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

Allergen, Grass, Bent Grass/Redtop Grass : 0055057

Mnemonic: BENT GRASS

Methodology:	Quantitative ImmunoCAP® Fluorescent Enzyme Immunoassay
Performed:	Sun-Sat
Reported:	1-2 days
Specimen Required:	Patient Prep: Multiple patient encounters should be avoided. Collect: Serum separator tube. Multiple specimen tubes should be avoided. Specimen Preparation: Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.25 mL serum plus 0.1 mL for each additional allergen ordered to an ARUP Standard Transport Tube. (Min: 0.25 mL plus 0.04 mL for each allergen ordered) Storage/Transport Temperature: Refrigerated. Unacceptable Conditions: Hemolyzed, icteric, or lipemic specimens. Stability (collection to initiation of testing): After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year

Reference Interval: Less than 0.10 kU/L: No significant level detected 0.10-0.34 kU/L: Clinical relevance undetermined 0.35-0.70 kU/L: Low 0.71-3.50 kU/L: Moderate 3.51-17.50 kU/L: High 17.51 kU/L or Greater: Very High
Interpretive Data:	Allergen results of 0.10-0.34 kU/L are intended for specialist use as the clinical relevance is undetermined. Although increasing ranges are reflective of increasing concentrations of allergen-specific IgE, this may not correlate with the degree of clinical response or skin testing when challenged with a specific allergen. The correlation of allergy laboratory results with clinical history and in vivo reactivity to specific allergens is essential. A negative test may not rule out clinical allergy or even anaphylaxis.
