Definition
laboratories are efficient and working at the highest standards
Term
How can labs pass inspection?
Definition
following proper procedure at all times, and maintains proper documentation
Term
if a laboratory has a deficiency what has to be done?
Definition
deficiency has to be corrected on site or by documentation to CAP before accreditation
Term
4 inspector instructions
Definition

specimen prep area (clean)
specimen processing area with specialized fume hood (dirty)
specimen testing area (clean)
Term
What are wipe tests and why are they done?
Definition
swab instruments monthly to confirm absence of contamination, performed when contamination is suspected
Term
Why do documents regarding set-up and normal operations need to be available?
Definition
routine maintenance, and instrument troubleshooting
Term
What proficiency testing procedures?
Definition
labs send multiple specimens to groups of labs for comparison analysis, PTs are integrated into the daily workload
Term
If PT is not required what is done instead?
Definition
participation in external PT or by utilizing an alternative method for determining the reliability of the results
Term
define quality assurance
Definition
every action in the lab must be documented in the procedure manual to assure quality across the lab
Term
define quality control
Definition
techniques for monitoring performance
Term
What are the components of the procedure manual?
Definition
written QM/QC program in place, shows how to run the lab start to finish, and shows how to handle problems that are encountered
Term
assay validation
Definition
documented to verify performance of the molecular test
Term
Diagnostic and analytical sensitivity
Definition
diagnostic = ability to detect a disease or condition
analytical = ability of an assay to detect a given analyte
Term
diagnostic and analytical specificity
Definition
diagnostic= degree to which an assay is negative when disease is absent
analytical = degree to which interfering substances are not detected in an assay
