The recovery of human saliva using the Salivette system

Human saliva recovery using the Salivette system was investigated. Two Salivette systems were employed. The recommended centrifugation procedures for saliva recovery only recovered between 46% and 52% of the total volume. Modification of centrifugation speeds and duration allowed an 80% recovery. Differences were observed between the two Salivette systems tested with the newer system allowing a greater recovery. The findings have implications for saliva collection using this technique.
