Physician Insight & Safety Protocols
“As a general practitioner, I understand that hormonal testing can be stressful. Please rest assured—our team is committed to guiding you through every step. Remember, never discontinue prescribed corticosteroids abruptly, as this can trigger life-threatening adrenal insufficiency. Always correlate suppression results with clinical context and imaging to avoid misdiagnosis of cyclic or pseudo-Cushing states.”
