If your laboratory has already conducted a blind study for these analyses in 2000, please supply this office with a
copy of the results. If a blind study was not completed in 2000, your laboratory must secure and analyze
performance evaluation samples and have your approved selected vendor provide us with the results. Likewise, our
program requires that you arrange to procure blind follow-up samples for all unacceptable results. Please notify this
office within 10 days, by fax, e-mail, telephone, or U.S. Postal service of your intent to complete these requirements.
