Six exercises are distributed each financial year. Each survey includes both screening tests (level 1) and factor assays (level 2), and there are 4 distributions each of the thrombophilia screening exercise.


Details of tests to be included in each survey are indicated in survey newsletters three months prior to survey distribution.


All samples are of lyphilised plasma, from donors screened for hepatitis B surface antigen (HBsAg) and for antibodies to hepatitis C virus and human immunodeficiency virus types 1 and 2 (anti HIV-1+2). In the majority of cases, samples are from single donations.


In the majority of cases, samples are from single donations, from donors with previously identified haemostatic defects or from normal donors - where applicable, samples may be prepared from plasma pools.


In addition to six main scheme distributions, relevant supplementary exercises are distributed on an ad-hoc basis to address current issues in haemostasis. Click here for more information.
