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 for 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
- Complete blood count is usullay done to rull out anemia as a cause of dyspnea.
- Tyroid tests are usually done because tyroid disease is usullay associated with bilateral diaphragamtic paralysis.
- Laboratory test is usually normal among patients with unilateral daiphragmatic paralysis.
- Laboratory findings consistent with the diagnosis of diaphragmatic paralysis include:[1]
- Reduced oxygen saturation in the supine position in unilateral and bilateral diphragmatic paralysis
- Elevated arterial partial pressure of carbon dioxide (PaCO2) in bilateral diaphragmatic paralysis
- Hpoxemia may be seen in arterial blood gas in bilateral diaphragmatic paralysis.
- Based on the causes of diaphragmatic paralysis, more laboratory tests may be needed.
