RE:  ADEZA BIOMEDICAL CORPORATION
     AMENDMENT NO. 2 TO REGISTRATION STATEMENT ON FORM S-1,
     FILED OCTOBER 27, 2004 (FILE NO. 333-118012)

Dear Mr. Peklenk:

     On behalf of Adeza Biomedical Corporation ("Adeza"), this letter responds
to the comments of the Staff of the Securities and Exchange Commission (the
"Staff") set forth in the letter dated November 16, 2004 in connection with the
filing of the above-referenced registration statement (the "Registration
Statement"). As has been agreed with the Staff, the revisions that Adeza
proposes to make to the Registration Statement in response to the Staff's
comments are explained in the body of this letter. Adeza intends to file an
amendment to the Registration Statement after the Staff has reviewed Adeza's
proposed revisions to the Registration Statement.

     In accordance with 17 C.F.R. ss. 200.83(c), we have provided a letter to
the Staff and the Office of Freedom of Information and Privacy Act Operations
requesting confidential treatment for certain portions of Adeza's responses set
forth in this response letter (the "Specified Information"). Adeza has redacted
the Specified Information from the letter filed via EDGAR and has included such
information solely in paper copies of the letter submitted to the Staff.

     The responses below correspond to the paragraph numbers of the Staff's
letter. The pages referenced below correspond to the page numbers in the
Registration Statement.

Cost of product sales, page 33

2. In response to the Staff's comment, Adeza proposes to make the following
revisions to the Registration Statement:

     a. The disclosure on page 33 of the Registration Statement under "Overview
- - Cost of Product Sales" would be revised to read in its entirety as follows:

     "COST OF PRODUCT SALES

     Our cost of product sales represents the cost of materials, overhead
     associated with the manufacture of our products, direct labor, delivery
     charges, lab services, royalties and product warranty obligations.

     [*]"

     b. The disclosure on pages 35-36 of the Registration Statement under
"RESULTS OF OPERATIONS - Nine months ended September 30, 2004 as compared to the
nine months ended September 30, 2003 - Cost of product sales" would be revised
in its entirety to read as follows:

     "COST OF PRODUCT SALES

     Cost of product sales for the nine months ended September 30, 2004 was $0.9
     million, a decrease of $3.7 million from $4.6 million for the nine months
     ended September 30, 2003. The decrease in cost of product sales was
     primarily the result of reduced royalty costs of $1.0 million and a
     one-time reduction in accrued royalties of $2.7 million that we determined
     were in excess of amounts actually due. [*] In addition, decrease in other
     product costs of $0.6 million was offset by $0.6 million of costs related
     to increased unit volumes for the nine months ended September 2004 as
     compared to the nine months ended September 2003. Non-royalty related costs
     were unchanged for the period ended September 30, 2004 from the period
     ended September 30, 2003 as costs related to increased unit sales were
     offset by lower unit manufacturing costs. As a percent of revenue, cost of
     sales was 14.9% of revenue for the nine months ended September 30, 2004,
     excluding the effect of the one-time reduction in accrued

     to the reduction in royalty costs."

     Adeza has entered into license, clinical trial, supply, and sponsored
     research and development agreements with universities, research
     organizations, and commercial companies. Certain of these agreements
     require payments of royalties on future sales of products resulting from
     such agreements and may subject Adeza to minimum annual royalty payments to
     such contract partners. [*]"
