Platelet function testing by Light Transmission Aggregometry (LTA) was introduced in 1962 by Born and O’Brien. This assay remains the gold standard.

Light Transmission Aggregometry
Employing Light Transmission Aggregometry (LTA), platelet aggregation is evaluated by measuring changes in light transmission after addition of platelet agonists to PRP (Platelet Rich Plasma).

Platelet aggregometry with LTA is indicated in different clinical situations :
- to diagnose platelet function defects predisposing patients to bleeding symptoms
- to control platelet concentrates prepared for transfusion
- to document the effects of antiplatelet drug treatment.
LTA can also be used for VWD investigation using RIPA test or confirmation of HIT.

Platelet function testing in clinical practice

The Thrombo-Aggregometer
A comprehensive offer that makes platelet function testing easier!
Using the gold standard technology – Light Transmission Aggregometry (LTA) – for the diagnosis of a wide variety of acquired and inherited platelet disorders, the TA 4-V3 or TA 8-V3 Thrombo-Aggregometer is a valuable choice for first-line Platelet Function Disorders exploration.
With less plasmas rejected thanks to the infrared wavelength used, time savings with up to 8 patients in parallel, an intuitive software and an easy-to-use panel of IVD and validated agonists, the TA 4-V3 or
TA 8-V3 is a valuable choice for productivity.
Real-time recording, reagent traceability and patient history make the TA 4-V3 or TA 8-V3 a valuable choice for reliability.
The TA 4-V3 or TA 8-V3 is the choice of simplicity with the remote connection, to visualise, analyse, comment, save and export patient results remotely.
