Don’t proceed with testing or reporting when sample quality or identification is suspect.

The quality of specimens received in the laboratory is paramount to obtaining accurate results. Proceeding with testing in the presence of poor sample quality may give misleading results. This contributes to delays and unnecessary repeat examinations. Any level of error should be avoided to decrease negative impact on clinical decisions and patient care. Laboratory professionals should be proactive in ensuring that all types of specimens are collected in a high quality manner with correct identification, regardless of which health professional group is performing the act.
