Pseudotrombosytopenia · EDTA klottaa trombosyytit kasoiksi, tuloksena laskennallisesti trombosytopenia. · Tätä epäiltäessä tutkittava sitraattinäyte. · Ilmiö ...

... on ”Näyte tarkistettu mikroskoopilla, ei trombosyyttikasoja”, ei kyseessä ole pseudotrombosytopenia vaan todellinen trombosytopenia.

Erotusdiagnostiikassa on hyvä muistaa myös pseudotrombosytopenia, jossa EDTA aiheuttaa verihiutaleiden aggregoitumisen. Trombosyytit voidaan laskea ...

Pseudo-thrombocytopenia: platelet clumping or satellitism due to EDTA anticoagulant. Peripheral smear occasionally reveals clumping but not always. Send a repeat platelet count in citrate tube for any new diagnosis of thrombocytopenia.

Silloin kun niitä on liian vähän (trombosytopenia), ilmenee tavallista helpommin verenvuotoa nenästä, ikenistä ja muualtakin.

Pseudotrombosytopenia-epäilyissä on 11.10.2022 alkaen tilattavissa uusi tutkimus, jossa näyte otetaan natriumsitraatti-putkeen.

Author Information. Pathology - Journal of the RCPA: 2009 - Volume 41 - Issue - p 34. Free. Pseudothrombocytopenia is an uncommon and often unrecognised phenomenon that results in errors in the interpretation of platelet counts with consequent inappropriate clinical decisions or useless, and sometimes dangerous, therapeutic interventions.

Ethylenediaminetetra-acetic acid (EDTA) is widely used as anticoagulant in laboratory medicine. EDTA-dependent pseudothrombocytopenia is a rare phenomenon (i.e., around 0.1% in the general population), which is mostly due to the presence of EDTA-dependent antiplatelet antibodies that react optimally …

Pseudothrombocytopenia (PTCP) or spurious thrombocytopenia is an in-vitro sampling problem which may mislead the diagnosis towards the more critical condition of thrombocytopenia. The phenomenon occurs when the anticoagulant used while testing the blood sample causes clumping of platelets which mimics a low platelet count. [1]

Feb 4, 2021 · Pseudothrombocytopenia (PTCP), a relative common finding in clinical laboratories, can lead to diagnostic errors, overtreatment, and further (even invasive) unnecessary testing. Clinical consequences with potential life-threatening events (e.g., unnecessary platelet transfusion, inappropriate treatment including splenectomy or corticosteroids ...

Veren sivelyvalmisteessa nähdään trombosyyttikasoja. Pseudotrombosytopenia on harmiton ilmiö, mutta jos se jää toteamatta, potilas altistetaan tarpeettomille ja ...

Pseudothrombocytopenia is an in vitro decrease in platelet count related to the ethylenediaminetetraacetate (EDTA)-dependent exposure, and should be considered in the differential diagnosis. It is mostly due to the presence of EDTA-dependent antiplatelet antibodies that recognize the platelet receptors GP IIb-IIIa, which are modified when ...

Immunologinen trombosytopenia eli ITP (idiopaattinen trombosytopeninen purppura) on auto immuuni sairaus, jossa verihiutaleiden määrä veressä vähenee ja ...

Tästä trombosyyttien kasautumistaipumuksesta johtuvasta virheellisestä trombosytopeniasta käytettyjä termejä ovat mm. pseudotrombosytopenia, EDTA-trombopenia ja ...
