Laboratories with a quality system accredited to the ISO/IEC 17025 standard have a definite advantage, compared to non-accredited laboratories, when preparing their facilities for the implementation of the principles of good laboratory practice (GLP) of the Organisation for Economic Co-operation and Development (OECD). Accredited laboratories have an established quality system covering the admi...

The International Society for Forensic Genetics (ISFG) has established a Paternity Testing Commission (PTC) with the purpose of formulating international recommendations concerning genetic investigations in paternity testing. The PTC recommends that paternity testing be performed in accordance with the ISO 17025 standards. The ISO 17025 standards are general standards for testing laboratories a...

The ageless question in metrology is, “What Test Uncertainty Ratio (TUR) is required to properly calibrate an instrument?” Numerous papers on guardbanding and statistical techniques have been published to address this question. Most recently, these discussions have focused on the very conservative “in-tolerance” conditions proposed by ISO Guide 25, draft 5. Although ISO Guide 25 is being replac...

Third-party accreditation is a valuable tool to demonstrate a laboratory's competence to conduct testing. Accreditation, internationally and in the United States, has been discussed previously. However, accreditation is only I part of establishing data credibility. A validated test method is the first component of a valid measurement system. Validation is defined as confirmation by examination ...

Metrological reliability in the sensory evaluation of products is fundamental importance ensuring comparability results. The issue uncertainties regarding measured data such contexts has led to new scientific approaches field analysis, which have become studies that seek compare results measurement and including wine. normative framework, ISO/IEC 17025:2017, replaces previous version 17025, pub...

Since 2013 to 2018, many successes have been achieved through the implementation of FDDM by DNA Databank Division (D13) Royal Malaysia Police (RMP) and Department Chemistry (KIMIA). Amongst those was increase in number samples analyzed 31,095 for year 2018; as compared 2017 which only 11,359; now total that successfully 96,037. With full commitment cooperation given both RMP KIMIA, profiles Sys...

We have implemented a simple, inexpensive, and fast procedure for validation and verification of the performance of pipettes mounted on automated liquid handlers (ALHs) as necessary for laboratories accredited under ISO 17025. A six- or seven-step serial dilution of OrangeG was prepared in quadruplicates in a flat-bottom 96-well microtiter plate, manually using calibrated pipettes. Each pipette...

ISO/IEC 17025:2017 and ISO 15189:2012 specify the requirements for competence of laboratories. The former refers to laboratories in general, whose activities include testing, calibration sampling followed by testing or while latter medical Despite differences between two standards reflecting specific needs each them is addressing, development these documents has, until now, similar paths. In th...
