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
- Measuring the levels of thyroid hormones (T4) and thyroid releasing hormone (TSH) is performed to confirm the diagnosis of cretinism.[1]
- Laboratory findings consistent with cretinism differ according to the underlying cause. Laboratory findings according to the causes are as the following:
- Primary congenital hypothyroidism: High TSH and low T4 levels.
- Subclinical hypothyroidism: High TSH and normal T4 levels.
- Secondary (central) hypothyroidism: Low TSH and low T4 levels.
