CLIA regulations categorize laboratory tests into three complexity levels:
Waived Tests: These are simple tests with a low risk of error, such as some rapid diagnostic tests. Moderate Complexity Tests: These require more technical expertise and are subject to more stringent quality control measures. High Complexity Tests: These involve complex testing procedures and require the highest level of oversight and proficiency testing.
Histology laboratories typically fall under the high complexity category due to the specialized nature of the tests performed.
