratory findings may be seen:[1][2][3][4][5]
- Complete blood count with differential
- This usually shows leukocytosis with neutrophilic predominance
- Serum electrolytes
- This is useful too in patients presenting with dehydration
- Gram stain, culture and sensitivity for sample after abscess drainage.
- Emperic therapy should be initiated and modified accordingly when results are ready.
- A routine throat culture for group A streptococcus.
