IQCP: Where Are We Now?

What is IQCP?

IQCP stands for Individualized Quality Control Plan, and it is an all-inclusive approach to creating a customized quality control plan for a laboratory.

IQCP focuses on assuring quality in the lab using more in-depth means than simply carrying out a certain number of QC tests at a specific frequency. Many different aspects of laboratory operations will be evaluated, such as the test system, reagents, environment, testing personnel etc.

Where are we now?

As of January 2016, many labs in and outside the USA have implemented their IQCP’s, but what impact has this had on day-to-day operations?

In order to gauge the overall effectiveness and user-experience of implementing IQCP, Westgard QC1 conducted a survey for all IQCP participants both in the USA and globally.

Opinions were mixed regarding the effectiveness of IQCP:

Positive Opinions of IQCP

  • Some users found that IQCP decreased the number of QC materials required
  • There is a greater emphasis on the pre and post-analytic phases of testing, thus improving process error identification
  • Over half of global survey participants revealed that their IQCP identified unacceptable risk(s) in their test system, thereby creating a more robust process
  • Of the labs whose IQCP’s were inspected in the USA, 96.3% were deemed adequate by the relevant regulatory bodyies
  • Identification of errors can lead to additional personnel training, thereby increasing the knowledge and expertise of laboratory staff

Negative Opinions of IQCP

  • Due to the length of time taken to create a single IQCP, coupled with the additional expense, several survey participants found that the benefits of IQCP did not justify using so many resources in its implementation
  • Many labs raised concerns regarding the availability of guidance in developing an IQCP. Participants complained that useful guidelines were not provided quickly enough, and labs had to rush their IQCP implementation.
  • Several survey participants felt as though there was widespread confusion over IQCP. Participants highlighted that the volume of questions from laboratory professionals proves that IQCP was not introduced by regulatory bodies in an organized or effective manner
  • Some labs surveyed voiced the opinion that IQCP evaluation needs to be more standardized, and that inspections can either be too lenient or too stringent.

ISO 15189:2012 requirements

As with any new system, feedback is important for further refinement. IQCP appears to be a step in the right direction for the advancement of laboratory QC. According to Westgard’s survey1, only around 30% of US respondents were satisfied, showing that labs still feel improvements need to be made. Inspectoral standardization, or more concise, straightforward guidelines on IQCP implementation could be potential improvements for regulatory bodies to consider.

We would love to know your thoughts on the subject. Send us an email at acusera@randox.com.

Does Your QC Cover Clinically Relevant Ranges?

Following recommendations from recognized institutions such as ISO and CLIA, more laboratories are using third party controls than ever before. However, great care should be taken when choosing which third party control to use. A number of factors should be considered, and primarily among these is whether the control challenges the complete Clinical Range and the Medical Decision Levels. ISO 15189:2012 states that ‘The laboratory should choose concentrations of control materials wherever possible, especially at or near clinical decision values, which ensure the validity of decisions made’.

Measuring the Complete Clinical Range

It is important to assess the full clinical range of an assay i.e. the range between the lowest and highest results which can be reliably reported. In order to make sure a laboratory instrument is working across the full clinical range, a QC which covers low, normal and elevated concentrations must be used.

Question: “If the full clinical range isn’t covered by QC, how will we know whether patient results which fall outside the range of quality controls are accurately reported?”

What are Medical Decision Levels?

Medical Decision Levels (MDL) are the analyte values at which medical professionals can determine whether a patient may be suffering from a certain condition. The MDL is determined by a consensus of medical professionals and clinical research. Patients’ test results are compared to the MDL and appropriate diagnoses or medical interventions can be made.

For example, the MDL of Glucose can indicate a certain diabetic status:

Analyte Medical Decision Level Diagnostic Status
Glucose (fasting) <100 mg/dL Non-Diabetic
100–125 mg/dL Pre-Diabetic
>125 mg/dL Diabetic

Competitor QC

Many QC manufacturers ‘cut corners’ in an attempt to keep costs down, which often results in the sale of controls which do not cover the complete clinical range or vital medical decision levels. Below is an example of the Glucose concentrations present in a competitor control:

Competitor Chemistry Control Level 1 – 68 mg/dL

Competitor Chemistry Control Level 2 – 134 mg/dL

Competitor Chemistry Control Level 3 – 386 mg/dL

In the examples above, the competitor’s level 1 control covers the non-diabetic MDL, but the level 2 control is not within the ‘Pre-Diabetic’ decision range. The level 3 control is also much higher than can be expected for an elevated diabetic patient result (200 mg/dL or more).

Randox QC

Due to the superior manufacturing process used by Randox, QC target values are consistently within the MDL of tests. For example, the Glucose concentrations present in our Liquid Assayed Chemistry Premium Plus control are:

Level 1 – 57 mg/dL

Level 2 – 114 mg/dL

Level 3 – 236 mg/dL

The MDL for Glucose is covered by the Randox control, meaning laboratory professionals can be confident that patient results will be accurately interpreted.

Immunoassay Medical Decision Levels

Controls which cover the MDL can reduce the number of Quality Controls required by laboratories. For example, Randox Acusera Lyophilised Immunoassay Controls contain particularly low levels of TSH, Ferritin and Vitamin B12 in the Level 1 control, eliminating the need for an additional control at extra expense:

Analyte Medical Decision Level Randox Level 1 IA Control Competitor Level 1 IA Control
TSH 0.1 or 0.27 uU/mL 0.15uU/mL 0.37 uU/mL
Vitamin B12 190 pmol/L 174 pmol/L 327 pmol/L
Ferritin 12 ng/mL 11.1 ng/mL 49.6 ng/mL

In this example the competitor offers an anaemia control with lower levels of TSH, Vitamin B12 and Ferritin at an additional cost. With Randox Acusera QC, only one control is required for anemia monitoring and detection.
