	*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

Mercury, Whole Blood : 0099305

Mnemonic: HG B

Methodology:	Quantitative Atomic Absorption/Quantitative Inductively Coupled Plasma-Mass Spectrometry
Performed:	Sun-Sat
Reported:	1-2 days
Specimen Required:	Patient Prep: Diet, medication, and nutritional supplements may introduce interfering substances. Patient should be encouraged to discontinue nutritional supplements, vitamins, minerals, and non-essential over-the-counter medications (upon the advice of their physician), and avoid shellfish and seafood for 48 to 72 hours. Collect: Royal blue (K₂EDTA or Na₂EDTA). Specimen Preparation: Transport 7 mL whole blood in the original collection tube. (Min: 0.5 mL) Storage/Transport Temperature: Room temperature. Also acceptable: Refrigerated. Unacceptable Conditions: Heparin anticoagulant. Frozen specimens. Stability (collection to initiation of testing): Mercury is volatile; concentration may reduce after seven or more days of storage.

Reference Interval: 0-10 µg/L
Interpretive Data:	This test measures total mercury, whereas the reference interval relates to inorganic mercury concentrations. Dietary and non-occupational exposure to organic mercury species may contribute to an elevated total mercury result.
Note:	Elevated results from noncertified trace element-free collection tubes may be due to contamination. Elevated concentrations of trace elements in blood should be confirmed with a second specimen collected in a tube designed for trace element determinations, such as a royal blue (Na₂EDTA) tube.
CPT Code(s):	83825
Cross References:	Hg (Mercury, Whole Blood), HGB (Mercury, Whole Blood)
