Exhibit 31.2
                                  CERTIFICATION

I, Robert F. McCullough, Jr., 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.
