Quality control (QC)
Quality control implies the measures applied during each laboratory test, to verify whether the tests are working perfectly. As illustrated by Moores (2003) the main activity of quality control involves monitoring the testing process. There are several aspects of quality control, which are performed during every test. Firstly, a full set of controls should be in place, for each run of the test. Additionally, the controls, which are within every test run, should always present the results, which are within the prescribed manufacturer limits criteria. This is aimed to ensure validity and acceptability of the entire test run in the NHS laboratories. Additionally, the expiration date is continuously monitored to ensure that all the test kits are used, before their expiration date, to produce valid results. Quality control within the NHS laboratories involves closely following the physical parameters of the tests to ensure that they are for the correct performance. Some of the vital physical parameters include temperature and the incubation time (Smith & Preston, 2006).
Within every laboratory test kit, there are both positive and negative test controls, which are incorporated in every test run. These are considered the internal controls while the additional controls are considered as external controls. As illustrated by Newman (2007), the internal controls are very essential in the test run process. The external controls, on the other hand, are included in the test run so that they can monitor and ensure there is consistence in performance. Additionally, the external controls ensures that there is effective variations between various kits, as well as acting as an indicator of the of the test performance on the test samples (Szczepura, 2012).
