CLIA is Clinical Laboratory Improvement Amendments of 1988.

NOTES: New York state and Washington state are exempt from CLIA because they have their own regulatory requirements. Waived laboratories perform only tests that have been classified as waived, which are generally simple with low risk of erroneous results.
