My system already does automatic verification - do I need Valab?

All modern laboratory information systems (LIS) allow the setting up of autoverification rules. Setting up an "in-house" autoverification system is complex and requires a huge investment of time and resources. Each laboratory which engages in this approach finds itself reinventing the wheel to obtain a verification system which is still often incomplete and insufficient, based in the end on relatively few elements to decide on the coherence or not of the test results checked.

The Valab expert system is a dedicated tool, developed, tested and approved for over twenty-five years. The 25 000 combinatorial rules present right from the start in Valab are can be used immediately and the increasing number of Valab users testifies to the relevance and the reliability of its verification.

The Valab verification is dynamic - to judge the coherence of each result in the patient's report, Valab takes into account not only the biogical/clinical reference interval limits and demographic and contextual data of the patient, but also the influence of all the other results in the report (inter-parametric verification) and any previous results (dynamic delta check). Only an expert system is capable of taking into account so many combinations and judging in this way with full awareness the coherence of each test result.

The numerous sites which use Valab could have made do with the autoverification mechanisms already present in their system, they nevertheless preferred to trust Valab for this critical task.

Is Valab compatible with an ISO 15189 accreditation approach?

Using the Valab expert system brings the medical laboratory gains both in quality and in efficiency. Valab doesn't get tired, even in periods of intensive activity, and works 24 hours around the clock and 7 days a week. It is always constant in its way of working and contributes to a standardisation of practice and an increased coherence of the validation in the laboratory.

The reports verified by Valab are kept for a period defined by the laboratory and all the important events (operation, setup) are recorded in logs. The VALAB company provides Valab users with recommendations concerning the setting up of regular checking procedures to ensure the reliability of the system.

Many laboratories which use Valab are already accredited ISO 15189 or in the process of becoming so.

Would Valab change my way of working?

In a classic laboratory process, the persons approved to make the final validation of test results see displayed on their validation screens the results provided by the LIS.

When Valab is integrated into the process, the display provided by the LIS is typically enhanced with an additional column which contains the Valab verification flags (coherence indicators). Depending on the Valab integration into the LIS, the reports verified by Valab can be presented in two categories: "reports validated by Valab" and "reports not validated by Valab". In this way, the validator can concentrate directly on the problem reports and will see straight away, thanks to the verification flags, which results have raised a doubt during autoverification by Valab.

The task of validation is still the same, but by using Valab the reports which require special attention are identified immediately and the results directly concerned are clearly identified.

Can Valab work in my lab?

The Valab expertise model is applicable in any laboratory performing medical tests corresponding to the basic specialities (Biochemistry, Hematology, Coagulation, Blood Gases) or to the additional specialities and tests.

The specifics of each laboratory are defined at the level of the values of the biogical/clinical reference interval limits and the RCV values, of the units used, and of the referencing conventions used to describe the operating environment of the laboratory (codes of the tests used, identifiers of the requestors, etc.).

Before installing Valab, the customer provides this information to the VALAB company which can in this way prepare an initial setup perfectly adapted to the laboratory. This results in a Valab that is rapidly operational after installation.

How would Valab integrate with my LIS?

To be able to work in a laboratory, Valab must be connected to the LIS by a bidirectional network connection like any other instrument integrated into the system.

The LIS must be able to handle the sending of reports to Valab (which elements to send, at which moment, . . .) and the processing of the autoverification results returned by Valab (release of autoverification results, display of the autoverification flags on the validation screens, . . .) .

The Valab connection / integration is supported by an increasing number of LIS's.

The VALAB company provides technical assistance to the LIS supplier companies for all new requests for connection / integration of Valab into their systems.

Which information must I provide to obtain a Valab quotation?

With the aim of reflecting as closely as possible the autoverification needs of the site, the following criteria are taken into account to draw up a quotation:

  • the choice of one or more basic modules provided with Valab: Biochemistry, Hematology, Coagulation, Blood Gases
  • an estimate of the number of reports per day to be submitted for verification by Valab taking into account activity peaks and future requirements
  • any specifics linked to the context of the site or its operation (multi-lab site for example)
  • optionally, provision for coverage of additional tests not included in the basic modules - an extensive panel of ready-to-use VALAB-certified additional tests are available, and customers who wish to can also create their own expertise models for additional tests
  • number of users (number of floating licences)

What does the number of reports per day correspond to?

A "day" is a period of 24 hours from midnight to midnight, the reports-per-day counter is therefore reset every 24 hours.

A "report" corresponds to a new request number in the LIS and contains the results of one or more tests. If the LIS sends several partial reports during the day with the same request number, these sends will only count once for the 24h period in progress. If the LIS sends reports with different request numbers, even if they are for the same patient, each report will be counted as a new request.
