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

Lead, Industrial Exposure Panel, Adults : 0025016

Mnemonic: LEAD-IND

Methodology:	Inductively Coupled Plasma/Mass Spectrometry/Hematofluorometry
Performed:	Mon-Fri
Reported:	1-5 days
Specimen Required:	Collect: One 7 mL royal blue (K₂EDTA) or (Na₂EDTA) or 3 mL tan (K₂EDTA). Heparin anticoagulant is not acceptable. Transport: 7 mL whole blood (royal blue, K₂EDTA or Na₂EDTA) or 3 mL whole blood (tan, K₂EDTA) at 2-8°C. (Min: 2 mL) Pediatric Collection/Transport: Not available for children under age 16. Remarks: Protect from light during collection, storage, and shipment. Unacceptable Conditions: Frozen, hemolyzed, or clotted samples, and heparin anticoagulant. Stability: Ambient: 30 hours; Refrigerated: 5 weeks; Frozen: Unacceptable

Reference Interval:

Test Number	Components	Reference Interval
	Lead, Blood	0-15 years: 0.0-9.9 µg/dL 16 years and older: 0.0-24.9 µg/dL
	Zinc Protoporphyrin (ZPP), Whole Blood	0-40 µg/dL
	Zinc Protoporphyrin (ZPP) to Heme Ratio	0-69 µmol ZPP/mol heme

Interpretive Data:

Action required for workers with Elevated Lead Values OSHA, Occupational Exposure to Lead, 1978
No. of Tests	Lead	Action Required
1	³ 40.0 µg/dL	Notification of workers in writing; medical examination of worker and consultation.
3	³ 50.0 µg/dL	Removal of worker from job with potential lead exposure.
1	³ 60.0 µg/dL	Removal of worker from job with potential lead exposure.
2	£ 40.0 µg/dL	Reinstatement of worker in job with potential lead exposure is based upon symptoms and medical evaluation.
OSHA requirements in effect since 1978 call for the measurement of whole blood lead and zinc protoporphyrins (ZPP) (NCCLS document C42-A, Nov. 1996) to evaluate the occupational exposure to lead. OSHA requires ZPP whole blood testing to be reported in units of µg/dL. Federal lead construction standards require a worker to be notified and removed from the job at levels of 50 µg/dL and higher, until physician authorizes return.

CPT Code(s):

83655 Lead; 84202 Zinc Protoporphyrin
