Platelet clumping is most commonly caused by pre-analytic errors such as improper or delayed sample mixing, clotted sample, over-filled or underfilled tubes, and time delay between sample collection and testing. It can also be an ex vivo phenomenon due to EDTA-dependent antibodies.

What causes platelets to clot?
Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.
How common is platelet clumping?
Results: Thrombocytopenic patients with viral infection had a higher frequency of platelet clumping than those with other diseases, which was statistically significant (13.8% vs. 6.5%, respectively: P = 0.003).
What causes blood platelets to clump?
Platelet clumping is most commonly caused by pre-analytic errors such as improper or delayed sample mixing, clotted sample, over-filled or underfilled tubes, and time delay between sample collection and testing. It can also be an ex vivo phenomenon due to EDTA-dependent antibodies.

What disease causes platelet clumping?
Platelets stop bleeding by clumping and forming plugs in blood vessel injuries. Thrombocytopenia might occur as a result of a bone marrow disorder such as leukemia or an immune system problem. Or it can be a side effect of taking certain medications. It affects both children and adults.
What does it mean if platelets are clumped?
Platelet clumping occurs when the blood platelets responsible for coagulation stick to one another to form clusters. The presence of platelet clumping has no clinical consequences other than preventing instruments from properly counting blood platelets.
How do you stop platelets from clumping?
Causes of platelet clumping include platelet activation (due to traumatic venipuncture) and EDTA-dependent antibodies that react with platelet glycoprotein IIb/IIIaglycoprotein IIb/IIIaIn medicine, glycoprotein IIb/IIIa (GPIIb/IIIa, also known as integrin αIIbβ3) is an integrin complex found on platelets. It is a receptor for fibrinogen and von Willebrand factor and aids platelet activation.https://en.wikipedia.org › wiki › Glycoprotein_IIb › IIIaGlycoprotein IIb/IIIa - Wikipedia. In the latter case, the clumping can be corrected by using blood collection tubes containing an alternative anticoagulant, such as sodium citrate.

Is platelet clumping normal?
Platelet clumping is a common laboratory phenomenon that complicates or precludes reporting of platelet count. It is often, but not always, a phenomenon commonly caused by the anticoagulant EDTA.
How common is Pseudothrombocytopenia?
Pseudothrombocytopenia may also result from in vitro platelet adherence (“satellitism”) to leukocytes. These phenomena are identified by examination of the peripheral blood film (Fig. 8.1). Pseudothrombocytopenia occurs in approximately 1 in 1000 people and is not clinically significant.

What medications can cause platelet clumping?
- Furosemide. - Gold, used to treat arthritis. - Nonsteroidal anti-inflammatory drugs (NSAIDs) - Penicillin. - Quinidine. - Quinine. - Ranitidine. - Sulfonamides.
Is it normal for platelets to clump?
A normal platelet count, even with clumping seen on a smear, is still usually estimated to be normal (or may occasionally be increased.
