Lab Quality Control

Lab Quality Control is a serious business! The promise of safety and accuracy, Quality is more than a practice that can be brought with money!

How does a lab run Quality Control?

Quality is the desire of everyone who pays. This is considered value for money and also stems from existing policies and practices.

The quality control of processes and services is a serious business and admission patients and management is associated with diagnosis and treatment, which is a necessity and is an excellent addition. The procedure in the diagnostic lab has each step of approximate collection, testing the correct report for the correct patient/client and further ensuring. The following ethics and international quality practices are conscientious roads without documentary evidence, but costs require NULL and VOIDs. A quality management system (QMS) is a holy cemetery for laboratories to document and promise and demonstrate all proven quality practices for use. The proof is a quality certificate such as NABL and CAP earned by the laboratory.

Lab Quality Control (QC) facts:

  • Procedures and results aid in the validation of instrument performance as well as add reliability to patient results
  • Involves the use of certified reference material and further statistical process controls
  • The material used is similar to biological fluids tested and is made from blood, serum, urine, or spinal fluid
  • It is pre-packaged and available in a liquid or lyophilized state having a known concentration of analytes
  • These are available in different concentration ranges to include both clinically normal and abnormal ranges for every analyte tested The QC process
  • The QC materials are to be processed in the same way as patient samples
  • The good quality practice involves testing both normal and abnormal levels of QC material each day
  • Frequency of testing QC material also depends on workload for the test and hence is tested in three stages – Pre, mid, and post QC stages
  • Results from all the QC runs are evaluated to validate reporting vs. pre-defined ranges

The quality control process is not limited to running quality control materials on machines and ensuring regulatory compliance, but also uses statistics to evaluate minor or major emissions. Clinical outcomes inpatient reports can be at either end of the reporting range, so statistical bases such as mean and standard deviation applied to a consolidated quality control database help the laboratory track any irregularities.

“A practice that arises out of due diligence; QC processes lie in a roadmap which a laboratory can never decline to hold”
