<p>Create lab page for Platelet count with EM-focused content and references</p> <p><b>New page</b></p><div>==Background==<br /> *Count of circulating platelets; essential for primary hemostasis<br /> <br /> ==Normal Values==<br /> *Normal: 150,000-400,000/mcL<br /> *Thrombocytopenia: &lt;150,000/mcL<br /> *Thrombocytosis: &gt;400,000/mcL<br /> <br /> ==Interpretation==<br /> *Pseudothrombocytopenia: EDTA-induced platelet clumping is the most common lab artifact; confirm with peripheral smear or citrate tube<br /> *Mild thrombocytopenia (100,000-150,000): usually clinically insignificant<br /> *Moderate thrombocytopenia (50,000-100,000): liver disease, DIC, ITP, medications, hypersplenism<br /> *Severe thrombocytopenia (&lt;50,000): increased bleeding risk; consider TTP/HUS, HIT, ITP, DIC, bone marrow failure<br /> **Spontaneous bleeding risk increases significantly &lt;10,000-20,000<br /> *Platelet transfusion thresholds: &lt;10,000 (prophylactic), &lt;50,000 (active bleeding or invasive procedure), &lt;100,000 (neurosurgery)<br /> <br /> ==See Also==<br /> *[[CBC]]<br /> *[[Thrombocytopenia]]<br /> *[[ITP]]<br /> *[[TTP]]<br /> *[[DIC]]<br /> *[[Platelet transfusion]]<br /> <br /> ==References==<br /> &lt;references/&gt;<br /> <br /> [[Category:Labs]]</div>
