&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;A serum cortisol test measures the levels of cortisol, a hormone crucial for stress response, metabolism, and immune function, in the blood. Cortisol exists in two forms: free and total. Free cortisol represents the biologically active form, while total cortisol includes both free and protein-bound cortisol. This test aids in diagnosing conditions such as Addison&#39;s disease, Cushing&#39;s syndrome, and adrenal insufficiency. It is also used to monitor treatment effectiveness in managing these conditions and to evaluate adrenal function. Results are interpreted based on the time of day, as cortisol levels vary throughout the day.&lt;/span&gt;&lt;/p&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;Evaluating cortisol levels is important in situations where abnormalities in cortisol-binding proteins or albumin are known or suspected. It&#39;s crucial in assessing adrenal function in critically ill or stressed patients to avoid unnecessary glucocorticoid therapy. Additionally, it serves as a second-line test when immunoassay cortisol results don&#39;t align with clinical symptoms or when patients are suspected of using synthetic steroids. Furthermore, it assists in distinguishing between primary and secondary adrenal insufficiency and aids in diagnosing Cushing syndrome.&lt;/span&gt;&lt;/p&gt;
