Understanding Lab Tests for Cushing Syndrome
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Cushing Syndrome is a hormonal disorder caused by prolonged exposure to high levels of cortisol, often called the 'stress hormone.' This condition can lead to various metabolic changes throughout the body, including effects on blood sugar regulation.
Recommended Test
Glucose, Serum
This test measures blood sugar levels, which are often elevated in Cushing Syndrome. Excess cortisol increases glucose production by the liver and reduces insulin sensitivity, leading to high blood sugar levels. Monitoring glucose is essential for detecting diabetes or pre-diabetes, common complications of this hormonal disorder.

The Role of Blood Tests in Cushing Syndrome
While specialized cortisol tests are the primary diagnostic tools for Cushing Syndrome, additional blood tests are fundamental for assessing the metabolic complications associated with this condition. Elevated cortisol levels can significantly impact glucose metabolism, making blood sugar monitoring an important component of the diagnostic and management process.
Understanding the Connection
Cortisol naturally raises blood glucose levels as part of the body's stress response. In Cushing Syndrome, chronically elevated cortisol can lead to persistent hyperglycemia, insulin resistance, and eventually diabetes. Regular glucose monitoring helps healthcare providers assess the severity of metabolic dysfunction and guide appropriate treatment strategies.
