Instructions

The MDCH Blood Lead Analysis Report Form must be filled out and submitted with the specimen.

Specimen Collection Criteria

Collect (preferred specimen): One Royal Blue-top EDTA tube. (Min: 0.2 mL)
Also acceptable: One Lavender-top EDTA tube.

Note: Both venous and capillary blood draws are acceptable for this test.

Physician Office/Drawsite Specimen Preparation

Do not centrifuge. Maintain specimen at room temperature (20-26°C or 68-78.8°F) prior to transport. Submit MDCH Blood Lead Analysis Report Form with the specimen.

Preparation for Courier Transport

Transport: 1.0 mL whole blood at room temperature (20-26°C or 68-78.8°F). (Min: 0.2 mL)

Rejection Criteria

  • Clotted specimens.
  • Frozen specimens.
  • Specimens not collected and processed as indicated.

Storage

Specimen Stability for Testing:

Room Temperature (20-26°C or 68-78.8°F): 7 days
Refrigerated (2-8°C or 36-46°F): 1 month
Frozen (-20°C/-4°F or below): Unacceptable

Specimen Storage in Department Prior to Disposal:

Specimen retention time is determined by the policy of the reference laboratory. Contact the Sendout Laboratory with any questions.

Laboratory

Sent to Warde Medical Laboratory, Ann Arbor, MI.

Performed

Sunday - Friday.
Results available in 2-3 days. 

Reference Range

Children (0-6 Years Old)

Concentration Comment
Less than 5.0 mcg/dL Not lead-poisoned.
5.0-9.9 mcg/dL Re-screen within 6 months. Provide lead education and prevention strategies.
10.0-14.0 mcg/dL Re-screen within 3 months. Provide lead education and prevention strategies.
15.0-19.0 mcg/dL Re-screen again in 1-3 months. Provide lead education and prevention strategies.
20.0-44.0 mcg/dL Provide lead education and prevention strategies. Provide environment investigation and control current lead hazards.
45.0-69.0 mcg/dL Provide lead education and prevention strategies and refer for chelation therapy.
Greater than 70.0 mcg/dL Provide lead education and prevention strategies and hospitalize child for chelation therapy immediately. A medical emergency.
  • Elevated levels of blood lead should be confirmed with a second specimen before remedial action is instituted.
  • Elevated capillary blood specimens should be repeated using a venous specimen due to possible contamination.

 

Adults

Concentration Comment
Less than 10 ug/dL Not action required.
10.0-24.9 ug/dL Identify and minimize exposure.
25.0-49.9 ug/dL Remove from exposure if symptomatic.
50.0-79.9 ug/dL Remove from lead exposure. Immediate medical evaluation required.
Greater than or equal to 80.0 ug/dL Chelation may be indicated if symptomatic. Seek a consultation.

Test Methodology

Atomic Absorption Spectrophotometry.

Interpretation

Elevated results may be due to skin or collection-related contamination, including use of a noncertified lead-free tube. Elevated levels of blood lead should be confirmed with a second specimen collected in a lead-free tube.

Clinical Utility

This assay aids in the evaluation of lead toxicity and poisoning.

CPT Code

83655.
