TEG PlateletMapping assay results may be misleading in the presence of cold stored platelets.

DISCUSSION: The PlateletMapping MAFIBRIN and MAADP test results may be misleadingly high with CSPs, particularly with the TEG 5000 analyzer, most likely due to constitutive activation of GPIIb/IIIa on CSPs during storage. TEG PlateletMapping results should be interpreted with caution following CSP transfusion. PMID: 32478898 [PubMed - as supplied by publisher]
