Search Tips

Wildcards Symbol (*)

The wildcard symbol (*) can be used in place of letters or characters in query words to search for different permutations of a word.

*	Can be in any position in the term and matches any number of characters.
Examples:	hemo*	matches hemolytic, hemophilia and hemophilia
	*NA	matches DNA and RNA
	*tet**	matches text and test
	BCL*	matches bcl-1/JH and bcl-2/JH
	virus*	matches virus or viruses
	*glucan*	matches beta-1,3-d-Glucan

Boolean Parameters

Search terms can be a single word or several words. The search engine automatically inserts and between words if nothing else is specified, so the Boolean term and can be omitted in search terms. For example, searching for tissue assay is the same as searching for tissue AND assay.

Quotes can be used to search for phrases. For example:

"tissue assay "

Words must be present in the specified order with no intervening words

The following boolean connectors can be used: AND, OR, NOT Examples:

tissue AND assay	Both words must be present
tissue OR assay	Either word can be present
assay NOT tissue	Only assay can be present, tissue cannot appear on the page

Epstein-Barr Virus Antibody to Viral Capsid Antigen, IgM : 0050240

Mnemonic: EBV M

Methodology:	Semi-Quantitative Chemiluminescent Immunoassay
Performed:	Mon-Sun
Reported:	1-2 days
Specimen Required:	Collect: Serum separator tube. Specimen Preparation: Separate serum from cells ASAP or within 2 hours of collection. Transfer 2 mL serum to an ARUP Standard Transport Tube. (Min: 0.5 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as "acute" or "convalescent." Storage/Transport Temperature: Refrigerated. Unacceptable Conditions: Tissue or urine. Contaminated or heat-inactivated specimens. Stability (collection to initiation of testing): After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Reference Interval: 35.9 U/mL or less: Negative - No significant level of detectable IgM antibody to EBV viral capsid antigen. 36.0-43.9 U/mL: Equivocal - Repeat testing in 10-14 days may be helpful. 44.0 U/mL or greater: Positive - IgM antibody to EBV viral capsid antigen detected, which may indicate a current or recent EBV infection.
Interpretive Data:	Interpretive information regarding serologic features of EBV-associated diseases is available at www.arupconsult.com/ebvdx.
Note:	EBV IgM values obtained with different manufacturers' assay methods may not be used interchangeably. The magnitude of the reported EBV IgM level cannot be correlated to an endpoint titer.
CPT Code(s):	86665
