Description
Platelet function analysis assesses how well your platelets clot blood, often needed before surgery or to investigate unexplained bleeding or bruising, with costs typically ranging from ¥500–¥1,000 in China; ChinaMedicalHub helps coordinate hospital appointments and interpreter support.
Main Uses
Platelet function analysis is primarily used to: 1) Evaluate the risk of bleeding before surgical procedures, 2) Diagnose inherited and acquired platelet function disorders, 3) Monitor the effectiveness of antiplatelet therapy, 4) Investigate unexplained bleeding or bruising, 5) Assess the risk of thrombosis in certain clinical scenarios.
Normal Range
The normal range for platelet function analysis varies depending on the specific test and method used. Common indicators include: Platelet Aggregation (usually measured as a percentage of aggregation in response to various agonists, with normal values typically ranging from 70% to 100%), PFA-100 Closure Time (normal range is generally between 100-193 seconds for collagen/epinephrine cartridges and 80-180 seconds for collagen/ADP cartridges).
Low Values - Possible Causes
Low platelet function can be caused by: 1) Use of antiplatelet medications such as aspirin or clopidogrel, 2) Inherited disorders like Glanzmann thrombasthenia, 3) Uremia associated with chronic kidney disease, 4) Liver disease, 5) Bone marrow disorders.
High Values - Possible Causes
High platelet function or hyperreactivity is less commonly discussed but can be related to: 1) Thrombotic conditions, 2) Polycythemia vera, 3) Essential thrombocythemia, 4) Post-splenectomy state, 5) Certain inflammatory states or infections.
