         Re:  Review of Avitar, Inc. Form 10-KSB for the Fiscal Year Ended
                 September 30, 2004 (SEC File No. 1-15695)

Dear Mr. Todd:

The following is our response to your letter dated February 4, 2005 containing
comments on the review of our Form 10-KSB for the fiscal year ended September
30, 2004 (references are to numbered paragraphs in your letter). The amended
Form 10-KSB including amended Consolidated Financial Statements referred to in
our responses have been filed.

Form 10-KSB for the Fiscal Year Ended September 30, 2004

Item 6.  Management's Discussion and Analysis or Plan of Operation

             Results of Operations

1    Form 10-KSB has been amended to include  factors  responsible for decreased
     sales of foam products.

2    Form 10-KSB has been amended to quantify the various  items that  benefited
     gross margin.

3.   Form  10-KSB has been  amended to explain  the reason for the  expense  for
     product replacements and why a significant amount of inventory expired.

4.   The Company has no obligation to replace expired  inventory  including that
     held by its customers.

5.   The MD&A in the Form 10-KSB has been amended to describe the cost reduction
     program that was implemented by management due to capital  constraints that
     the Company  experienced  during Fiscal 2003.  Since these cost  reductions
     were not  attributable to a restructuring  of the business,  no disclosures
     are required under SAB Topic 5-P.


6.   No disclosures  are required  pursuant to FAS 146 since the cost reductions
     were not related to exit or disposal activities.

7.   Form 10-KSB has been amended to identify, and describe the reasons for, the
     increases  in the expense  items that  resulted in an offset to the expense
     control initiatives.

8.   Form 10-KSB has been amended to explain that sales and  marketing  expenses
     increases  were a  result  of  additional  sales  and  marketing  resources
     employed during the latter part of Fiscal 2004.

9.   Form  10-KSB  has been  amended to more  fully  describe  the basis for the
     reduction in accrued royalties. In 1999, the Company entered into a product
     development agreement with a supplier to develop certain components of oral
     fluid drugs of abuse tests (a three panel test and a five panel test) Under
     the terms of this agreement:

o    The  supplier  would  develop  these  components  in  accordance  with  the
     Development Program specifications set forth in the agreement;

o    The  Company  was  entitled  to all  proprietary  rights  to  all  products
     developed under the agreement; o The supplier was to manufacture and supply
     components  of the drug tests to the Company for the price  established  in
     the agreement;

o    The  Company  paid  the  supplier  monthly  fees  as  compensation  for the
     Development Program;

o    Upon  completion  of the  Development  Program,  the Company  would pay the
     supplier  royalty  payments  based  on the  Company's  gross  sales  of the
     products developed under the agreement.

     During the period  from 1999 to 2002,  the Company did sell drug tests that
     included  components  of the drug  tests  developed  and  furnished  by the
     supplier.  Based on the sales of these drug tests and the expectation  that
     the  supplier  would  complete  its  obligations  in  connection  with  the
     Development Program, the Company accrued royalties due to the supplier upon
     completion of the Development  Program.  In 2002, the Company  notified the
     supplier  that the  supplier  failed to perform its  obligations  under the
     agreement as specified in the Development Program for which it had received
     substantial  payments.  Since that time,  the  supplier has done nothing to
     cure this  default.  In view of this lapse in time and that  other  product
     undertakings  by the supplier  would  prevent the supplier from ever curing
     any of its defaults  under the  agreement,  there was no longer any need to
     maintain the royalty reserve for this supplier.



            Financial Condition and Liquidity

10.  Form  10-KSB  has been  amended  to provide a more  complete  analysis  and
     explanation of the sources and uses of operating resources.

11.  Form  10-KSB has been  amended to explain the change in the  components  of
     working capital as they impact cash flows from operations.

12.  Form  10-KSB has been  amended to  describe  why there was an  increase  in
     accounts receivables in light of the decrease in sales for Fiscal 2004.

13.  Form 10-KSB has been amended to provide more disclosure about the Company's
     listing  standards  compliance plan with AMEX. With respect to implications
     for  investors  if the Company  were  delisted  from the AMEX,  it would be
     difficult  for the Company to determine  or predict for its 9,000+  current
     shareholders or potential  investors the  implications of such an action by
     AMEX.  Based on the disclosure  that delisting  could result if the Company
     does not comply with the plan, shareholders or potential investors would be
     in the best  position  to assess  how  delisting  would  impact  upon their
     investment or potential investment.

           Critical Accounting Policies

14.  Form  10-KSB  has  been  amended  to  provide  expanded  disclosure  on the
     Company's revenue recognition policy.

           Item 8A.  Controls and Procedures

15.  Form 10-KSB has been amended to include that the officers' conclusions that
     controls and procedures in place are effective as well as adequate.

Consolidated Financial Statements

Note 2.  Summary of Significant Accounting Policies

           Inventories

16.  Consolidated Financial Statements have been amended to describe the process
     used to assess inventory for potential impairment.


            Long-lived Assets

17.  Consolidated  Financial  Statements  have  been  amended  to  describe  the
     policies and practices for applying FAS 144.

Note 6.  Goodwill

18.  Consolidated   Financial   Statements  have  been  amended  to  state  that
     management was responsible for the valuation of goodwill.

     In connection  with our response to your comments,  it is understood by the
Company that:

o    The Company is responsible  for the adequacy and accuracy of the disclosure
     in the filings;

o    SEC staff  comments  or  changes to  disclosure  in  response  to SEC staff
     comments  in the  filings  reviewed  by the  staff  do  not  foreclose  the
     Commission from taking any action with respect to the filing; and

o    The Company may not assert  staff  comments as a defense in any  proceeding
     initiated by the Commission or any person under the federal securities laws
     of the United States.
