Question

The most appropriate way for a small, in-house laboratory to check the accuracy of its blood chemistry analyses is to periodically:

A. Allow all laboratory staff to run the test and average their results.
B. Analyze control samples with in-house equipment to check accuracy.
C. Run multiple samples of unknown values and average the results.
D. Obtain dry reagent strips, run the test using a strip, run the test using the chemistry instrument, and compare the results.

Answer 1

The most appropriate way for a small, in-house laboratory to check the accuracy of its blood chemistry analyses is to periodically analyze control samples with in-house equipment to check accuracy.

Step-by-step explanation:

The most appropriate way for a small, in-house laboratory to check the accuracy of its blood chemistry analyses is to periodically analyze control samples with in-house equipment to check accuracy.

Control samples are samples with known values that are used to validate the accuracy and reliability of laboratory tests. By analyzing control samples, the laboratory can compare the results obtained from their equipment with the known values, ensuring that the equipment is functioning correctly and producing accurate results.

This method is preferred over the other options because it directly assesses the accuracy of the laboratory's equipment and procedures in measuring known values, providing a reliable measure of the laboratory's performance.
