Overview
Laboratory findings consistent with the diagnosis of nasopharyngeal carcinoma include an elevated concentration of serum EBV titer.
Laboratory Findings
Laboratory findings consistent with the diagnosis of nasopharyngeal carcinoma include an elevated concentration of serum EBV titer.
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
An elevated concentration of serum EBV DNA is diagnostic of nasopharyngeal carcinoma.
- The laboratory tests which should be done for the diagnosis and assessment of tumor invasion, and differentiation of tumor are:
- Plasma EBV DNA load by PCR
- EBV viral capsid antigen
- Detection of EBV in the pathologic specimens by immunohistochically staining for latent membtane protein (LMP) or in situ hybridization for EBV-encoded RNA (EBER)
- Complete blood count (CBC)
- Urea and creatinine
- Electrolytes
- Liver function tests
- Calcium and phosphate
- Alkaline phosphatase
