Medical Technology Licensure Examination (MTLE) Practice Exam

Using lab samples with known values is essential for ensuring the accuracy of test results by verifying control. Known value samples, often referred to as quality control samples, serve as benchmarks against which the performance of analytical procedures can be assessed. When these samples are tested, their results can be compared to the expected values. This comparison allows laboratory personnel to identify any deviations or inconsistencies that may indicate issues with the testing method, reagents, or equipment.

Incorporating samples with known values into laboratory practices helps maintain the reliability and validity of test results, which is critical for patient care and laboratory accreditation. Regular use of these control samples aids in the early detection of errors, ensuring that the data produced is accurate and trustworthy. This practice ultimately supports the overall quality assurance process within the laboratory setting.
