Answer

Laboratory studies that may be helpful include the following:

  • Stain or culture of nodal tissue - This can help diagnose atypical tuberculous adenitis
  • Complete blood count (CBC) - Results are nonspecific, but leukocytosis with left shift may occur with strangulation
  • Electrolyte, blood urea nitrogen (BUN), and creatinine levels - It is advisable to assess the hydration status of the patient with nausea and vomiting; these tests are rarely needed for patients with hernia except as part of a preoperative workup
  • Urinalysis - This can help narrow the differential diagnosis of genitourinary causes of groin pain in the setting of associated hernias
  • Lactate levels - Elevation may reflect hypoperfusion; a normal level does not necessarily rule out strangulation
