26 – 28 June 2017The Westminster Conference Centre, LondonRegistrations now open. Please click the link to register for this year’s event. https://nibscsogats.co.uk/home
This year’s workshop will run over 2.5 days (starting at 12pm on 26th) and will incorporate some exciting new topics such as the use of NGS in the clinical setting and a first look at bacterial molecular diagnostics. Following on from last year’s workshop we will also continue to address serological issues, day 3 will be dedicated to this. The serology day will include topics such as parasitology diagnostics and avidity testing. As we are addressing some new topics we would like to give delegates the opportunity to submit an abstract in these new areas. Here is a link to a preliminary outline of this year’s agenda - abstract topics are listed under the session ideas. If you have some data or experiences in these areas that you would like to share, then please submit a short abstract outlining your work (about 250 words) to SoGAT@nibsc.org by Friday, 10 March 2017. The SoGATS committee will review all abstracts and the outcome will be notified to delegates by mid-April.
You may also notice that our fondly known title of SoGAT has an extra letter (it’s not a typo)! After much discussion about the inclusion of the serological part of the workshop we have decided to include this in our title. We have also had some discussion in the committee regarding a title that gives new delegates a better understanding of our aims (SoGAT wouldn’t mean much to those that are new to the workshop!), therefore, we are expanding our title to Standardisation of Genomic Amplification Techniques and Serology/Standardisation of Infection Diagnostics (SoGATS/SID) - delegates will have a chance to have their say about this at this year’s workshop!

Corresponding low-positive in-run controls for monitoring the analytical sensitivity of these assays are also available (NIBSC codes 15/136 and15/138.
An interim WHO standard is available from NIBSC; it is coded 15/220 and is available to order through the NIBSC catalogue. Further studies are underway to develop a WHO Ebola Antibody International Standard.
The collaborative study is now complete and data is now being analyzed. A copy of the report from this study will be sent to all participants by April 2017.
This study will be presented to the WHO Expert Committee on Biological Standardisation in October 2017. If you wish to know anything about this study, please email Sheila directly at email@example.com
Adeno virus DNA
A pilot study is has been completed to understand whether a single HAdV type can harmonize across all types. A type 2 tissue culture grown isolate has been selected to be taken forward as the main candidate in a collaborative study to establish an international standard. If you wish to register an interest in participating in this study please email Sheila directly at firstname.lastname@example.org
This study will be presented to the WHO Expert Committee on Biological Standardisation in October 2017.

This reagent is intended for blood screening laboratories to use in the internal laboratory quality control of NAT assays for HBV, HCV and HIV-1. The reagent is intended to be included in each run as part of a continuing quality control program to monitor the assay performance. This reagent is not intended for any calibration purposes. It is coded 14/198 and is available to order through the NIBSC catalogue.
In 1994, the European Plasma Fractionation Association (EPFA), in conjunction with NIBSC, held a workshop to discuss the potential applications of NAT; from the detection of blood borne viruses in blood donation screening, to the production of “clean” plasma derived products. The meeting concluded that there was a need for standardization of NAT in the blood safety field, and that this warranted the formation of a group dedicated to standardization of NAT-based assays for blood borne viruses.
The 1st meeting of the International Working Group on the Standardisation of Genomic Amplification Techniques (SoGAT) for the virological safety testing of Plasma and Blood derived Products took place in April 1995. The group met to discuss standardisation techniques for blood viruses such as HCV, HBV, B19 as well as HIV. The rapid development of commercial assays for NAT and the appreciation of the scope of this new technology by many diagnostic and research laboratories, led to a decision that there was a need for reference materials for blood borne viruses.
Since 1994 the group have been paramount in the development of International Standards, reference panels and working reagents for HIV-1 RNA, HAV RNA, HCV RNA, HBV DNA and B19V DNA. Today, the group continues to support the development of new and replacement standards and reference panels and exchange information relevant to the scientific, technical and regulatory aspects of NAT.
Using the experience and knowledge gained by the SoGAT group focusing on blood virology, a new SoGAT group was established to address the area of clinical virology, which remains largely unstandardised. The International SoGAT Clinical Diagnostics Working Group is focused on the standardisation of NAT assays used in the diagnosis of clinical pathogens. The group was established in parallel to the SoGAT Blood Safety Working Group in 2008 and the first meeting took place at NIBSC in June of that year. The group has supported the development of International Standards for HCMV, EBV, BK and JC viruses for NAT, and new projects for adenovirus and HHV-6 NAT standardisation.
Since 2013, the SoGAT blood and clinical groups have met at an annual joint workshop. Participation is encouraged from blood and clinical laboratories, manufacturers of diagnostic assays and quality control reagents, providers of external quality assessment schemes, and regulatory and public health authorities.
The use of serological screening as a means of detecting viral infection has been in use since the early 1970’s and has been fundamental in diagnosis and monitoring of infection. The advent of NAT, described above, somewhat over shadowed the use of serology assays for a number of years, however serological screening still plays an important role in understanding the disease state. Serological tests are often less expensive compared to NAT and are therefore the test of choice for resource limited settings.
Many serological standards were developed to support the batch release of vaccines and are used conjunction with European Pharmacopeia monographs. However, greater understanding of the need to ensure comparability of diagnostic data has led to the increased use of the serological standards in the calibration of diagnostic assays. These standards however were those that were originally developed for vaccine release and are not necessarily suitable for diagnostic assay calibration.
In 2014 the SoGAT group raised the question - which forums are currently addressing standardisation of serology assays? To which the answer was very few, if any. Applying the experienced gained by running meetings to standardise NAT, it was decided that a new branch to the SoGAT meeting would be formed – SoGAT Serology.
