Overview
An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [disease name].
OR
Laboratory findings consistent with the diagnosis of [disease name] include [abnormal test 1], [abnormal test 2], and [abnormal test 3].
OR
[Test] is usually normal among patients with [disease name].
OR
Some patients with [disease name] may have elevated/reduced concentration of [test], which is usually suggestive of [progression/complication].
OR
There are no diagnostic laboratory findings associated with [disease name].
Laboratory Findings
- There are no diagnostic laboratory findings associated with cerebral palsy
- The American Academy of Neurology (AAN) recommends lab studies
- If there is no specific structural abnormality present-
- Presence of atypical features in history or physical examination
- Cerebral palsy associated with brain malformation
- Following labs may help to rule out other diseases
- Thyroid function tests- to rule out muscle or movement disorders
- Lactate and pyruvate levels- may show mitochondrial abnormalities
- Organic and amino acids- serum and urine levels may be deranged in inherited metabolic disorders
- Ammonia levels- elevated in liver dysfunction or urea cycle defect
- Chromosomal analysis
- Karyotype analysis
- Specific DNA testing
- Elevated CSF protein levels
- Diagnostic testing for coagulation disorders, if cerebral infarction is suspected
