Clinical Tests of Platelet Function - ScienceDirect

2019-1-1 · Platelet function testing began with the application of the in vivo bleeding time by Duke in 1910. 12 The technique consists of inflicting a small incision in the skin of the forearm or the earlobe, and recording the time required for a clot to form at the site of the incision and stop the flow of blood. The bleeding time was further refined by the Ivy technique and the availability of ...

2016-8-1 · Generally, platelet function testing for ASA is difficult to reproduce . For Clopidogrel, the reproducibility was expected to be higher. However, our results show that the reproducibility in a few-day horizon is poor and thus one should not rely on a single assay only. Therefore, to identify a patient as HPR, at least two assays should be used ...

2 天前 · In addition, the STS guidelines address the use of platelet function testing stating that because of the high negative predictive value, preoperative point-of-care testing to assess bleeding risk may be useful in identifying patients with high residual platelet reactivity after usual doses of antiplatelet drugs, and who can undergo operation without elevated bleeding risk.

Platelet Function Testing In Clinical Practice: Are We ...

2021-8-5 · In summary, accumulating data suggest platelet function testing as a valid tool to define the short and long-term prognosis in ACS/PCI patients. The development of point-of-care assays able to assess platelet function at the bedside will allow its more broad scale use and thus better define its prognostic value in various clinical scenarios.

ANTARCTIC: platelet function testing to adjust therapy ...

2017-3-25 · We carefully read the ANTARCTIC study by Guillaume Cayla and colleagues (Oct 22, p 2015),1 and would like to suggest a different interpretation of the results. The trial studied the utility of platelet function reactivity (assessed by VerifyNow) guidance in elderly patients (aged ≥75 years) with acute coronary syndrome and ST-elevation myocardial infarction (STEMI) who underwent

Testing Platelet Function - Hematology/Oncology Clinics

Platelet function tests have been traditionally used to aid in the diagnosis and management of patients with bleeding problems. Given the role of platelets in atherothrombosis, several dedicated platelet function instruments are now available that are simple to use and can be used as point-of-care assays. These can provide rapid assessment of platelet function within whole blood without the ...

COMPARISON OF TWO DIFFERENT METHODS TO

2008-10-1 · PURPOSE: Emerging data suggest that many patients are non responsive or only partially responsive to antiplatelet therapy. Different methods have been described to identify such patients. Traditionally light transmission aggregometry (LTA) is considered the gold standard. Helena Laboratories ICHOR/ Plateletworks® is a useful point of care test, based on platelet counts and provides a rapid ...

A person with normal platelet function test results may still experience excessive bleeding or inappropriate clotting during and after a surgery. Most samples for platelet function testing are only stable for a very short period of time.

Dual antiplatelet therapy guided by platelet function testing

2017-8-27 · Oral P2Y12 receptor inhibitors are key for secondary prevention of atherothrombotic events in patients with acute coronary syndromes, in particular those undergoing percutaneous coronary intervention (PCI)1.
