&lt;h2&gt;&lt;span style=&quot;color: #33cccc;&quot;&gt;&lt;strong&gt;Overview&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style=&quot;color: #808080;&quot;&gt;The ADAMTS13 Inhibitor Screen Assay is used on plasma samples as part of a full diagnostic profile to find the presence of ADAMTS-13 inhibitors. This helps in the diagnosis of congenital or acquired thrombotic thrombocytopenic purpura. This assay, performed through Fluorescence Resonance Energy Transfer (FRET), is available exclusively as part of a profile. Collection involves using light-blue top tubes containing sodium citrate, with 2 mL of plasma divided into 2 plastic vials, each containing 1 mL.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #808080;&quot;&gt;The collected specimen must be processed promptly, including centrifugation and aliquoting, with subsequent freezing to ensure sample integrity. Special attention is given to maintaining sample purity to avoid potential platelet contamination, and ensure accurate results. Additionally, priority specimens may be indicated for specific cases, requiring appropriate documentation and follow-up.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;

&lt;ol&gt;
&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #808080;&quot;&gt;Specimen must be collected before replacement therapy.&lt;/span&gt;&lt;/li&gt;

&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #808080;&quot;&gt;Aliquot plasma (1 mL per aliquot) into 2 separate plastic vials, leaving 0.25 mL in the bottom of the centrifuged vial.&lt;/span&gt;&lt;/li&gt;
&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #808080;&quot;&gt;Freeze plasma immediately (no longer than 4 hours after collection) at -20 degrees C or, ideally, below -40 degrees C.&lt;/span&gt;&lt;/li&gt;

&lt;ol&gt;
&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #808080;&quot;&gt;Double-centrifuged specimens are critical for accurate results as platelet contamination may cause spurious results.&lt;/span&gt;&lt;/li&gt;
&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #808080;&quot;&gt;If priority specimen, mark the request form, give a reason, and request a call-back.&lt;/span&gt;&lt;/li&gt;
&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #808080;&quot;&gt;Each coagulation assay requested should have its vial.&lt;/span&gt;&lt;/li&gt;
