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

Patient History For Cytogenetic (Chromosome) Studies

Mnemonic: CHR PB

Methodology:	Giemsa Band
Performed:	Sun-Sat
Reported:	3-10 days
Specimen Required:	Collect: Green (sodium heparin). Specimen Preparation: Do not freeze or expose to extreme temperatures. Transport 10 mL whole blood. (Min: 2 mL) Specimen and completed test request form, including clinical indication, must be received within 48 hours of collection. Storage/Transport Temperature: Room temperature. Remarks: This test must be ordered using Cytogenetic test request form #43097 or through your ARUP interface.

After specimen receipt, results are generally available in an average of 10 days. A processing fee will be charged if this procedure is canceled, at the client's request, after the test has been set up, or if the specimen integrity is inadequate to allow culture growth.
