<body>
<p>This final rule responds to comments received on the proposal to update proficiency testing (PT) regulations under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) to address current analytes (that is, substances or constituents for which the laboratory conducts testing) and newer technologies. This rule may also make additional technical changes to PT referral regulations to more closely align them with the CLIA statute.</p>
