Variability of anti-PF4/heparin antibody results obtained by the rapid testing system ID-H/PF4-PaGIA [PDF]
Recent studies have shown that a low clinical pretest probability may be adequate for excluding heparin-induced thrombocytopenia. However, for patients with intermediate or high pretest probability, laboratory testing is essential for confirming or refuting the diagnosis.

Relation Of Heparin Binding And Conformation In PF4 AND LA-PF4 (βTG)
Thrombosis and Haemostasis, 1981Platelet factor 4 (PF4) and low affinity platelet factor 4 (LA-PF4) are platelet-specific secreted proteins that bind to heparin. β-thromboglobulin (βTG) appears to be derived from LA-PF4 by proteolysis of four NH2-terminal residues. PF4 and LA-PF4 (βTG) show 50% sequence homology including four cysteine residues and two pairs of lysine residues near ...

It is shown by e.s.r. spectroscopy that a radical in γ-irradiated NH4PF6 and KPF6, previously identified as PF4, is in fact PF5–.

Abstract Abstract 227 RUNX1/CBFA2 (Core binding factor A2) is a major transcription factor involved in hematopoiesis. RUNX1 mutations are associated with mild thrombocytopenia, platelet dysfunction, and predisposition to acute leukemia.

SummaryShort chain polyphosphates (polyP) are pro-coagulant and pro-inflammatory platelet released inorganic polymers. The platelet chemokine platelet factor 4 (PF4) binds to lipid A on bacteria, inducing an antibody mediated host defense mechanism, which can be misdirected against PF4/heparin complexes leading to the adverse drug reaction heparin ...

The recent introduction of the determinations of platelet factor 4 (PF4) and beta-thromboglobulin (beta TG) by radioimmunoassay provided a new tool to obtain knowledge of in vivo platelet activation. We evaluated the plasma level of PF4 and beta TG in 14 normal subjects (mean PF4 7.7 ng/ml; beta TG 28.8 ng/ml), in 29 patients with chronic stable ...

Journal of thrombosis and haemostasis : JTH
Heparin-induced thrombocytopenia (HIT), vaccine-induced immune thrombocytopenia and thrombosis (VITT), and VITT-like disorders are caused by anti-platelet factor 4 (PF4)/polyanion and/or anti-PF4 IgG antibodies. The rapid anti-PF4/polyanion and anti-PF4 chemiluminescence assays differentiate between typical HIT (anti-PF4/heparin) and VITT antibodies ...
