  • Title: The saliva thiocyanate analysis: a methodological extension and its relationship to CO and self-report in moderate smokers.
    Author: Abueg FR, Colletti G, Rizzo AA.
    Journal: Addict Behav; 1986; 11(1):55-8. PubMed ID: 3716917.
    Abstract:
    Parameters for the storage and analysis of saliva samples used to measure thiocyanate (SCN) levels among moderate smokers were systematically studied. The variables targeted for study were the temperature of storage (0 to 20 degrees F) and the size of the container (5 ml or 10 ml). Additionally, these same variables were examined, independently under three different temporal delays to laboratory analysis: immediate, 3 days, and 7 days. Results within each of the delay conditions revealed no significant differences in SCN levels and provided support for the reliability of measurement when using these procedures in the study of thiocyanate levels. Self-reported smoking rate and alveolar carbon monoxide (COa) readings of a week prior were found to correlate relatively highly with thiocyanate readings. These findings broaden the support for SCN as a corroborative measure of smoking.
