EXPLANATORY NOTE:

We are filing Amendment No. 1 (this “Amendment”) to the Luminex Corporation Annual Report on Form 10-K for the year ended December 31, 2006 (the “10-K”), which was originally filed on March 16, 2007, to amend Part IV, Item 15 of our 10-K for the sole purpose of amending and restating (1) the Index to Exhibits and (2) Exhibit 23.1, Consent of Independent Registered Public Accounting Firm.

This Amendment is being filed solely to correct an EDGAR conversion error. Specifically the EDGAR filing agent inadvertently omitted the current iteration of the Consent of Independent Registered Public Accounting Firm, filed as Exhibit 23.1. The correct iteration is filed herewith as Exhibit 23.1.

No other revisions or amendments have been made to Part IV, Item 15 or to any other portion of our 10-K. This Amendment does not reflect events occurring after March 16, 2007, the date of the original filing of our 10-K, or modify or update those disclosures that may have been affected by subsequent events. In addition, currently-dated certifications from our Chief Executive Officer and Chief Financial Officer have been included as exhibits to this Amendment as required by the applicable SEC rules.
