## Overview

[edit | edit source]

An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [disease name].

Laboratory findings consistent with the diagnosis of [disease name] include [abnormal test 1], [abnormal test 2], and [abnormal test 3].

[Test] is usually normal for patients with [disease name].

Some patients with [disease name] may have elevated/reduced concentration of [test], which is usually suggestive of [progression/complication].

There are no diagnostic laboratory findings associated with [disease name].

## Laboratory Findings

[edit | edit source]

There are no diagnostic laboratory findings associated with [disease name].

An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [disease name].

[Test] is usually normal among patients with [disease name].

Laboratory findings consistent with the diagnosis of [disease name] include:

* [Abnormal test 1]
* [Abnormal test 2]
* [Abnormal test 3]

Some patients with [disease name] may have elevated/reduced concentration of [test], which is usually suggestive of [progression/complication].

### Laboratory Diagnosis

[edit | edit source]

There are no specific laboratory findings for pineocytoma. However, the following findings are of significant

* Both serum and CSF should be assayed for alpha-fetoprotein and beta-human chorionic gonadotropin (beta-hCG) to help diagnose a germ cell tumor.
* Immunohistochemistry may be of value in detecting these markers or placental alkaline phosphatase.
