                                ----------------

I, Steven M. Peltzman, certify that:

          1. I have reviewed this quarterly report on Form 10-QSB of Saliva
          Diagnostic Systems, Inc.; 2. Based on my knowledge, this report does
          not contain any untrue statement of a material fact or omit to state
              a material fact necessary to make the statements made, in light of
              the circumstances under which such statements were made, not
              misleading with respect to the period covered by this report;
          3.  Based on my knowledge, the financial statements, and other
              financial information included in this report, fairly present in
              all material respects the financial condition, results of
              operations and cash flows of the registrant as of, and for, the
              periods presented in this report;
          4.  I am responsible for establishing and maintaining disclosure
              controls and procedures [as defined in Exchange Act Rules
              13a-15(e) and 15d-15(e)] for the registrant and have: (a) Designed
              such disclosure controls and procedures, or caused such disclosure
              controls and procedures to
                     be designed under our supervision, to ensure that material
                     information relating to the registrant, including its
                     consolidated subsidiaries, is made known to us by others
                     within those entities, particularly during the period in
                     which this report is being prepared;
              (b)    Evaluated the effectiveness of the registrant's disclosure
                     controls and procedures and presented in this report our
                     conclusions about the effectiveness of the disclosure
                     controls and procedures, as of the end of the period
                     covered by this report based on such evaluation; and
              (c)    Disclosed in this report any change in the registrant's
                     internal control over financial reporting that occurred
                     during the registrant's most recent fiscal quarter (the
                     registrant's fourth fiscal quarter in the case of an annual
                     report) that has materially affected, or is reasonably
                     likely to materially affect, the registrant's internal
                     control over financial reporting; and
          5.  I have disclosed, based on my most recent evaluation of internal
              control over financial reporting, to the registrant's auditors and
              the audit committee of the registrant's board of directors (or
              persons performing the equivalent functions):
              (a)    All significant deficiencies and material weaknesses in the
                     design or operation of internal control over financial
                     reporting which are reasonably likely to adversely affect
                     the registrant's ability to record, process, summarize and
                     report financial information; and
              (b)    Any fraud, whether or not material, that involves
                     management or other employees who have a significant role
                     in the registrant's internal control over financial
                     reporting.
