Sensitivities of radioimmunoassay and enzyme-linked immunosorbent assay for detection of hepatitis B surface antigen.

Radioimmunoassay (RIA) using Austria II (Abbott) was found to be more sensitive for the detection of HBsAg than the Hepanostika Micro-Elisa system (Organon Teknika), by a factor of 5- to 20-fold for subtype 'ad' (with one exception), and 2- to 5-fold for subtype 'ay'. The sensitivities of RIA and the enzyme-linked immunosorbent assay (Elisa) have also been evaluated in the screening of 178 selected serum samples contributed by 7 different laboratories. Of these, 149 were found to be positive for HBsAg by RIA, 142 were positive by Elisa and 36 were positive by CEP.

Transfusion therapy of thrombocytopenia: a reappraisal.

In the management of thrombocytopenia, platelet concentrated (PC) were given only to patients who had neither frank haemorrhage nor significant anaemia. Fresh whole blood (FWB) was preferred for those with the former, and platelet-rich red cell concentrate (PRC) for those with the latter complication. As a result of this approach it was found that only 6% of 412 therapy courses required PC, 37% required FWB and the remaining 57% required PRC. These are the findings of a year's survey of the requirements of patients in a predominantly urban population of approximately 1,200,000. The surprisingly high proportion of patients with complications requiring transfusion therapy, and the 24-hour availability of FWB and PRC in a metropolitan blood bank, have made PC transfusion an elective procedure and eliminated the need for a PC bank. Moreover, a better approach to treatment is available whilst a significant saving of blood donations is effected.
