Platelet Assay

With access to blood donors, we offer unique non-clinical platelet assays that can help you understand platelet activation, aggregation, apoptosis, hemolysis, and hemagglutination.

Leverage the benefits of the unique test system ID.Flow®


We draw blood from donors directly at our test site allowing us to observe the effects of drugs on fresh, minimally manipulated whole blood, offering you invaluable insights into how drugs affect complex biological systems in the human blood including platelets.


ID.Flow is a highly advanced test system that ensures the continuous circulation of human whole blood and test substance at a regulated temperature of 37°C. Unlike plate-based in-vitro assays, ID.Flow uses fresh blood in motion, with only low levels of anticoagulants, making it highly relevant for platet studies.


FDA and EMA encourage the use of New Approach Methodologies (NAMs) to evaluate the immunotoxicity potential of new drugs. ID.Flow is a NAM accepted by regulatory authorities.

Platelet Assay

There’s reason to explore platelet activity when immune profiling any drug. Intentionally or unintentionally, a drug that triggers platelet activity unfolds a dramatic chain of events. Platelets are metabolically active cellular fragments, having no nuclei but a large number of surface receptors and granules. When their surface receptors are upregulated, platelets undergo a change in appearance, acquiring an irregular shape and a massive surface area that facilitates platelet aggregation. In addition, upregulation triggers the release of granule content, which includes ADP and other molecules that activate still more platelets – thus reinforcing the reaction. It’s no wonder that undesired thrombosis can appear so suddenly. Nonetheless, thrombosis may be just one platelet-related risk to clinical subjects.

Given the complexity of platelets’ role in the body, it’s vital to examine their activation with a physiologically relevant model. Immuneed’s test system, ID Flow is an excellent way of accounting for platelet, blood, and immune system intricacy. A dynamic model that mimics human blood circulation, it uses fresh blood from healthy subjects, rather than isolated cells removed from their complex environment. All blood components and cascade systems are intact, which means the many interactions and amplifications can be observed. Moreover, since blood enters the ID.Flow platform immediately, it doesn’t have to be pretreated with high levels of anticoagulants, as it would for in-vitro analysis
