The 2018 Revision of the ISBER Best Practices: Summary of Changes and the Editorial Team's Development Process.

An increased need for specimens of reliable and consistent quality for research purposes requires the development of standardized policies and practices for the collection, handling, storage, retrieval, and distribution of specimens and specimen-related data. Providers of specimen resources should strive to incorporate new technologies and state-of-the-science approaches and thus ensure the availability of fit-for-purpose research specimens. Strategies to achieve quality outcomes and performance improvements often include adherence to established standards and implementation of best practices.

A Biospecimen Proficiency Testing Program for Biobank Accreditation: Four Years of Experience.

Biobanks produce and distribute biospecimens, ensuring their fitness for purpose and accurately qualifying them before distribution. In their efforts toward professionalization, biobanks can nowadays seek certification or accreditation. One of the requirements of these standards is regular participation in Proficiency Testing (PT) programs.

Assays for Qualification and Quality Stratification of Clinical Biospecimens Used in Research: A Technical Report from the ISBER Biospecimen Science Working Group.

This technical report presents quality control (QC) assays that can be performed in order to qualify clinical biospecimens that have been biobanked for use in research. Some QC assays are specific to a disease area. Some QC assays are specific to a particular downstream analytical platform.

Sustainability of Biobanks in the Future.

Human biorepositories are essential in providing high quality specimens that are well characterized. Biospecimens are used in basic, clinical, and translational research. However, as regulatory requirements and scientific demands increase the complexity of the daily operations of a biorepository, the cost of maintaining a biobank will increase.

Viable mononuclear cell stability study for implementation in a proficiency testing program: impact of shipment conditions.

The impact of shipping temperatures and preservation media used during transport of either peripheral blood mononuclear cells (PBMCs) or Jurkat cells was assessed, in view of implementing of a proficiency testing scheme on mononuclear cell viability. Samples were analyzed before and after shipment at different temperatures (ambient temperature, dry ice, and liquid nitrogen) and in different preservation media (serum with cryoprotectant, commercial cryopreservation solution, and room temperature transport medium). Sample quality was assessed by viability assays (Trypan Blue dye exclusion, flow cytometry, Cell Analysis System cell counting (CASY)), and by ELISpot functional assay.

Identification of evidence-based biospecimen quality-control tools: a report of the International Society for Biological and Environmental Repositories (ISBER) Biospecimen Science Working Group.

Control of biospecimen quality that is linked to processing is one of the goals of biospecimen science. Consensus is lacking, however, regarding optimal sample quality-control (QC) tools (ie, markers and assays). The aim of this review was to identify QC tools, both for fluid and solid-tissue samples, based on a comprehensive and critical literature review.

Biobanking past, present and future: responsibilities and benefits.

The review explores the field of biobanking as it has evolved from a simple collection of frozen specimens to the virtual biobank. Biorepository and biospecimen science has evolved in response to the changing landscape of external regulatory pressures, the advances made in the biological sciences, and the advent of the computer chip. Biospecimen banking is a growing enterprise crucial to health science research and other biological sciences.

The Cancer-Associated Virus Landscape in HIV Patients with Oral Hairy Leukoplakia, Kaposi's Sarcoma, and Non-Hodgkin Lymphoma.

Although HIV-positive patients are at higher risk for developing a variety of infection-related cancers, the prevalence of infections with the seven known cancer-associated viruses has not been studied. Luciferase immunoprecipitation systems were used to evaluate antiviral antibodies in four 23-person groups: healthy blood donors and HIV-infected patients with oral hairy leukoplakia (OLP), Kaposi's sarcoma (KS), or non-Hodgkin lymphoma (NHL). Antibody profiling revealed that all HIV-positive individuals were strongly seropositive for anti-gp41 and antireverse transcriptase antibodies.

Standard preanalytical coding for biospecimens: review and implementation of the Sample PREanalytical Code (SPREC).

The first version of the Standard PREanalytical Code (SPREC) was developed in 2009 by the International Society for Biological and Environmental Repositories (ISBER) Biospecimen Science Working Group to facilitate documentation and communication of the most important preanalytical quality parameters of different types of biospecimens used for research. This same Working Group has now updated the SPREC to version 2.0, presented here, so that it contains more options to allow for recent technological developments.

Associations between salivary gland histopathologic diagnoses and phenotypic features of Sjögren's syndrome among 1,726 registry participants.

Objective: To examine associations between labial salivary gland (LSG) histopathology and other phenotypic features of Sjögren's syndrome (SS).

Methods: The database of the Sjögren's International Collaborative Clinical Alliance (SICCA), a registry of patients with symptoms of possible SS as well as those with obvious disease, was used for the present study. LSG biopsy specimens from SICCA participants were subjected to protocol-directed histopathologic assessments.

Standard preanalytical coding for biospecimens: defining the sample PREanalytical code.

Background: Management and traceability of biospecimen preanalytical variations are necessary to provide effective and efficient interconnectivity and interoperability between Biobanks.

Methods: Therefore, the International Society for Biological and Environmental Repositories Biospecimen Science Working Group developed a "Standard PREanalytical Code" (SPREC) that identifies the main preanalytical factors of clinical fluid and solid biospecimens and their simple derivatives.

Results: The SPREC is easy to implement and can be integrated into Biobank quality management systems and databases.
