Exhibit 31.2

                                  CERTIFICATION

I, Robert McCullough, certify that:

      (1) I have  reviewed  this  quarterly  report on Form 10-QSB of  Molecular
      Diagnostics, 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 small  business  issuer as of, and for, the periods  presented in this
      report;

      (4)  The  small  business  issuer's  other  certifying  officer  and I are
      responsible  for  establishing  and  maintaining  disclosure  controls and
      procedures (as defined in Exchange Act Rules  13a-15(e) and 15d-15(e)) for
      the small business issuer 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  small  business  issuer,  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 small  business  issuer'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 small  business
                  issuer's  internal  control  over  financial   reporting  that
                  occurred during the small business issuer's most recent fiscal
                  quarter (the small business  issuer's fourth fiscal quarter in
                  the case of an annual report) that has materially affected, or
                  is reasonably likely to materially  affect, the small business
                  issuer's internal control over financial reporting; and

      (5) The  small  business  issuer's  other  certifying  officer  and I have
      disclosed,  based on our most recent  evaluation of internal  control over
      financial reporting, to the small business issuer's auditors and the audit
      committee of the small  business  issuer'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
                  small business issuer'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 small
                  business issuer's internal control over financial reporting.
