Understanding Lab Tests for Adrenal Tumor or Cancer
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Adrenal tumors and cancers are complex conditions that affect the adrenal glands, which produce essential hormones. While imaging studies are typically the primary method for detecting tumors, blood tests play a crucial supporting role by measuring hormone levels that can be disrupted by these growths.
Top Recommended Test
Adrenocorticotropic Hormone (ACTH)
This test measures ACTH levels in the blood. Certain types of adrenal tumors or cancers can produce excessive amounts of ACTH, leading to abnormally elevated levels. Detecting high ACTH can be an important indicator of adrenal dysfunction and help healthcare providers assess the need for further evaluation.

The Role of Blood Tests in Adrenal Tumor Detection
Many adrenal tumors are functioning tumors, meaning they can overproduce certain hormones. Blood testing is fundamental for detecting these hormonal abnormalities, which can provide important clues about the presence of an adrenal tumor and help guide further diagnostic evaluation and treatment decisions.
Other Relevant Tests
Dehydroepiandrosterone (DHEA-s) Sulfate
This test measures DHEA-S levels, a hormone produced by the adrenal glands. Adrenal tumors or cancers can cause overproduction of various hormones, including DHEA-S. Elevated levels may indicate the presence of an adrenal tumor and can help healthcare providers monitor adrenal gland function.

Understanding Your Results
Abnormal hormone levels don't definitively diagnose adrenal cancer but can indicate the need for additional evaluation. Your healthcare provider will interpret these results alongside other clinical findings and may recommend imaging studies or additional tests to complete the diagnostic process.
