Standard and waterless protocols are available.  Pre-analytic contamination of the specimen by residual skin-surface lead is the most frequent cause of falsely-elevated (false-positive) results.  D-Lead® Soap, D-Lead® Wipe or Rinse Skin Cleaner and D-Wipe® Towels have demonstrated substantial efficacy in cleaning lead from the skin.  Use of these products for stick site cleaning and preparation may provide protection against falsely-elevated results.  These products are provided by Tamarac® Medical at no additional charge and the Tamarac® Test protocols specify their use.  Esca Tech, Inc. has, by a technology license agreement, granted to Tamarac Medical the exclusive right to use the D-Lead® Soap, D-Lead® Wipe or Rinse Skin Cleaner, and D-Wipe® Towels in conjunction with capillary blood lead or other heavy metals testing of infants, children and pregnant or lactating women in the United States.
