SIMPLE METHOD FOR PLATELET COUNTING

A method is proposed for counting the number of adhered platelets base d on the determination of lactate dehydrogenase activity in bulk after lysis of adhered platelets. This method was compared with the widely used radioisotope labelling technique. It was concluded that the prese nt lactate dehydrogenase method is effective in counting the adhered p latelets, as no significant difference was found between the readings of two methods when commercial polymers and glass were used as samples .
