What is being analysed?
Platelet function analysis assesses the effectiveness of platelets in forming clots, which is crucial for proper blood clotting and wound healing.
What does the result mean?
The result indicates how well the platelets are functioning in the clotting process. It helps to diagnose various bleeding disorders or clotting abnormalities.
Why do the analysis?
Platelet function analysis is essential for diagnosing and monitoring conditions such as thrombocytopenia (low platelet count), platelet dysfunction, von Willebrand disease, and other bleeding disorders. It also guides the management of patients on antiplatelet therapy.
When to do the analysis?
Platelet function analysis is typically ordered when there are signs or symptoms of bleeding or clotting disorders, or when monitoring the effectiveness of antiplatelet therapy.
What sample is required?
A blood sample is required for platelet function analysis. This sample is usually drawn from a vein in the arm using a needle.
Is any type of prior preparation necessary?
Prior preparation is usually not necessary for platelet function analysis. However, it's essential to inform the doctor about any medications or supplements being taken, as certain medications can affect platelet function.
How is it used?
Platelet function analysis helps healthcare providers assess platelet activity and identify any abnormalities that may affect blood clotting. Based on the results, appropriate treatment or further diagnostic tests may be recommended.
What are the normal values?
Normal values for platelet function analysis can vary depending on the specific test being performed and the laboratory's reference range. However, in general, platelet function tests assess parameters such as platelet aggregation, adhesion, and secretion. Normal values ensure proper clot formation and haemostasis.
What does it mean to have altered values?
Altered values in platelet function analysis may indicate various conditions, such as thrombocytopenia, platelet dysfunction, von Willebrand disease, or other clotting disorders. Abnormal results may require further evaluation and management by a doctor.
Platelet Function Analysis Values:
Test Parameter Normal Range
|
Platelet Aggregation |
50-100% |
|
Platelet Adhesion |
>60% |
|
Platelet Secretion |
5-10 µmol/L |
These values may vary slightly depending on the specific test method and laboratory reference ranges. Abnormal values outside of these ranges may indicate platelet dysfunction or other underlying conditions requiring further evaluation and management.
