AGENCY:

ACTION:

Notice.

SUMMARY:

The Food and Drug Administration (FDA) is announcing the availability of a document entitled “Guidance for Industry: `Computer Crossmatch' (Computerized Analysis of the Compatibility between the Donor's Cell Type and the Recipient's Serum or Plasma Type)” dated April 2011. The guidance document provides blood establishments that perform compatibility testing using a computer crossmatch system to perform computerized matching of blood with recommendations consistent with current good manufacturing practice (CGMP) requirements. Blood establishments are required to have standard operating procedures to demonstrate incompatibility between the donor's cell type and the recipient's serum or plasma type. The guidance describes practices that we believe satisfy those requirements to help ensure detection of an incompatible crossmatch when using a computerized system for matching a donor's cell type with a recipient's serum or plasma type. The guidance announced in this notice finalizes the draft guidance entitled “Guidance for Industry: `Computer Crossmatch' (Electronic Based Testing for the Compatibility between the Donor's Cell Type and the Recipient's Serum or Plasma Type)” dated June 2007.

DATES:

Submit either electronic or written comments on Agency guidances at any time.

ADDRESSES:

I. Background

FDA is announcing the availability of a document entitled “Guidance for Industry: ‘Computer Crossmatch’ (Computerized Analysis of the Compatibility between the Donor's Cell Type and the Recipient's Serum or Plasma Type)” dated April 2011. The guidance document provides blood establishments that perform compatibility testing using a computer crossmatch system to perform computerized matching of blood with recommendations consistent with Start Printed Page 23825CGMP requirements in 21 CFR Parts 210, 211, and 606.

In the Federal Register of August 6, 2001 (66 FR 40886), FDA issued a final rule that revised 21 CFR 606.151(c) to allow for the use of either a serologic crossmatch or a computer crossmatch as an acceptable method of establishing the compatibility between the donor's cell type and recipient's serum or plasma type (i.e., major crossmatch). Prior to the issuance of the final rule, a blood establishment could only use a computer crossmatch if FDA gave its written approval for the use of a computer crossmatch as an alternative procedure under 21 CFR 640.120. With this revision to 21 CFR 606.151(c), establishments are no longer required to submit an application to FDA to permit use of a computer crossmatch as an alterative procedure. The guidance does not apply to those circumstances where the donor's blood has not been screened for agglutinating, coating and hemolytic antibodies. In such cases, 21 CFR 606.151(d) requires that “* * * the recipient's cells shall be tested with the donor's serum (minor crossmatch) by a method that will so demonstrate.”

The guidance document describes the practices that FDA believes satisfy the requirements in 21 CFR 606.151(c) to help ensure detection of an incompatible crossmatch when using a computerized system for matching a donor's cell type with a recipient's serum or plasma type. We consider computer crossmatch an acceptable method of compatibility analysis when it is properly designed, validated, implemented, and monitored. In addition, the guidance contains recommendations for blood establishments performing compatibility testing that intend to implement a computer crossmatch procedure. For licensed establishments, the guidance also describes how to report this manufacturing change to FDA under 21 CFR 601.12.

In the Federal Register of June 21, 2007 (72 FR 34259), FDA announced the availability of the draft guidance entitled “Guidance for Industry: `Computer Crossmatch' (Electronic Based Testing for the Compatibility between the Donor's Cell Type and the Recipient's Serum or Plasma Type)” dated June 2007. FDA received several comments on the draft guidance and those comments were considered as the guidance was finalized. In addition, editorial changes were made to improve clarity. The guidance announced in this notice finalizes the draft guidance dated June 2007.

The guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents FDA's current thinking on this topic. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statutes and regulations.

II. Paperwork Reduction Act of 1995

The guidance refers to previously approved collections of information found in FDA regulations. These collections of information are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The collections of information in 21 CFR 211.68(a) and (b) and 211.100(a) have been approved under OMB control number 0910-0139. The collections of information in 21 CFR 606.100(b), 606.121, 606.151, and 606.160 have been approved under OMB control number 0910-0116. The collections of information in 21 CFR 601.12 have been approved under OMB control number 0910-0338.

III. Comments

Interested persons may submit to the Division of Dockets Management (see ADDRESSES) either electronic or written comments regarding this document. It is only necessary to send one set of comments. It is no longer necessary to send two copies of mailed comments. Identify comments with the docket number found in brackets in the heading of this document. Received comments may be seen in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday through Friday.
