Overview

Laboratory findings

Blood test Test result Rationale
Complete blood count and platelet
BMP/Osmolarity
  • Increased or decreased serum NA2+, K+, Ca2+
  • Change in osmolarity
PT/APTT/INR
  • Increased PT/APTT/INR
BUN/Creatinine
  • Increased BUN and creatinine
  • May be associated with poor prognosis in patients with intracerebral hemorrhage and hematoma expansion
Toxicology screen/Serum alcohol level
  • Increased levels of serum
HbA1C
  • Increased levels of HbA1c
Blood glucose levels[1]
  • Increased or decreased levels of blood glucose
Cardiac enzymes
  • Increased serum levels of Trop I, Trop T, CK-MB
  • Elevated Trop T levels are associated with poor prognosis
  • May suggest ongoing myocardial ischemia[2]
Pregnancy test
  • Serum and urine B-HCG
  • Rule out pregnancy in all female patients with hemorrhagic stroke
