How does a platelet aggregation test work? Platelet Aggregation Testing – The platelets from a blood sample are put into tubes. Then different chemicals are added to the tubes to see if they make the platelets stick together (aggregate). A machine is used to detect this. The chemicals used are ones that make normal platelets stick together. These chemicals are called agonists .
