Can a blood test detect a stroke?

Stroke Refers to Cerebral Infarction

Blood examination typically refers to blood tests. Cerebral infarction cannot be detected solely through blood tests. Blood tests are conducted during cerebral infarction primarily because they can reflect relevant indicators associated with the condition, such as blood glucose, blood lipids, platelet count, and hemoglobin levels. However, these tests serve as an auxiliary diagnostic tool.

Cerebral infarction is a disease caused by ischemic necrosis or softening of localized brain tissue. Blood tests alone cannot serve as a basis for diagnosing cerebral infarction. Imaging examinations are primarily used, including cranial CT scans and cranial MRI, which can detect the area and severity of cerebral infarction. For a more detailed examination, angiography can also be performed. It is the primary method for examining cerebral blood vessels, revealing conditions like stenosis and occlusion of major cerebral arteries, as well as other vascular abnormalities such as vasculitis and moyamoya disease.

If cerebral infarction is suspected, prompt medical attention is necessary. Imaging examinations should be conducted in collaboration with medical professionals. If cerebral infarction is confirmed, early treatment is crucial.
