&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;OVERVIEW&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Diagnostic methods for identifying deficiencies in the alternative pathway related to conditions such as atypical hemolytic uremic syndrome (aHUS), dense deposit disease (C4HUS), and C3 glomerulonephritis (FBCA) include nephelometry (for C3HUS, C4HUS, FBCA, FHCA), an automated liposome lysis assay (COM3), and enzyme-linked immunosorbent assays (ELISA) for AH503, C4D, CBB, and SC5B9.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;This testing is conducted through the aHUS Complement Panel, S and P, which requires both plasma and serum specimens to be collected in designated containers. The specimens must be processed promptly and frozen within 30 minutes of collection. Patients should be fasting, and samples should not be collected within 48 hours after plasma exchange.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
