&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;Phosphatidylserine/Prothrombin Antibody tests measure IgG and IgM antibodies in serum that target phosphatidylserine/prothrombin complexes. These antibodies are significant in diagnosing antiphospholipid syndrome (APS), an autoimmune disorder linked to clotting disorders and pregnancy complications. Testing helps confirm APS diagnosis, assess disease severity, and guide treatment decisions, typically involving anticoagulant therapy. Results are interpreted alongside clinical symptoms and other diagnostic tests to provide a comprehensive assessment of autoimmune-related thrombotic risks and management strategies.&lt;/span&gt;&lt;/p&gt;
&lt;hr /&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h3&gt;&lt;span style=&quot;color: #33cccc;&quot;&gt;&lt;strong&gt;WHAT IS IT USED FOR?&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style=&quot;color: #808080;&quot;&gt;This second-tier panel is recommended for detecting IgG and IgM antibodies targeting phosphatidylserine/prothrombin complexes in patients strongly suspected of having antiphospholipid syndrome (APS). These patients have tested negative for standard APS criteria laboratory tests such as lupus anticoagulant, IgG and IgM anticardiolipin/beta 2-glycoprotein I, and anti-beta 2-glycoprotein I antibodies.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #808080;&quot;&gt;The panel may also be beneficial in assessing patients previously diagnosed with lupus anticoagulant who are undergoing direct oral anticoagulant therapy. Additionally, it can serve as an indicator of thrombotic risk in individuals carrying antiphospholipid antibodies.&lt;/span&gt;&lt;/p&gt;
