On November 21, 2005, Strategic Diagnostics Inc. (the "Company") received a Nasdaq Staff Determination letter stating that the Company is not in compliance with Nasdaq Marketplace Rule 4310(c)(14) because the Company has not timely filed its Quarterly Report on Form 10-Q for the period ended September 30, 2005, and that the Company's common stock is therefore subject to delisting from The Nasdaq National Market. As a result of the Company's filing delinquency, the letter "E" will be added to the Company's trading symbol at the opening of business on November 23, 2005. The Company has requested a hearing before a Nasdaq Listing Qualifications Panel to review the Staff Determination. The request for the hearing will stay the delisting until a decision is made by the Nasdaq Listing Qualifications Panel after the hearing.

The Company intends to file its Form 10-Q as soon as it is able to do so and will devote all necessary resources to filing as soon as possible.
