* Arterial blood gas may be done if pulmonary embolism is a differential diagnosis in a patient presenting with chest pain.

* Renal function (creatinine)
* Liver function tests

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

Overview

Serial troponins and CK-MB should be ordered. Additional laboratory tests include serum electrolytes, a complete blood count, renal function tests, and liver function tests.

Laboratory Findings

On the basis of the above, a number of tests may be ordered:

Cardiac Markers

  • Troponin I or T are now cardiac marker of choice and are preferred over creatine kinase.
  • No one marker gives accurate diagnosis so commonly two markers are used for instance Troponin I or T with creatine kinase (and CK-MB fraction in many hospitals)

Blood Tests
