Description

Specimen integrity testing is performed on all specimens that are received to ensure that optimal results are given to providers. The testing assesses specimens for absorption at 280nm (A280) and for Red Blood Cell (RBC) count. A280 testing is utilized to identify specimens that have been diluted by external agents such as saline and contrast, which can affect performance of the other tests. RBC count is performed to ensure that the specimen is not severely hemolyzed.

If a specimen fails either test, providers are alerted with a note on the results report.
