Overview
Laboratory Findings
Labortary tests may help determine the risk factors complications of ischemic stroke. Blood tests which may be performed include:
Blood test
|
Test result
|
Rationale
|
Complete blood count
|
|
- May suggest underlying infection
- Increased risk of thrombotic event
- May increase the risk of bleeding in pateints eligible for thrombolytic therapy
|
Lipid profile
|
|
- May increase the risk of thromboembolic event
|
PT/APTT/INR
|
|
- May increase the risk of bleeding in patients eligible for anticoagualant therapy
- May suggest underlying coagulation disorder
|
BUN/Creatinine
|
- Increased BUN and creatinine
|
- Mild to moderate renal dysfunction is an independant risk factor for ischemic stroke
- May be associated with poor prognosis in patients with ischemic stroke
|
Serum homocysteine level
|
- Increased levels of serum homocysteine levels
|
- May be associated with increased risk of thromboembolic event
|
Basic metabolic panel
|
- Increased or decreased serum NA2+, K+, Ca2+
|
- May mimic or complicate patients with ischemic stroke
|
HbA1C
|
- Increased levels of HbA1c
|
- May suggest control of diabetes in past few months
- Increased levels associated with increased risk of ischemic stroke
- May be associated with poor prognosis in patients with ischemic stroke
|
Blood glucose levels
|
- Increased or decreased levels of blood glucose
|
- Hyperglycemia is associated with poor prognosis of ischemic stroke
- Hypoglycemia may complicate or mimic patients with ischemic stroke
|
Cardiac enzymes
|
- Increased serum levels of Trop I, Trop T, CK-MB
|
- May suggest ongoing myocardial ischemia
|
Pregnancy test
|
|
- Rule out pregnancy in all female patients with ischemic stroke since t-PA is a class C agent
