Answer

Prior to initiating therapy, consider obtaining some or all of the following laboratory studies:

  • Complete blood count (CBC) with differential, liver panel, renal panel with electrolytes and glucose, calcium, magnesium, phosphorus, and urinalysis with microscopic examination

  • Metabolic workup, including glucose, liver panel, serum lactate and pyruvate, plasma ammonia, serum and urine amino acids, urine organic acids, and serum biotinidase

  • Blood, urine, and cerebrospinal fluid cultures if an infection is suspected

  • Cerebrospinal fluid analysis for cell count, glucose, protein, bacterial and viral culture, lactate, pyruvate, and amino acids
