Pineal Gland Tests
In most cases, no tests are indicated to assess the function of the pineal gland. While levels of melatonin could be measured in urine, blood, or saliva samples, these procedures are mostly done in research studies rather than for diagnostic purposes. Due to the size of the gland, imaging techniques might only provide limited information about the organ. When tumors develop, possible options include a brain biopsy, a magnetic resonance imaging scan, or a computerized tomography scan. For further diagnosis of circadian disorders, you may need to visit a board-certified sleep specialist to understand your sleeping patterns and associated problems. [7]
