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

Porphyrins Profile, Plasma INACTIVATED 5/15/2012. Refer to Porphyrins, Total with Reflex to Fractionation and Quantitation, Plasma (2006593) : 0092012

Mnemonic: PORPH PRO

Methodology:	High Performance Liquid Chromatography/Extraction/Scanning Spectrofluorometry (High Performance Liquid Chromatography/Fluorometry)
Performed:	Varies
Reported:	3-8 days
Specimen Required:	Patient Prep: Patient should abstain from alcohol for 24 hours prior to test. Collect: Green (sodium heparin). Also acceptable: lavender (EDTA). Specimen Preparation: Protect from light. Transfer 3 mL plasma to an ARUP Amber Transport Tube and freeze immediately. (Min: 1 mL) Storage/Transport Temperature: CRITICAL FROZEN. Separate specimens must be submitted when multiple tests are ordered. Remarks: Include a current list of medications. Unacceptable Conditions: Separator tubes. Specimens not protected from light. Specimens that have been thawed. Stability (collection to initiation of testing): Ambient: Unacceptable; Refrigerated: Unacceptable; Frozen: 1 week

Reference Interval: By report
Note:	This profile begins with the extraction and quantitation of total porphyrins in plasma. If the result for the total is greater than 1.0 fractionation will be performed at an additional charge.
CPT Code(s):	84311 Porphyrins total; 82492 add if fractionation is performed
