Lead, Whole Blood (Maternal)
Use
Monitor maternal blood for environmental lead exposure. The Centers for Disease Control and Prevention recommends the following testing schedule for frequency of maternal blood lead follow-up during pregnancy.1 See table.
Special Instructions
The test requires a specimen collected in a royal blue-top (EDTA) tube or a tan-top lead-free tube. The sample must be submitted in its original unopened tube, and the blood should be mixed thoroughly to avoid clotting. The specimen is stable for 14 days at room temperature, refrigerated, or frozen.
Limitations
This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration (FDA). As such, it should not be considered diagnostic but rather a tool to assist in monitoring lead exposure. Its limitations include the potential for sample contamination and variations in detection sensitivity and specificity. Consultation with a clinician experienced in the management of pregnant women with elevated blood lead levels is advised for results interpretation.
