|Description||Various agonists are added to a stirred suspension of platelets and the decrease in light absorbed as platelets aggregate/agglutinate is measured.
Results are analysed by comparing the resultant aggregation curves with those of normal platelets.|
|Indication||Bleeding diatheses where the indication may be due to irregular platelet function.|
|Additional Info||Samples must be delivered to the laboratory by 11:00 am on the day of venepuncture.
This test is only available by specialist request from a Haematology Consultant and should be discussed with a member of the Haemostasis consultant team before arriving into the laboratory. All platelet testing is prearranged with the laboratory before samples are taken to ensure that relevant trained staff are available on the day to process the tests and ensure that we have contact information for the requestor.|
|Concurrent Tests||Platelet glycoproteins/nucleotides.
|Interpretation||Descriptive report of platelet aggregation in response to various agonists.|
|Collection Conditions||Citrate x 8 minimum (all citrate tubes must be filled to the line). Samples must be kept at room temperature and delivered to the laboratory immediately with minimal agitation.|
