Specimen Requirements | |||||
Specimen Type: | Whole blood (capillary or venous). Venous samples are acceptable for screening and are required for follow-up samples on patients found to have elevated capillary lead levels. NOTE: Specimens are easily contaminated with lead, so certain precautions are required during the collection process for a valid result. The clinic area, and the collector’s clothes and gloves, must be as clean and dust free as possible. | ||||
Patient Preparation: | For capillary samples, wash child’s hand with warm water and soap. Gentle scrubbing will stimulate circulation to the fingers. Wrap hand in paper towel to prevent recontamination. Keep wrapped until you are ready for the finger stick. | ||||
Collection Instructions: |
Capillary Collection (Finger stick): CB-300, Microvette, or similar tubes are acceptable for screening only. A venous specimen must be submitted for confirmation of elevated levels. With each batch of samples submitted, one unused sampling container MUST be submitted as a quality control check for contamination.
