|ID:285 ||Platelet Function Test||Search Links: General Info : Protocols : Patient Info|
|Description||Investigation of platelet function, including platelet aggregation, nucleotide estimation and platelet surface glycoprotein analysis.|
|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.
Full Blood Count and blood film.|
|Dietary Requirements||NO aspirin or aspirin related products for 2 weeks prior to testing|
|Interpretation||Descriptive report of platelet aggregation and glycoproteins is provided. Platelet nucleotides and PFA-100 are reported against a reference range.|
