The Simple Febrile Seizure CPG team concurs with the recommendation of the AAP (P. K. Duffner et al., 2011) not be performed as part of a routine evaluation of a simple febrile seizure. Specifically the AAP guideline states serum electrolytes, calcium, phosphorus, magnesium, blood glucose or a complete blood cell count “should not be performed in the routine evaluation of the child with a simple febrile seizure”. The recommendation is based on evidence from observational studies. In 2012, Teran, Medows, Wong, Rodriguez, & Varghese, 2012) evaluated the usefulness of obtaining a CBC in children with a simple febrile seizure. They report 134/182 (73%) had a normal CBC, 42/182 (23%) had leukocytosis, and 6/182 (4%) had leucopenia. We value identifying the source of the fever, and treating the cause of the fever appropriately.
