Serum Index Calculated from Sensory and Motor Function Scores (e.g., for Stroke or Neurological Assessment)

What This Test Measures

The test does not measure a single blood component directly but instead calculates an index derived from standardized scores for sensory perception and motor function. These scores are typically gathered through clinical exams by healthcare providers.

Why It’s Ordered

Your doctor may order this test if you’ve experienced neurological symptoms like weakness, numbness, or difficulty moving—common signs of stroke, brain injury, or other neurological disorders.

How the Test Works

No blood draw is required for this test. Instead, a healthcare professional evaluates your ability to feel sensations (e.g., touch, pain) and perform movements (e.g., muscle strength, coordination) in specific areas of your body. Scores from these assessments are combined to generate the index.

What to Expect Before the Test

No special preparation is needed. You may be asked to sit or lie down while the provider tests your reflexes, strength, and sensation in your arms, legs, or face.
